The Anonymous Widower

Cambridge South Station To Be Developed

To me, this was one of the highlights of the 2020 Budget today.

As I lived near Cambridge for over a dozen years and regularly played real tennis at the University, I know the scientific heartbeat of the City better than most.

I have discussed the problems of running a business in the City, with many, who are associated with some of the City’s most successful businesses. I have also funded several ventures in the area.

The same basic problems keep arising.

  • Lack of premises, offices and workshops, of all sizes and qualities.
  • Lack of staff to work in the ventures.
  • Lack of suitable housing, where staff moving to the City can live.
  • Staff are being forced to live further out and the roads, railways and other pubic transport systems don’t have the capacity.
  • Inadequate connections to Stansted Airport.

In the last few years, the transport has improved.

  • A sophisticated and award-winning Park-and-Ride running to five large car parks ringing the City has been developed.
  • The Park-and-Ride also caters for cyclists.
  • Cambridge North station has been opened close to the Cambridge Science Park and the A14 Cambridge Northern By-Pass, with a 450-space car-park and space for a thousand bikes.
  • The Cambridge Guided Busway has been developed across the City from Huntingdon station to Trumpington via Cambridge Science Park, Cambridge North station, Cambridge City Centre, Cambridge bus station, Cambridge station and Addenbrooke’s Hospital.
  • Addwnbrooke’s Hospital is a Major Trauma Centre.
  • The forecourts of Cambridge and Cambridge North stations have been developed to create good interchanges and meeting points.
  • Great Northern now has two fast and two stopping trains per hour (tph) between London Kings Cross and Cambridge and/or Cambridge North stations, with trains continuing alternatively half-hourly to Ely or Kings Lynn.
  • Thameslink has two tph between Brighton and Cambridge.
  • Thameslink also has two tph between Cambridge and London Kings Cross, which will be extended to Maidstone East station, within a couple of years.
  • Greater Anglia run an hourly service between Norwich and Stansted Airport via Ely, Cambridge North and Cambridge stations.
  • Greater Anglia run two tph between London Liverpool Street and Cambridge North stations.
  • Greater Anglia run an hourly service between Ipswich and Cambridge via Bury St. Edmunds and Newmarket stations.
  • All Greater Anglia trains are being replaced with new and much larger Class 755 or Class 720 trains.
  • CrossCountry run an hourly service between Birmingham New Street and Stansted Airport via Peterborough, March, Ely, Cambridge North and Cambridge stations.
  • The A14 and A428 roads are being improved between Cambridge and the A1.
  • The East West Railway between Reading and Cambridge via Oxford, Milton Keynes and Bedford is being developed and should open before the end of the decade.

But Cambridge still needs better links to the surrounding countryside and further.

  • Connections to Peterborough could be doubled to hourly.
  • Cnnections to Haverhill and Wisbech are poor.
  • East West Railway have ideas about improving connections to both East and West of Cambridge.
  • Better connections are needed at Addenbrooke’s to connect the rail system to the hospital and the Cambridge Biomedical Campus.

Cambridge South station would be the icing on the cake.

  • It could be the Southern terminus of a Wisbech service.
  • It could be on a service of at least four tph between Ely and Cambridge South stations via Waterbeach, Cambridge North and Cambridge stations.
  • It would bring Addenbrooke’s and the Cambridge Biomedical Campus within easy commuting of London.
  • It would be well-connected to Bedford, London, Milton Keynes, Oxford, Reading, Stansted Airport and Stevenage.
  • There have also been rumours, that the station could be connected to the Cambridge Autonomous Metro, which would be developed from the Cambridgeshire Guided Busway and the Park-and-Ride.

Cambridge South station would be the hub, that ties all the various routes together,

The station could be a fairly simple station to build, by just building platforms and buildings alongside the existing electrified line.

This Google Map shows the hospital. and the West Anglia Main Line running North-South to the West of the hospital.

Note the West Anglia Main Line running North-South to the West of the hospital.

Station Design

This page on the Network Rail web site gives a basic design.

  • Four platforms with step-free access via a footbridge and lifts;
  • Platforms with seating and shelter for waiting passengers;
  • A ticket office and ticket machines, along with automatic ticket gates;
  • Taxi and passenger drop off facilities:
  • Facilities such as a retail/catering unit, a waiting room and toilets;
  • Blue badge parking; and
  • Cycle parking.

The page then gives various location options.

Services

These are my take on the initial services, based on the current ones and those proposed by the East West Railway.

  • 1 tph – CrossCountry – Birmingham New Street and Stansted Airport, via Coleshill Parkway, Nuneaton, Leicester, Melton Mowbray, Oakham, Stamford, Peterborough, March, Ely, Cambridge North, Cambridge, Cambridge South and Audley End.
  • 1 tph – Greater Anglia – Norwich and Stansted Airport, via Wymondham, Attleborough, Thetford, Brandon, Lakenheath, Ely, Cambridge North, Cambridge, Cambridge South, Whittlesford Parkway and Audley End.
  • 1 tph – Greater Anglia – Ipswich and Cambridge South via Needham Market, Stowmarket, Bury St. Edmunds, A14 Parkway, Newmarket and Cambridge.
  • 2 tph – Greater Anglia – Cambridge North and London Liverpool Street via Cambridge, Cambridge South, Audley End, Bishops Stortford, Harlow, Broxbourne and Cheshunt.
  • 1 tph – Greater Anglia – Wisbech and Cambridge South via March, Ely, Cambridge North and Cambridge.
  • 2 tph – Thameslink – Cambridge and Brighton via Stevenage, London St. Pancras, East Croydon and Gatwick Airport.
  • 2 tph – Thameslink – Cambridge and Maidstone East via Stevenage, London St. Pancras and Blackfriars
  • 2 tph – Great Northern – Ely/Kings Lynn and London Kings Cross via Stevenage.
  • 1 tph – East West Railway – Norwich and Reading or Oxford, via Ely, Cambridge North, Cambridge, Cambridge South, Bedford and Milton Keynes.
  • 1 tph – East West Railway – Manningtree and Reading or Oxford, via Ipswich, Needham Market, Stowmarket, Bury St. Edmunds, A14 Parkway, Newmarket, Cambridge, Cambridge South, Bedford and Milton Keynes

Note.

  1. I have left out a few less important stations.
  2. I have extended the current Ipswich and Cambridge service to Cambridge South.
  3. I have added East West Rail’s proposed A14 Parkway station.
  4. I have added a Wisbech and Cambridge South service.

This simple service gives the following frequencies.

  • 6 tph – Ely and Cambridge North
  • 8 tph – Cambridge North and Cambridge
  • 10 tph – Cambridge and Cambridge South
  • 2 tph – Cambridge/Cambridge South and Stansted Airport
  • 1 tph – Cambridge North/Cambridge/Cambridge South and Kings Lynn
  • 8 tph – Cambridge/Cambridge South and London
  • 2 tph – Cambridge/Cambridge South and Ipswich.
  • 2 tph – Cambridge North/Cambridge/Cambridge South and Norwich.
  • 1 tph – Cambridge North/Cambridge/Cambridge South and Peterborough.
  • 6 tph – Cambridge/Cambridge South and Stevenage.

I feel strongly about the following.

  • If six tph is thought to be ideal between Cambridge/Cambridge South and Stevenage, then surely more services are needed between Cambridge and Ipswich, Kings Lynn, Norwich. Peterborough and Stansted Airport. Perhaps as many as four tph are needed to give a Turn-Up-And-Go service.
  • The frequency through Ely, Cambridge North, Cambridge and Cambridge should be as high as possible. With digital signalling ten tph must be possible.

At least Greater Anglia have plenty of Class 755 trains.

Conclusion

Rishi Sunak is right to build Cambridge South station.

You might even be able to argue, that the work done on the Cambridge Biomedical Campus could be key in fighting diseases like the coronavirus.

Economics Of Very Light Rail Between Cromer And Sheringham

In Very Light Rail Research On Track, I reviewed an article of the same name on Railway Gazzette International.

The article ,mentioned that the route between Cromer and Sheringham stations could be run by very light rail vehicles.

Very Light Rail Vehicles

Very Light Rail vehicles are defined as weighing less than a tonne per linear metre.

  • Warwick Manufacturing Group (WMG) found the most efficient propulsion system, was diesel-electric hybrid with battery storage. Was it nicked from an LEVC taxi?
  • An eighteen metre long vehicle will hold 56 seating and 60 standing passengers.
  • Will turn round times at the end of a shuttle route be reduced to perhaps two minutes as the driver only has to walk eighteen metres?
  • The article doesn’t give any speed estimates for very light rail vehicles. But I suspect 50-60 mph would be possible, as this is the operating speed of a Class 399 tram-train and very much the speed of typical single-decker buses.

If seated passengers weigh 90 kilograms with baggage, bikes and buggies and standing passengers perhaps 75 kilograms, this gives a vehicle weight of around 27.5 tonnes.

I estimate that a three-car Class 755 train, with the same passenger load would weigh around 108 tonnes or about 98 tonnes empty, which is about a tonne and a half per linear metre. A single-car Class 153 train is about 1.8 tonnes per linear metre.

Very light rail vehicles appear to be considerably lighter.

Cromer And Sheringham Line

This section of the Bittern Line can be considered a branch of the main section of the line, which links Norwich and Cromer stations.

  • It is single-track.
  • There is a simple cross-over outside Cromer station
  • It is just over 3.5 miles long.
  • Sheringham station is a single platform, that has recently been extended to take four-car Class 755 trains.
  • The only intermediate station is West Runton, which is a single platform.
  • Cromer station has two platforms.
  • Trains take eight minutes to go between Sheringham and Cromer stations.
  • The average speed of the train between Sheringham and Cromer is just 26 mph.
  • The maximum speed of the route is given in Wikipedia as 75 mph. As it is fairly straight it could probably be improved.

As four trains per hour (tph) between Cromer and Sheringham would take a total of 64 minutes, it would seem to be impossible to run such a schedule with current trains, given that the driver would have to change ends eight times in an hour.

Cromer Station

This Google Map shows the two-platform Cromer station.

Note the Northern platform, which is directly connected to the route to Sheringham.

A Split Service

Operation of a split service could be as follows.

  • A shuttle using the Northern platform 2 to Sheringham via West Runton.
  • A service to Norwich using the Southern platform 1.

I suspect to save signalling costs, that the Sheringham service could be run for most of the time under the principle of one-train on the line.

Could Four tph Run Between Cromer And Sheringham?

I suspect that a driver in running shoes could squeeze four tph out of a three-car Class 755 train.

Consider.

  • Three-car trains would save 160 metres of walking over four-car trains.
  • The Class 755 trains are designed for quick stops and have fast acceleration.
  • Versions of the trains are to be fitted with batteries.
  • Two crew working together with some automation might mean that the driver doesn’t have to change ends.
  • Three tph would be easier, as it would give more time for the driver to change ends.
  • Automation with the crew having an override could surely be used.

I don’t believe it would be impossible for a system of operation for this shuttle to be run using a Class 755 train.

Certainly, three tph is easier, but four tph is much more passenger friendly.

Could Two tph Run Between Cromer And Norwich?

Currently, trains take fifty-seven minutes between Norwich and Sheringham, which means that two tph would be very complicated, but not impossible.

Running the Cromer and Sheringham section independently, would mean that the time between Cromer and Norwich could be as low as forty-six minutes.

For a start, this means that a single train could work an hourly service between Cromer and Norwich.

It probable means that two trains could run a two tph service, provided that they could pass at a suitable place, where there are two tracks, as at North Walsham or to the South of Hoverton & Wroxham station.

Possible Service Patterns

I think the ideal service pattern would be something like this.

  • Two tph between Cromer and Norwich.
  • Three or four tph between Cromer and Sheringhan.

Currently, there is an hourly service along the whole route, which needs two trains to operate.

Two tph to and from Norwich and a shuttle would only need one extra train.

Savings With Very Light Rail

There are various ways cost savings can be made.

Cost Of The Vehicle

Leasing a single very light rail vehicle will be much less than leasing even an ancient one-car Class 153 train.

Obviously, for a reliable service, a spare will be needed, if a company had several routes that could be developed using very light rail, then the spare could be shared.

It looks like Greater Anglia are also thinking about other routes, so this may be an economic proposition.

One Train On Line Operation

Cromer and Sheringham could be run with a single train shuttling between the two stations and the points set, so that no other train could use the track.

This must surely reduce signalling costs.

Track Access Charges

Lighter trains have lower track access charges.

This could be a substantial saving, especially if there were four tph in both directions.

Cost Of New Infrastructure

Some routes that will be proposed for very light rail operation will need bridges and embankments to be built.

If the maximum weight of the vehicle is lower, this must surely reduce costs, as lighter structures could be used.

Fast Turnround Times

One of the limiting factors in providing frequent services over a short branch line is the time it takes to turn the train at each end of the route.

But in a very light rail vehicle, which is only eighteen metres long, the driver can probably change cabs in under two minutes, which is of the order of the time it takes to load and unload the train with passengers.

The only high frequency shuttle service over a short route in the UK is the one between Stourbridge Junction and Stourbridge Town stations.

  • The route is just 0.8 of a mile long.
  • It is served by Class 139 trains, which are just 8.7 metres long and can carry 20–25 seated, 30–35 standing passengers.
  • Trains run every ten minutes
  • The turnround time appears to be about two minutes

It is reputed to be the shortest operational branch line in Europe.

I can’t see why, that in a well-designed very light rail vehicle that is only twice the length of a Class 139 train, that the turnround time could not be the same time of two minutes.

It probably can’t be any shorter, in case several people turn up in wheel-chairs at the same time.

If we look at the Cromer and Sheringham route, I can see the following timing being possible for a well-designed shuttle train on the route.

  • Cromer to West Runton – two minutes
  • Stop at West Runton – one minute
  • West Runton to Sheringham – two minutes
  • Turnround at Sheringham – two minutes
  • Sherington to West Runton – two minutes
  • Stop at West Runton – one minute
  • West Runton to Cromer – – two minutes
  • Turnround at Cromer – two minutes

Note.

  1. The round trip would take fourteen minutes.
  2. I have assumed that the train is running at around 50-60 mph.
  3. The West Runton stop could be by request.
  4. There is only one train on the route at all times.

The round trip could be scheduled at four tph.

It must surely be an affordable way to provide a service.

I would also do the following.

  • As at Stourbridge have a second train on standby, to guarantee a reliable service, rescue a failed train and perhaps double the capacity at busy times.
  • Services between Cromer and Sheringham would be free.
  • Cromer, West Runton and Sheringham would be part of a group called Cromer stations, like Birmingham stations and Manchester station. So to book to any of the stations, you’d buy a ticket to Cromer stations.

If the latter ideas didn’t attract passengers then nothing would.

Greater Anglia would get their revenue on the onward services from Cromer.

Could The Cromer And Sheringham Shuttle Be Extended To Holt?

If the train crosses the level crossing at Sheringham station, the track extends all the way to Holt on the North Norfolk Railway.

This Google Map shows the two stations at Sheringham on either side of the level crossing.

The National Rail station is on the East side, with the heritage railway on the West.

Some heritage railways are certified to be able to run scheduled services to and from the main rail network.

This may even be possible here, to allow a service between Cromer and Holt.

Although the North Norfolk Railway seem to run a frequent timetable, I’m sure if there was the necessary coming together, that a service that was beneficial to all parties could be arranged.

Conclusion

Very light rail could be very exciting!

Mule Trains Between Liverpool And Norwich

I have done two trips to Liverpool in the last week.

On Saturday, I saw this collection of one-car Class 153 trains with a two-car Class 156 train thrown in.

They were forming one of East Midlands Railway‘s Liverpool and Norwich services.

And then yesterday, I had to travel between Liverpool and Sheffield and this was the collection of trains that took me.

So what was it like?

It started badly, with the driver announcing that because of the late arrival due to an undisclosed problem with the incoming train, that we would be leaving ten minutes after the planned departure time of 1551. He also indicated that our late departure meant that we would be stuck behind one of Northern’s services.

In the end, despite the gloomy faces of passengers we left twelve minutes late at 1603.

It was a bit like one of those classic films, where an ancient train escapes in the nick of time, with a lot of important and assorted passengers.

The asthmatic Cummins diesels under the train could be heard straining.

  • But the driver was at the top of his game and the train was running smoothly towards Manchester at close to 75 mph, which is the maximum speed of a Class 153 train.
  • At Manchester Piccadilly, the driver had pulled back two minutes.
  • There were obviously, no problems on the Dove Valley Line and the driver pulled back another minute before Sheffield, to arrive nine minutes late.

Looking at Real Time Trains, the train ran well until March (The place, not the month!), but there was some form of delay there and sadly it was thirty-four minutes late into Norwich.

The Train Was Clean

I should say there was nothing wrong with the train except for its design and age. It was also as clean as you can get one of these trains. The toilet, that I used was better than many I’ve used on trains and worked as it should.

Customer Service

East Midlands Railway had loaded a trolley and a steward and in the two hours I was on the train, he came through twice. The only problem for me, that he had no card machine, but I did find a fiver in my briefcase.

At least it was very drinkable. Even, if I hate those plastic tubs of milk, as they are difficult to open with one good hand.

Where Did Two Cars Go?

I had been fairly certain, that we had started with six cars, but we only arrived in Sheffield with four Class 153 trains.

I suspect that the trouble that delayed the train, concerned two cars and these were left on the naughty step or the end of Platform 6 in Liverpool Lime Street station.

Being Fair To East Midlands Railway

This service used to be run by a four-car formation of two-car Class 158 trains, but these have been causing trouble lately and they will be replaced by Class 170 trains cascaded from other operators.

But because of late arrivals of new trains the much better Class 170 trains haven’t arrived yet.

The driver, steward and other staff did a good job and I feel that the steward enjoyed it. No-one was abusive and stories were just exchanged, as we climbed across the Pennines in what by Sheffield was a very crowded train.

Class 153 trains may have been built as a stop-gap for short branch lines, but you couldn’t fault their performance.

Unless of course, one caused the delay at March, by expiring in a cloud of blue smoke.

Other Observations

These are other observations.

Scheduled Journey Times

On my journey the scheduled times were

  • Liverpool and Manchester Oxford Road – forty-seven minutes.
  • Liverpool and Sheffield – one hour and forty-eight minutes.
  • Liverpool and Nottingham – two hour and forty minutes.
  • Liverpool and Norwich – Five hours and twenty-seven minutes

The train considering the configuration, nearly achieved them.

It’s probably the motoring equivalent of doing the journey in a Morris Minor!

The Nine Stops Were Executed Perfectly

There were nine stops on my journey and eight took less than a minute, with Sheffield taking four, as the driver and crew changed.

A modern train like a Class 755 train, with fast acceleration and level boarding could probably save up to three minutes a time on each stop.

The Route Is A Genuine 75 mph Railway In Good Condition

I was checking the speed of the train on parts of the route and the driver had his motley crew at a steady 75 mph for long periods.

  • The train was riding well, indicating to me, that both trains and track were in reasonably good condition.
  • Note that 75 mph is the maximum speed of a Class 153 train.
  • The train recovered three minutes on the late departure from Liverpool.

I can see a faster train and improvements to the route, some of which are underway, could reduce the journey time by a few minutes.

Could Merseyrail’s New Class 777 Trains Work To The Bay Platform At Oxford Road?

Merseyrail’s new Class 777 trains will have the following performance.

  • A possible range of perhaps 40-50 miles on battery power.
  • An operating speed of 75 mph.
  • An acceleration rate of 1.1 m/sec², which is faster than a Class 153 or Class 170 train.
  • Fast stops due to regenerative braking, fast acceleration and level boarding.

As Liverpool Lime Street to Oxford Road is thirty four miles of which nine is electrified, I suspect that these new trains could extend Merseyrail’s Northern Line service from Hunts Cross to Manchester Oxford Road.

  • Two trains per hour (tph), but I’m sure four tph would transform the area.
  • I doubt any track modifications would be needed.

But would Liverpool and Manchester be able to sort out the local politics?

The Future Of The Liverpool And Norwich Service

This service will probably be spilt into two services.

  • Liverpool Lime Street and Derby, which could be run by TransPennine Express or Northern Trains.
  • Derby and Norwich, which would be run by East Midlands Railway.

As to the trains to be used, consider the following.

The Liverpool and Derby leg would probably need six trains, with the same number needed for Derby and Norwich, or twelve in total.

Currently, eleven or twelve is needed for the longer service.

Sections of the route like through Manchester and between Grantham and Peterborough are electrified.

There are even sections of route, where 125 mph running is possible.

Run reliably to an hourly frequency, I think that this service could attract passengers, especially, as it would serve Derby and extra stops like Ilkeston and Warrington West could be added.

This leads to the following trains being possibilities.

Class 802 trains – 125 mph bi-mode train of which TransPennine Express have 19 trains.

Class 185 trains – 100 mph diesel train of which TransPennine Express have 51 trains.

Class 804 trains – 125 mph bi-mode train of which East Midlands Railway have ordered 33 trains.

Class 755 trains – 100 mph diesel train of which Greater Anglia have 38 trains, which are based at Norwich.

Alstom Breeze hydrogen trains could be ideal for Liverpool and Derby.

Note.

  1. Greater Anglia and East Midlands Railway are both subsidiaries of Abellio.
  2. Developments of Class 755 trains could include battery and hydrogen versions.
  3. I suspect that 125 mph trains may be required for both legs, to maximise capacity on the East Coast Main Line and Midland Main Line.

Comparing Ride And Perceived Performance In Class 170 And Class 755 trains

I had intended to go to Norwich and Sheringham today, to take some pictures of Class 755 trains at Sheringham station.

Unfortunately, when I got to Norwich, the Sheringham train was a Class 170 train, so as I was running late, I came back.

But as I had travelled to Norwich in a twenty-year-old Class 170 train and returned in a brand-new Class 755 train, I was able to compare their ride and passenger performance on the well-maintained and straight Breckland Line.

The Class 170 train has a good ride and I’ve never felt to complain, even when travelling at 100 mph on some CrossCountry and Greater Anglia routes.

But I did feel that the Class 755 train had a smoother ride.

I did time the 755 at 90 mph on parts of the route, but at most times it was doing a motr sedate 75 mph.

Could it be that twenty years has enabled train dynamics to have been improved using computer simulation?

Intriguingly, the three-car Class 170 train is twenty percent heavier and has half the power of the four-car Class 755 train, which probably results in more sprightly acceleration for the new train.

Could this acceleration mean that the trains will be faster on a route with lots of stops?

Greater Anglia’s Norwich And Stansted Airport Service Starts On December 15th 2019

The annual December timetable change on December 15th 2019, will see Greater Anglia bringing in their new service between Norwich and Stansted Airport stations start as an hourly service.

The Route

Between Norwich and Ely stations, the route is on the Breckland Line.

  • It is not electrified, except for a short section at the Norwich end.
  • It is a full double-track, except for the single-track Trowse Bridge, that it shares with the Great Eastern Main Line on the approach to Norwich.
  • The operating speed is between 75-90 mph.
  • There are intermediate stations at Shippea Hill, Lakenheath, Brandon, Thetford, Attleborough, Spooner Row and Wymondham.

There is potential to increase the line speed, perhaps add some extra stations and remove the antiquated Trowse Bridge.

South from Ely through Cambridge to Stansted Airport, the route is a busy, fully-electrified double-track line.

The New Timetable

The Sunday journeys are as follows

  • Journey time appears to be a couple of minutes over two hours both ways.
  • Most services seem to leave Stansted at XX:09
  • First Northbound train is 08:18
  • Last Northbound train is 21:11
  • Most services seem to leave Norwich at XX:03
  • First Southbound train is 09:03
  • Last Southbound train is 20:03
  • Calling points appear to be Audley End, Wittlesford Parkway, Cambridge, Cambridge North, Ely, Brandon, Thetford, Attleborough and Wymondham.

Weekday services appear to be more-or-less similar.

  • Northbound services take around 6-9 minutes less than two hours.
  • Most services seem to leave Stansted at XX:48
  • First Northbound train is 05:27
  • Last Northbound train is 21:11
  • Southbound services take around 3-9 minutes less than two hours.
  • Most services seem to leave Norwich at XX:27 or XX:33
  • First Southbound train is 08:33
  • Last Southbound train is 19:27
  • Calling points are the same.

My Observations follow.

Convenience And Capacity

It is currently actually quicker by a few minutes to use the following services.

  • East Midland Railway’s service between Norwich and Ely
  • CrossCountry’s service between Ely and Stansted Airport.

These two trains can be very overcrowded at times and the new four-car Class 755 trains are much better and have more capacity, than the other services, which are often just two-car Class 158 or Class 170 trains.

Two Trains Per Hour Between Norwich And Stansted Airport

It also appears that the service with the single change at Ely will still be possible after the timetable change.

Thjis means that Norwich and Stansted Airport will have a two trains per hour (tph) service.

Train Timings

It would appear that the times between Cambridge and Norwich are very similar before and after the timetable change.

So it doesn’t appear that Greater Anglia are taking advantage of the superior performance of the new Class 755 trains.

How Many Trains Will Greater Anglia Need For The Norwich And Stansted Airport Service?

The current service between Norwich and Cambridge stations has a three hour round trip, so three trains are needed to provide the hourly service.

It looks like the Norwich and Stansted Airport service has a four hour round trip, so four trains will be needed to provide the hourly service.

Extending the Norwich and Cambridge service to Stansted Airport needs just one extra train.

How many extra passengers will Greater Anglia attract?

Whittlesford Parkway Gets An Extra Hourly Service To And From Cambridge

The extended hourly service between Norwich and Stansted Airport will call at Whittlesford Parkway station, which will increase the frequency on the busy commuter route between the Parkway station and Cambridge City Centre.

When we lived near Newmarket and C was practising as a barrister, she would sometimes go to Norwich up to tyree times a week. I wouldn’t be surprised to find that travellers between Whittlesford Parkway and Norwich stations are rather more numerous than the forecast.

  • The train will take about ninety minutes and driving about seventy-five.
  • The Class 755 trains have wi-fi.
  • There is a lot of parking at Whittlesford Parkway station.
  • Will Greater Anglia put a snack trolley on the train?

C would have certainly used the service, as Whittleford Parkway station was around fifteen minutes from where we lived.

What Will Greater Anglia Do With Lakenheath And Shippea Hill Stations?

These two stations are By Request and only get a few services a week.

Consider.

  • The modern Class 755 trains with their high performance and short dwell times could probably selectively stop at these stations without degrading the train timings.
  • Cambridge needs satellite development to provide housing and commercial development.
  • The future of RAF Mildenhall is uncertain and it could be sold for housing.
  • It could be argued that Cambridge needs a new Park-and-Ride station to the North to take the pressure off Ely station.

This Google Map shows RAF Lakenheath and the Breckland Line running Easy-West between Ely and Norwich.

Note.

  1. RAF Mildenhall is to the South-West of RAF Lakenheath.
  2. The railway going across the North side of the map through Shippea Hill, Lakenheath and Brandon stations.
  3. Most of the land is aricultural and very flat.

I wouldn’t be surprised to see substantial development of the railway through the area in the next ten or twenty years.

What Will Greater Anglia Do With Spooner Row Station?

Spooner Row station is another By Request station on the Breckland Line bertween Attleborough and Wymondham stations..

Spooner Row is not a busy station, although as this Google Map shows it is just off the main A11 road.

Noyr that Spooner Row station is in the South-East corner of the map.

Perhaps with more services and some increased car parking, it might pick up commuters and shoppers for Cambridge and Norwich it might become a convenient station for local residents travelling to and from Stansted Airport.

Could There Be A Norwich And Dereham Service?

Greater Anglia seems to be working closely with the Mid Norfolk Railway, which runs between Wymondham station on the Breckland Line to the town of Dereham.

  • In Aerial Pictures Show New Trains Housed In Mid-Norfolk, I showed how the heritage railway was storing trains for Greater Anglia.
  • According to Wikipedia, it would appear that several million pounds were spent to i8mprove the railway and its signalling, so that Greater Anglia’s new trains could be safely stored.
  • The line is mainly single track and signalled for an hourly service.
  • The yard at Dereham station seems to be regularly used for freight purposes, including loading damaged rolling stock on to road vehicles. It is also used by Network Rail for storage of track plant.
  • Train operating companies and heritage railways are increasingly working together for their mutual benefit.

As an InterCity 125 trains has recently been beyond Dereham, I wouldn’t rule out Greater Anglia running a new service between Norwich and Dereham, with a future aim of extension to Fakenham.

Because of the limitations of the track, it could probably only be a limited service.

Can Capacity Be Increased If Needed?

Having lived near Cambridge for nearly thirty years of my life, I believe that there will come a time, when one four-car train between Norwich and Stansted Airport will not be enough.

  • Two tph could be run on the route, which is relatively lightly used by other services.
  • Longer trains could be created or two three-car trains could be run as a six-car train.
  • The current speed limit of 75-90 mph of the Breckland Line,  can probably be increased closer to the 100 mph of the Great Eastern Main Line.

Higher speeds would shorten journey times and increase capacity.

Could We See 125 mph Trains From Kings Cross To Kings Lynn And Norwich?

In Call For ETCS On King’s Lynn Route, I talked about putting digital signalling on the Kings Cross and Kings Lynn route and running 125 mph trains via Cambridge.

If the Kings Cross and Kings Lynn route were to be upgraded for faster running, this would also upgrade the proposed Kings Cross and Norwich route as far as Ely.

This would make it very feasible to run the following serrvices using 125 mph trains like Class 800 trains.

  • Kings Cross and Kings Lynn
  • Kings Cross and Norwich

Because of their speed these trains would help to open up capacity between Hitchin and Kings Cross.

I feel that these 125 mph bi-mode trains could do the trip between Kings Cross and Norwich in ninety minutes, which would match the time via Ipswich.

Do I Have Any Criticism?

My main criticism is that the service between Norwich and Stansted Airport, doesn’t have trains that run early and late enough.

Wil lthe service be timed to better fit the services out of the Airport?

Further Development Of The Breckland Line

This report in the Ely Standard from 2015, is entitled Could Railway Revolution See New Station Built at Ely North?.

These improvements are listed.

  • A new four-platform station North of Ely would improve connectivity.
  • A service between Kings Cross and Norwich via Cambridge is suggested.
  • Improvements in services across East Anglia.

A cost of a billion pounds is mentioned.

125 mph Trains From Kings Cross To Kings Lynn And Norwich

In Call For ETCS On King’s Lynn Route, I talked about putting digital signalling on the Kings Cross and Kings Lynn route and running 125 mph trains via Cambridge.

If the Kings Cross and Kings Lynn route were to be upgraded for faster running, this would also upgrade the proposed Kings Cross and Norwich route as far as Ely.

This would make it very feasible to run the following serrvices using 125 mph trains like five-car Class 800 trains.

  • Kings Cross and Kings Lynn
  • Kings Cross and Norwich

The two services could even split and join at the proposed Ely North station to make full use of the paths into Kings Cross.

The 125 mph or more operating speed of these trains on the East Coast Main line would help to increase capacity between Hitchin and Kings Cross.

I estimate that these 125 mph bi-mode trains could do the trip between Kings Cross and Norwich in ninety minutes, which would match the time via Ipswich.

Norwich could have the following services.

  • Three tph to and from London via Ipswich
  • Two tph to and from London via Cambridge
  • Two tph to and from Stansted Airport via Cambridge.

It sounds fantastic, but if we are to get travellers out of their cars, they must be given a high quality train service.

Conclusion

The improved Norwich and Stansted Airport service will be the first major improvement brought in by Greater Anglia.

The East-West Rail Link Plans For Services Between Reading And East Anglia

This report on the East-West Rail web site is entitled Eastern Section Prospectus and gives full details of their proposals for the train services along the East-West Rail Link.

This post is particularly about services to Reading and the report says this about services between Reading and East Anglia.

Proposed Core Train Services

This is a sentence.

It has been assumed that, by this stage, a half hourly service will operate on the Central and Western sections between Oxford – Cambridge.

The report then goes on to add.

25 minutes are added to the Oxford journey time to represent the option of one service being extended to / from Reading with a Reading – Oxford non-stop.

So that looks like there will be a core hourly service between Reading and Cambridge, which will take 98 minutes.

The report then goes on to detail how various towns and cities in East Anglia will be connected to Reading.

Bury St. Edmunds

2h16 hourly with cross-platform changes at Cambridge and new A14 Parkway station.

Great Yarmouth

3h14 hourly direct

Ipswich

2h43 hourly with cross-platform changes at Cambridge and new A14 Parkway station.

Lowestoft

3h30 hourly with change at Norwich and cross platform change at Reedham.

Norwich

2h40 hourly direct

Trains For The Route

It looks like there will be two direct hourly train services.

  • Reading and Great Yarmouth via Cambridge and Norwich, which will take three hours and fourteen minutes.
  • Oxford and Ipswich via Cambridge and Bury St. Edmunds, which will take two hours and nineteen minutes.

The long term service pattern, envisages extending the Oxford and Ipswich service to Manningtree, which would add twenty-five minutes.

These are long services and given the overcrowding that happens on the current service between Norwich and Liverpool, I would think that the trains should be as follows.

  • At least four or five cars.
  • An on-board buffet.
  • At least 100 mph operation.

I also think the trains should be bi-mode trains, able to use 25 KVAC overhead electrification or onboard power.

How Many Trains?

It looks like the Reading and Great Yarmouth service would be a seven-hour round trip, which would need seven trains.

The future Oxford and Manningtree service would be a six-hour round trip, which would need six trains.

So add in an allowance for maintenance and a spare, I suspect the fleet should be sixteen trains.

Future Stansted Airport Train Services

Currently, the following services go to Stansted Airport station, in trains per hour (tph)

  • Four tph – Stansted Express – Liverpool Street
  • One tph -CrossCountry – Birmingham New Street via Cambridge, Peterborough and Leicester
  • One tph – Greater Anglia – Cambridge via Audley End and Whittlesford Parkway

Greater Anglia have plans to change the services.

  • Extend the Norwich and Cambridge service to Stansted Airport.
  • Reintroduction of a Stansted Express service between the Airport and Stratford is mentioned in Wikipedia.

With two very long and one shorter platform, the Airport station has plenty of capacity.

Stansted Express Journey Times And Trains Required

Currently, Stansted Express services run at a frequency of four tph, that take fifty minutes between London and the Airport.

If a turnround time of ten minutes is added, then it takes trains two hours to do a round trip between London and the Airport.

So this means that thse numbers of trains are needed for the following frequencies.

  • One tph – Two trains
  • Two tph – Four trains
  • Four tph – Eight trains

As Greater Anglia have ordered ten Class 745/1 trains for Stansted Express, these would be able to provide a reliable service with eight in service, one as a spare and one in maintenance.

A Stansted Express service to Stratford would take the same time and would need similar numbers of trains.

Norwich and Stansted Airport Journey Times And Trains Required

The timing for the proposed service between Norwich and Stansted Airport, can be estimated by taking the timing of current services.

  • Norwich and Cambridge – One hour 20 minutes
  • Cambridge and Stansted Airport – 30 minutes

Both services are run by reasonably-modern 100 mph diesel trains.

Add in a ten minute turnround at both ends of the route and it should be possible to schedule a Stansted Airport and Norwich round trip in four hours.

Greater Anglia is introducing new bi-mode Class 755 trains on this route.

  • The trains will be designed for fast stops.
  • The trains will run on electricity on the nearly forty miles between Stansted Airport and Ely and around Norwich.
  • The trains will run on diesel between Ely and Trouse Junction, just to the South of Norwich.
  • The trains will probably be abe to achieve 100 mph on a good proportion of the route.
  • The trains will probably be four-cars.

It would need four trains to run the proposed one tph service.

The current Norwich and Cambridge service probably needs three trains, so extending to Stansted Airport will need an extra train.

This seems to be good value for passengers, the Cities of Cambridge and Norwich, Stansted Airport and Greater Anglia.

Could There Be A Norwich And London Service Via The West Anglia Main Line?

I can remember seeing steam-hauled expresses thundering between Liverpool Street and Norwich in the 1950s, through places like Brimsdown.

They are long gone, but they gave places like Wymondham and Thetford a direct rail link to London.

Greater Anglia’s future plans will connect these towns and others directly to Stansted Airport, but could they go all the way to London?

What do the mathematics show?

The section timings of a Norwich and London service via Cambridge and Stansted Airport would be as follows.

  • Norwich and Cambridge – One hour 20 minutes
  • Cambridge and Stansted Airport – 30 minutes
  • Stansted Airport and London – 50 minutes

This is just two hours and forty minutes.

Add in a few minutes for the reverse at Stansted Airport and the turnround at either end and I believe a round trip could be comfortably within six hours.

It would therefore mean that six trains would be needed to run an hourly service between London and Norwich.

  • Stops could be Tottenham Hale, Broxbourne, Harlow Town, Bishops Stortford, Stansted Airport, Audley End, Whittlesford Parkway, Cambridge, Cambridge North, Ely and all stations to Norwich.
  • The London terminal could be Liverpool Street or Stratford.
  • If Stratford were to be used, trains could be turned round in the High Meads Loop.
  • Trains would be Class 755 trains, which are bi-mode and capable of 100 mph running.
  • Between London and Ely, the trains would take advantage of the electrification.

The service would give a lot of stations a direct connection to Stansted Airport, that would be complimentary to the Stansted Express.

It would require just two more trains, than the planned Norwich and Stansted Airport service.

The advantages of the service would be.

  • Stations between Thetford and Norwich would get direct London and Stansted Airport services.
  • Stratford would get a very useful direct service to Stansted Airport.

Greater Anglia would serve two markets with the extended service and just two extra trains, over the planned service.

If Greater Anglia say a London and Norwich via Stansted Airport service will never happen, they are being economical with the truth.

Could Class 755 Trains With Batteries Bridge The Electrification Gap,Between Ely And Trowse Junction?

The distance between the electrification at Ely station and Trowse Junction, South of Norwich, is just under fifty-three miles.

I believe that the tri-mode four-car Flirts for Trains for Wales are similar to Greater Anglia’s Class 755 trains, with three of the Deutz diesel engines replaced with 100-120 kWh batteries.

Would this be enough power to take the train across the electrification gap?

Consider.

  • There is electrification at both ends and the batteries could be full, on entering the unelectrified section.
  • The route is very gentle.
  • There are a few stops, but the trains will have regenerative braking to charge the batteries.
  • The trains could retain a single diesel-engine,, should livestock on the line cause the service to be suspended.

For these and other reasons, I suspect that in a couple of years, diesel will be relegated to emergency use only between Norwich and Stansted Airport.

The Herd Of Wannabe Unicorns In The Room

Other places have elephants, but the City of Cambridge has herds of wannabe unicorns.

For those of you, unfamiliar with the term, Wikipedia defines unicorn like this.

A unicorn is a privately held startup company valued at over $1 billion.

Cambridge is expanding at a fast rate and it needs public transport systems to bring in the workers, visitors and investors.

  • A new Cambridge North station has been built.
  • A guided busway linking Addenbrooke’s and Papworth Hospitals and the Cambridge Biomedical Campus to the City Centre has been built.
  • A new Cambridge South station is being planned.
  • The East-West Rail Link will connect Cambridge to Oxford.

Road travel in the local area is not an option.

Currently, most rail services radiate from Cambridge station, but like London and other cities are proving, Cambridge needs Cross-City services.

A high-frequency North-South route is being created  across the City.

  • To the North of the City is Ely station.
  • North of Ely station, lines fan out to Peterborough, Kings Lynn and Norwich.
  • From North to South across the City, there will be Waterbeach, Cambridge North, Cambridge and Cambridge South  stations.
  • South of Cambridge South station, lines will fan out to Bedford and Oxford, Royston, Hitchin and Kings Cross and Audley End, Stansted Airport and Livepool Street.

In addition routes to Bury St. Edmunds, Ipswich and Felixstowe reach out to the East.

The current North-South train services include.

  • 1 tph – Birmingham New Street and Stansted Airport
  • 1 tph – Kings Lynn and Kings Cross
  • 1 tph – Cambridge and Norwich
  • 2 tph – Cambridge and Brighton
  • 2 tph – Cambridge and Liverpool Street
  • 2 tph – Cambridge and Kings Cross

The number of these services will grow.

Will More Stations Be Built Or Reopened Between Stansted Airport And Norwich?

I know the route, South of Cambridge better than I know it to the North.

To the South of Cambridge, the current stations could be sufficient, with improved car and bicycle parking and provision for electric cars.

To the North, there appear to be new housing developments under consideration and surely, these will need good public transport to and from Cambridge.

Does The Norwich and Stansted Airport Service Need Two Trains Per Hour?

I have a feeling that Greater Anglia think, that East Anglia’s generally one tph services between major towns and cities is not enough.

Greater Anglia have said they will do the following.

  • Increase the Ipswich and Norwich frequency from two to three tph.
  • Run two tph between Ipswich and Kennett via Bury St. Edmunds.

I talked previously about Cambridge and its  herd of wannabe unicorns.

I believe strongly, that the Cambridge Effect will in a couple of years, mean that the frequency between Norwich and Stansted Airport will need to be doubled.

But will Greater Anglia have enough trains?

Greater Anglia are  purchasing a fleet of 38 Class 755 trains with a total of 138 carriages to replace 27 assorted trains with a total of 58 carriages.

  • This is a forty percent increase in the number of trains.
  • This is nearly two and a half times as many carriages.
  • The average number of carriages per train is raised from 2.1 to 3.6.

That is a massive increase in train capacity.

There should be enough for either.

  • Eight trains for two tph between Norwich and Stansted Airport.
  • Twelve trains for two tph between Norwich and London via Stansted Airport.

These would be increases of four and eight trains respectively on Greater Anglia’s  current plan for a one tph service between Norwich and Stansted Airport.

Conclusion

Greater Anglia have enough trains to run a two tph service between Norwich and London via Stansted Airport.

I believe that the Cambridge Effect will create enough demand to necessitate expansion of the proposed one tph service between Norwich and Stansted Airport into a Norwich and London via Stansted Airport service.

  • Frequency will be two tph.
  • New commuter-friendly stations could be built.
  • The Southern terminal could be Stratford to give a second route to Stansted Airport from London.

Greater Anglia would be satisfying two markets with one train.

InterCity Quality For Rural Routes

The title of this post is a quote from the Managing Director of Greater Anglia; Jamie Burles about the Class 755 trains in this article on Rail Magazine.

This is the complete paragraph.

Burles said of the Class 755s: “These will be the most reliable regional train in the UK by a country mile – they had better be. They will be InterCity quality for rural routes, and will exceed expectations.”

Initially, the Class 755 trains will be deployed between Norwich and Great Yarmouth stations.

  • It is 18.4 miles long
  • There are four intermediate stations.
  • Trains currently take thirty-three minutes.

It is certainly not your traditional InterCity route and it only runs at a maximum frequency of two trains per hour (tph).

Consider.

  • Norwich is a City of over 140,000.
  • Great Yarmouth is a town of 40,000.
  • There are lots of business and leisure reasons to travel between the two.
  • The A47 road between the two is totally inadequate.

Greater Anglia are purchasing a fleet of 38 trains with a total of 138 carriages to replace 27 trains with a total of 58 carriages.

  • This is a forty percent increase in the number of trains.
  • This is nearly two and a half times as many carriages.
  • The average number of carriages per train is raised from 2.1 to 3.6.

That is a massive increase in train capacity.

I don’t believe that Greater Anglia will park these trains in a siding, but use them to increase frequencies.

  • Will the 100 mph operating speed of the trains allow a round trip between Norwich and Great Yarmouth to be done in after an hour?
  • Will the frequency be increased to up to four tph?

If this can be arranged then Greater Anglia could need as few as four trains to run a Turn-Up-and-Go service between Norwich and Great Yarmouth.

How many passengers would that attract to the route?

Comparing Three-Car Class 755 And Class 170 Trains.

Some three-car Class 170 trains were bought some years ago, to run services between London and Great Yarmouth.

In recent years, they have become the mainstay of Greater Anglia’s regional routes.

  • Ipswich and Cambridge
  • Ipswich and Peterborough
  • Norwich and Cambridge

All three routes are currently run at a frequency of one tph.

These trains have the following specification.

  • 100 mph operation
  • Two-class layout.
  • Between 100 and 200 seats.

They have proven to be a  capable train for the routes and appear to have been driving increasing traffic levels.

It should also be noted that other operators use these trains on routes including.

  • Birmingham and Stansted Airport
  • Cleethorpes and Manchester Airport
  • Cardiff and Nottingham

I think it is true to say that Class 170 trains are 100 mph trains for running on InterCity routes that can’t justify a full-size train like a bi-mode Class 802 train.

Some operators will also be running five-car Class 802 trains on routes that have been run in the past or still are run by Class 170 trains.

The Class 755 trains are 100 mph trains, which Greater Anglia are using in two sizes.

  • Class 755/3 train – three cars with 167 seats
  • Class 755/4 train – four cars with 229 seats

The longer trains will probably be used on Greater Anglia’s longer regional routes.

  • Ipswich and Cambridge
  • Colchester and Peterborough
  • Norwich and Stansted Airport via Cambridge
  • Liverpool Street ans Lowestoft via Ipswich

Note that the last three routes are electrified for nearly have the route.

Except for the Ipswich and Cambridge route, these routes are longer than those run in the past and these routes will probably need four-car trains with InterCity interiors and service.

The Liverpool Street and Lowestoft service of the 1960s and 1970s had a buffet car and passengers on this route will at least expect a trolley service of drinks and snacks.

I very much feel that the Class 755 trains will in a worse case be better than the Class 170 trains, that have run InterCity services in the past.

Will Class 755/3 And Class 755/4 Trains Have The Same Interiors?

Greater Anglia haven’t said definitely that the interiors in the two classes of train will be the same, but I think it will be likely, with respect to the ease of building and maintaining the trains.

This video shows the train being tested at Diss.

Unfortunately, it doesn’t show the interior.

So I’ll have to wait until the end of June to have a look at a real train.

It should also be noted that Class 755 trains can be lengthened by adding extra trailer cars.

So it would be unlikely that the interiors in the driver and trailer cars were different, as this would mean that shuffling of cars could create a train with a mixed interior.

Conclusion

Consider.

  • Some of the Class 755/4 trains will be running InterCity services.
  • Both Class 755 variants are capable of 100 mph running.
  • Ease of building and maintenance probably requires identical interiors.

It would appear that all services where Class 755 trains are used, will get the same InterCity passenger experience.

Although some services could be slower than InterCity services, due to track limitations.

Will Abellio use a similar philosophy, with the new fleet for East Midlands Railway?

Norwich-In-Ninety Is A Lot More Than Passengers Think!

But, I very much expect that Greater Anglia know what they are doing.

I came up to Norwich on the 1100 train, which was timed to get in at 1230. According to the driver, there were signalling problems at Manningtree, which meant we arrived in Norwich twenty-one minutes late.

I was going on to Cromer or Lowestoft. So by the time I’d had a cider and bought a ticket, I didn’t leave Norwich until 1345 for Cromer. But I did have time by the sea to take a few pictures and have a coffee and a gluten-free scone, before getting the return train to Norwich.

Back at Norwich, I had a choice of two trains.

  • The 1700 stopping at just Ipswich and Norwich
  • The 1703 stopping at Diss, Stowmarket, Ipswich and a few other places.

I was booked on the 1700, from where I’m writing this note on my phone.

These are some of my observations.

Operating Speed

I have just travelled between Norwich and Ipswich in thirty minutes, with Speedview on my phone reading within a couple of mph of 100 mph all the way from where we got to operating speed South of Norwich to where we slowed for Ipswich station.

Diss, Stowmarket and Nedham Market stations were passed at almost 100 mph

Ipswich to Colchester was at a slower 90 mph, but then from Marks Tey to just before Chelmsford, the train was back to around 100 mph.

Speeds between 70 and 90 mph were held from Chelmsford to Liverpool Street, which was reached at 1830 as scheduled.

Acceleration

I got the impression, that the acceleration of the train wasn’t up to the operating speed. Certainly, it didn’t seem to accelerate as fast as an InterCity 125,

But then we’re talking about a rather puny Class 90 locomotive with just 930 kW pulling eight Mark 3 coaches.

In an InterCity 125, there is nearly 1,400 kW to accelerate the same number of similar coaches to 125 mph.

But these are small numbers compared to a four-car Class 755 train running on electrical power, which according to Stadler’s data sheet is 2,600 kW, which is 86% more power than an InterCity 125.

As there are two power-bogies each must be good for 1,300 kW.

Typical four-car electric Flirts seem to have around 2-3,000 kW, according to various Stadler data sheets.

Flirts seem to be seriously powerful trains and I can understand why some Norwegian Flirts are capable of 125 mph running. This is said in Wikipedia about the Norwegian Flirts.

All trains have five cars. However, in contrast to previous five-car FLIRTs they will have a third powered bogie giving them a maximum power output of 4,500 kW (6,000 hp) and a top speed of 200 km/h (120 mph).

If that extract is saying that each bogie can provide up to 1,500 kW, then Class 745 trains with four bogies have 6,000 kW.

If they were Class 755 train-sized bogies, then Class 745 trains, then the trains have 5,200 kW.

For comparison, an eleven-car Class 390/1 train has 5,950 kW.

With these figures, I feel it is reasonable to assume, that Class 745 trains, will accelerate to operating speed faster than the current forty-year-old BR stock.

  • They appear to have a lot more power, than the current trains.
  • Their aluminium bodies probably mean they weigh less, than the steel-bodies of the current trains.
  • Their aerodynamics are probably more advanced.
  • They probably have sophisticated technology that stops wheel slip, controls the train in a smooth manner and assists the driver.
  • The rolling dynamics will be no worse than that of the current trains.

Some conclusions can be drawn about the current trains and their operation.

  • A Class 90 locomotive with only 930 kW has sufficient power to keep an eight-car train running at 100 mph. It looks like the figure  is around 1.2 kWh per car per mile.
  • They must be in top condition.
  • The drivers probably know the route like the back of their hand and can coax the required performance from their ageing charges.

BR’s forty-year-old design must still be seriously good and the trains get the TLC they need.

Passing Stations At 100 mph

Diss, Stowmarket, Needham Market, Marks Tey, Kelvedon, Hatfield Peverel and Ingatestone stations were all passed within a few mph of 100 mph, with Maningtree and Colchester stations passed at around 85-90 mph.

Obviously, this must be allowed and not having to slow means that the speed is not degraded.

The only station where there was a substantial slowing was Chelmsford, where the train slowed to about 60 mph.

The Current Norwich-in-Ninety Services

These are the current ninety minutes services between Liverpool Street and Norwich.

  • 0900 – Norwich to Liverpool Street
  • 1100 – Liverpool Street to Norwich
  • 1700 – Norwich to Liverpool Street
  • 1900 – Liverpool Street to Norwich

Only one train is needed that starts and finishes in Norwich, where it is stabled overnight.

Serving The Intermediate Stations

Both the 1100 train to Norwich and the 1700 to Liverpool Street only stop at Ipswich.

But leaving a couple of minutes behind was another Class 90 locomotive/Mark 3 coach set stopping at more stations.

  • Going North, the train takes nineteen minutes longer, with stops at Colchester, Manningtree, Ipswich and Diss.
  • Going South, this train takes ten minutes longer, with stops at Diss, Stowmarket, Ipswich, Colchester and Stratford.

I suspect that when the Bombardier Class 720 trains have been delivered, these might be used for the stopping trains.

How Many Trains Will Be Needed?

It appears that the slower trains are currently timetabled to take between 111 and 115 minutes.

If a round trip can be done in four hours, then two trains per hour (tph), will require eight Class 745 trains.

As there are ten trains on order, this means the following.

  • Eight trains will be used to run the two tph stopping service.
  • One train will be needed for the Norwich-in-Ninety service.

This leaves one train as a spare or in maintenance.

Cromer And Back In A Day

In the four-and-a-half hours, I was in Norwich, I was able to take a train to Cromer, take a few pictures, have a quick lunch and then return to Norwich.

This is possible using the slower trains, but the fast trains can give you another hour in Norwich.

Obviously, this hour will be available for many journeys and must surely open up many possibilities for frequent travellers on the route.

How Reliable Is The Norwich-in-Ninety Service?

There have been twenty services in the first week of the service..

  • Fourteen have been on-time or a couple of minutes early.
  • Five have been under ten minutes late.
  • One was late by more than ten minutes.

That last train was twenty-two minutes late and I was on it, on the first Wednesday of the service.

I shall update this table, until I get bored with it!

Can The Timetable Be Changed?

The way the timetable is set out is an interesting solution to trying to be all things to all passengers.

  • There is a basic two tph service, which stops between London and Norwich according to a simple pattern.
  • Four services per day, with two in each direction, are delayed by two or three minutes.
  • The original departure times are taken by a fast train, that only stops at Ipswich.
  • These four departure times, are arranged, so that the services can be handled by a single fast train shuttling between Liverpool Street and Norwich
  • The fast train starts in Norwich at 0900 in the morning and returns to Norwich and its depot at 2030. The train can then have a good service after a hard day’s work!

Obviously, Greater Anglia have all the passenger data, so they have probably laid out a fast timetable, that will reflect current passenger numbers.

But as time goes on, this timetable can be augmented.

At present, they are using their express trains for both the two tph and the fast services.

These will be changed to Class 745 trains during the remainder of this year.

The venerable Class 90 locomotives and their Mark 3 coaches have blazed the trail and made everybody’s dream of Norwich-in-Ninety a reality, but now it is up to Greater Anglia’s new trains to fully develop the timetable.

  • If they are successful in attracting passengers more services will do Norwich in ninety and Ipswich in sixty.
  • The back-up stopping service running behind the fast train could be run by a new Class 720 train, which have a similar 100 mph operating speed.
  • Several services per day, using Class 755 trains, will be running between Lowestoft and London and augmenting the fast service between London and Ipswich.

Interestingly, as I left Norwich for Cromer, there was a Class 321 Renatus at Norwich station in Platform 2 Checking with Real Time Trains, this other relic from British Rail, but refurbished to a modern standard for passengers and performance, formed the 1400 express to London and arrived on time after seven stops.

It looks to me that Greater Anglia have a creditable back-stop, if there should be any unforeseen problems with the new trains.

But it also shows that the stopping service that follows the Norwich-in-Ninety service can be run by a 100 mph electric multiple unit.

This would surely release Class 745 trains to run more fast services.

An Improved Ipswich And Norwich Service

Greater Anglia have said that there will be three tph between London and Norwich and that one may or will be run the new Class 720 trains.

The only section of the Great Eastern Main Line, that won’t have four tph will be between Ipswich and Norwich. So could we see a 100 mph local service between two rivals.

Yesterday’s Class 321 Renatus did Norwich to Ipswich in forty-one minutes.

  • The route is fully-electrified.
  • Class 720 or Class 321 Renatus trains could be used.
  • Trains would stop at Diss, Stowmarket and Needham Market stations.
  • The rail line is not busy North of Stowmarket.
  • The bottleneck of Trowse bridge South of Norwich is to be replaced.

Running four tph between Ipswich and Norwich would be a lot more affordable, than improving the capacity on the mainly single-carriageway A140.

Would Faster Running Be Possible North Of Ipswich?

There are two major problems on the Great Eastern Main Line to the North of Ipswich.

  • Trowse Bridge to the South of Norwich.
  • Haughley Junction, where the Cambridge and Norwich routes divide to the North of Stowmarket.

Both projects have been kicked into the long grass more times than most, but it does look, that these two bottlenecks could be fixed in the next few years.

I also observed the following between Ipswich and Norwich.

  • The line wasn’t busy North of Stowmarket.
  • The train had no difficulty maintaining 100 mph.
  • The quality of the overhead electrification gantries might suggest a need for replacement.
  • There are some level crossings, that have no place on a 100 mph main line.

Would it be advantageous to update the line, so that higher speeds were possible?

I suspect that both the Class 745 and Class 720 trains could handle perhaps 110 mph with modifications, that are proven or planned with similar trains.

Conclusion

I had an exhilarating ride yesterday and it is a foretaste for the greatest improvement in transport for East Anglia in my lifetime.

The Norwich-In-Ninety Timetable

The Norwich-In-Ninety trains are now visible on the National Rail timetable.

London To Norwich

Norwich-In-Ninety trains leave London at 11:00 and 19:00!

The current times of the 11:00 train are as follows.

  • Liverpool Street – 11:00
  • Colchester – 11:46
  • Manningtree – 11:55
  • Ipswich – 12:07
  • Diss – 12:36
  • Norwich – 12:50

Those of the faster train are.

  • Liverpool Street – 11:00
  • Ipswich – 11:55
  • Norwich – 12:30

I can remember in the 1960s, the diesel service was advertised as two-hour two-stop between London amd Norwich.

Norwich To London

Norwich-In-Ninety trains leave Norwich at 09:00 and 17:00!

The current times of the 09:00 train are as follows.

  • Norwich – 09:00
  • Diss – 09:17
  • Stowmarket – 09:29
  • Ipswich – 09:41
  • Manningtree – 09:52
  • Colchester – 10:02
  • Chelmsford – 10:21
  • Stratford – 10:45
  • Liverpool Street – 10:55

Those of the faster train are.

  • Norwich – 09:00
  • Ipswich – 09:33
  • Liverpool Street- 10:30

Note that the current Southbound services are slower than those going North.

The Current Linespeed

For part of my trip back from Ipswich today, I was following the linespeed using the Speedview App on my phone.

  • Between Kelvedon and Hstfield Peverel the train averaged around 100 mph.
  • It then slowed to 60 mph through Chelmsford.
  • By Ingatestone, it was up to 90 mph, before slowing for 60 mph through Shenfield.
  • There seemed to be some checking from a slower train, but at places into Liverpool Street it was up to 80-90 mph.

The Norwich-In-Ninety improvements certainly seemed to have helped.

It certainly left me with the feeling that the elderly Class 90 locomotive and Mark 3 carriages could achieve Ipswich to Liverpool Street in around an hour.

The Future

These four services are probably just the start. These four services can probably be achieved with one train.

  • Leave Norwich at 09:00 and arrive in Liverpool Street at 10:30
  • Leave Liverpool Street at 11:00 and arrive in Norwich at 12:30
  • Leave Norwich at 17:00 and arrive in Liverpool Street at 18:30
  • Leave Liverpool Street at 19:00 and arrive in Norwich at 20:30

Although, Greater Anglia will be running the initial service with Class 755 trains, the company has ten Class 745 trains on order.

The only thing so far disclosed, is that the Liverpool Street and Norwich service will go to three trains per hour (tph).

It should also be said, that the design of the new trains and their power, should make station stops much faster.

But what pattern of stops will be performed by the three trains?
