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 810 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.

The trains will certainly get better.

£500m Fund To Restore Beeching Rail Cuts Goes Ahead Amid Criticism

The title of this post is the same as that of this article on the BBC.

This is the introductory paragraph.

A government fund is to be launched later to restore historic railway lines closed more than 50 years ago under the so-called Beeching cuts.

The two initial grants are for studies about reopening the Northumberland Line to Blyth and Ashington in the North East and to Fleetwood to the North of Blackpool.

Blyth And Ashington

Consider.

  • The tracks already exist.
  • There may still be some freight traffic on the route.
  • Connections to the Tyne and Wear Metro appear possible.
  • The Tyne and Wear Metro already shares tracks with other freight and passenger services.
  • New stations and probably new signalling will be needed.
  • The distance between the proposed Northern terminals and the connections with the Tyne and Wear Metro are under twenty miles, which could make battery operation easily possible.
  • The Tyne and Wear Metro is currently procuring a new fleet of trains.

I believe that these branches could be integrated into the Tyne and Wear Metro, providing that the new trains have the right specification.

Light rail vehicles like the Class 398 tram-trains being procured for the South Wales Metro should be able to run these services.

But other manufacturers might have better solutions!

Fleetwood Branch

This extension would need the following.

  • Restoration of the existing track between Poulton-le-Fylde and Fleetwood.
  • One or more new stations.
  • Probable resignalling.

In a simple installation, there is probably space to put a bay platform in Poulton-le-Fylde station, so that a shuttle service could be run to Fleetwood.

But services could also be extended to Preston.

Blackpool though has other rail problems like what are they going to do with the Blackpool South Line.

I believe Blackpool could use similar solutions on both the Blackpool South and Fleetwood Lines to create a bigger solution for the whole of the area.

Conclusion

It looks to me that the government has started with two schemes that are possible and where the track still exists.

It is to be hoped that the two studies come up with easy-to-build and fundable schemes, which are the first of many.

Raw Material For Southern’s Battery Trains

Porterbrook and Southern are proposing to convert a number of Class 377/3 trains to battery operation for the Uckfield Branch and the Marshlink Line, as I wrote about in Electroflex Battery EMU Plan To End Southern Diesel Operation.

This morning I took a ride in a ten-car Class 377 train formed by two three-car Class 377/3 units and one Class 377/4.

I will split my observations into various sections.

First Class

There is a small First Class section.

Is this really needed in a three-car train, considering that some franchises are going for one-class trains?

Gangways

On the Uckfield Branch and the Marshlink Line, I suspect that trains will work in multiple formations, so the gangway will be useful to allow passengers to pass between individual trains.

Interior

The interior is reasonably modern, as the trains were originally built in 2001-2002 and they meet all of the persons of reduced mobility legislation.

Multiple Working

The train I rode on consisted of three Class 377 Trains working together, so it would appear that six, nine and twelve car trains may be possible.

Tables And Cup-Holders

I would prefer full-size tables and perhaps these could be fitted, during the conversion, like they are in some Class 377 trains.

If not tables, then how about some cup-holders?

Universal Access Toilet

A universal-access toilet is fitted in the middle car.

Wi-Fi

Wi-fi appears to be fitted.

25 KVAC Operation

Although the trains are currently configured for operation on 750 VDC trird-rail electrification, these trains can be converted to run on 25 KVAC overhead electrification.

This would obviously mean that if the trains were no longer needed in Sussex, they could run anywhere else, where there is electrification.

Conclusion

They are a well-equipped train.

It would appear that very little will need to be done to the interior of the train in the conversion.

First may be downgraded to standard and I would fit full tables.

The operator would do what they wanted.

An Open Letter To Jamie Burles Of Greater Anglia

I will open by saying that this letter is not a complaint about your company, as you, like all your passengers and staff are just suffering collateral damage from the overwhelming incompetence of the real culprit.

I have been supporting Ipswich Town, off and on, since my parents retired to Felixstowe around 1960, when the next door neighbour used to take me to Portman Road.

In 2007, after living together in Suffolk for nearly forty years, my wife died of a squamous cell carcinoma of the heart, followed in 2010, by our son, who died at just thirty-seven of pancreatic cancer. I am coeliac and because of all this grief, I neglected my health, which caused me to have a serious stroke. Luckily, the only lasting problem, I suffered was a partial loss of vision, which meant I was unable to drive.

So I sold up in Suffolk and moved back to London, where I had been born in 1947.

For a couple of years, things went well coming out to Ipswich for matches by train. Typically, on a match day I would have a gluten-free lunch in London and catch the reliable 12:30 Norwich express and just arrive in my seat a few minutes before kick-off.

I should note, that there is only one reliable place for a coeliac like myself, who needs gluten-free food to eat in Ipswich and that is Pizza Express. But you can only eat so much pizza! I can get gluten-free sandwiches in Marks and Spencer, but as with the pizza, it means walking to the centre of town and at seventy-two now, that is not such an easy proposition, as it once was.

Over the last six years, the journey has got worse. The much longer journey  time on replacement buses, means I can’t eat properly or do any of the other things , I need to do in life on an average Saturday.

Consider.

  • Football may be important to me, but it is not that important.
  • I should say, that sometimes, I go via Cambridge, when replacement buses are in operation for a change, as I can have a meal in the city with friends or buy sandwiches in the Marks & Spencer in the station.
  • In all these years of disruption, it always seems that if Ipswich are at home on the Saturday, there would be a busification of the service, whereas on other Saturdays a full service operated.

When I first started coming out from London to see matches, there were quite a few supporters on the trains from London, including one guy in a wheel-chair. Over the years many seem to have fallen by the wayside, because of the constant disruption.

I had hoped that this season, Network Rail’s deplorable project management of the Great Eastern Main line, which often results in surprise closures,  would have been consigned to history.

But if ever, there have been more closures this season and the latest batch of nine closures starting on Saturday, are the last straw as far as I am concerned.

Saturday’s closure was particularly inconvenient, as Kings Cross was closed and the West Anglia Main Line was running a reduced service, so in the end, I had a late breakfast at St. Pancras and took Southeastern Highspeed to Ebbsfleet where a friend and fellow Ipswich season ticket holder, who lives nearby, gave me a lift  to the match. The home-to-home round trip , was actually almost as long, as that on the previous Saturday’s trip to Tranmere.

Looking at the next few Saturday Ipswich home games, I see the following.

  • Peterborough – 1st February – Normal service (?)
  • Burton Albion – 15th February – Buses
  • Oxford United – 22nd February – Buses
  • Coventry – 7th March – Buses
  • Portsmouth- 21th March – Buses
  • Rochdale – 18th April – Buses

I probably speak with more authority, than most, as the company I started in Ipswich; Metier Management Systems, is recognised as one of the companies, that changed project management completely, in the last three decades of the twentieth century. At times, half the major projects in the world were being planned and managed by software I wrote in a Suffolk attic.

I rate, Network Rail’s performance over the last few years in the wider UK, as one of the worst project management disasters I have known, alongside Berlin’s Brandenburg Airport, the legendary hospital built the wrong way round, and the Boeing 737 MAX.

Could High Speed Two Trains Serve Stoke-on-Trent?

The city of Stoke-on-Trent lobbied hard for High Speed Two to call, but it is going through closer to the West Coast Main Line, which is a few miles to the West.

Current Services

Stoke-on-Trent station is on the Stafford to Manchester branch of the West Coast Main Line.

It is served by two trains per hour (tph) between Euston and Manchester Piccadilly via Milton Keynes Central (1tph), Stoke-on-Trent, Macclesfield (1tph) and Stockport. The fastest journey time is one hour and 24 minutes.

Possible Routes Using High Speed Two

It should be noted that to serve Stafford on the West Coast Main Line, High Speed Two trains will use the West Coast Main Line, rather than High Speed Two between Lichfield and Crewe.

This map clipped from the High Speed Two web site, shows the two routes between Lichfield and Crewe.

Note.

  1. The straighter route is the new High Speed Two route.
  2. The bendy route is the West Coast Main Line.
  3. The two routes split to the North of the city of Lichfield in the South-East corner of the map.
  4. Stafford can be seen between the two routes.
  5. Stoke-on-Trent can be seen to the North-East of the routes.
  6. The new route through Crewe station is shown in orange.

To give an idea of scale, the West Coast Main Line is about forty miles long between the two junctions at Lichfield and Crewe.

Possible Ways High Speed Two Could Serve Stoke-on-Trent Station

There are several ways that High Speed Two trains can serve Stoke-on-Trent station.

London Euston And Stoke-on-Trent Direct

The simplest way is to run a direct service between London Euston and Stoke-on-Trent

  • It would use High Speed Two from Euston to Lichfield, where it would take the Trent Valley Line.
  • It would proceed to Stoke-on-Trent via Rugeley Trent Valley and Stone.

I estimate that the service would take one hour and two minutes.

The service could either turnback at Stoke-on-Trent or go on to Crewe, Manchester or some other convenient terminus.

Manchester services might even call at Macclesfield and Stockport, as the current services do now!

Times between London and Manchester by various routes could be.

  • Current via Stoke-on-Trent, Macclesfield and Stockport – Two hours and seven minutes.
  • Planned using High Speed Two – One hour and seven minutes.
  • High Speed Two and current route to Manchester – One hour and forty-one minutes

Manchester will get three tph from London and one from Birmingham, so perhaps one of the four services should go via Stoke-in-Trent.

‘Total Loss’ Feared After Fire Reportedly Damages Eviation Alice Electric Plane Prototype

Could The Northern Section Of The Bakerloo Line And The Watford DC Line Be Combined?

The Bakerloo and Watford DC Lines to the North of Queen’s Park station annoy me.

There are two very different classes of trains.

Which are different sizes and ideally need different platform heights for step-free access between train and platform.

Often, you need to step up and down into the trains.

The pictures show a typical steps on Bakerloo Line and Class 710 trains.

They give a new meaning to Mind The Gap.

It would be so much easier, for passengers in wheelchairs or those pushing buggies or trailing heavy cases for there to be no step between train and platform.

I once remarked to a station guy, not in the first flush of youth, as he manhandled a ramp into place, that what he was doing must be the worst part of his job. He smiled and agreed.

Surely in this day and age, we can create a railway, where everything is as efficient as possible.

These are a few of my thoughts.

Could The Two Lines Be Run By A Unified Fleet Of Trains?

If the two lines were to be run using the same trains, this would give advantages.

  • All trains could be maintained together.
  • Platform-to-train access would be much easier to make step-free.
  • Staff would only deal with one type of train.
  • A certain amount of automatic train control could be used to increase frequencies.

Obviously, a National Rail-size train couldn’t use the Bakerloo Line tunnels, but a train built for the Underground could use the current Watford DC Line into Euston.

Siemens are designing a New Tube For London and this will be used on the Bakerloo Line.

I suspect, that they could design a train that would easily run into Euston.

Would An Underground Train Provide Enough Capacity Into Euston?

The current trains on both lines have the following capacity and length.

  • The 1972 Stock on the Bakerloo Line are 113 metres long and have a capacity of 851 passengers
  • The Class 710 trains on the Watford DC Line are 82 metres long and have a capacity of 678 passengers.

Now there’s a surprise! The smaller Underground trains hold more passengers.

This picture shows the spare platform length at Euston, after a Class 710 train has just arrived.

I don’t think capacity or platform length will be a problem!

What Would Be The Frequency Into Euston?

Consider.

  • The current Watford DC Line service into Euston uses a double-track line terminating in Platform 9 at Euston station.
  • The service frequency on this route, has recently been increased from three trains per hour (tph) to four tph.
  • The Overground is soon to start to run six tph on routes with a similar track layout.

I believe that a six tph service could be run between Euston and Watford Junction stations.

What Would Be The Frequency In The Bakerloo Line Tunnel To Elephant & Castle And Lewisham?

Note that I’m assuming an extended Bakerloo Line runs to Lewisham, although, it could run to Hayes station.

Dear Old Vicky (aka the Victoria Line) handles a train every hundred seconds or thirty-six tph.

I can’t see any reason, why all parts of the Watford Junction to Lewisham route can’t be designed to handle this frequency.

If six tph went to Euston, then this would mean the service South of Queen’s Park station would be as follows.

  • Up to thirty tph or a train every two minutes between Queen’s Park and Lewisham stations.
  • It would connect the National Rail stations of Paddington, Marylebone, Charing Cross, Waterloo, Elephant & Castle, New Cross Gate and Lewisham.
  • A high capacity pedestrian link to Crossrail at Paddington, will be ready to open with Crossrail.
  • Connections to the Central, Circle, District, Hammersmith & City, Metropolitan, Northern, Piccadilly and Victoria Lines of the Underground.
  • Oxford Circus would have a high-capacity cross-platform interchange between the Bakerloo and Victoria Lines, both running in excess of thirty tph.

It would be a much needed capacity upgrade to the Underground.

Would Stations On The Combined Line Be Made Step-Free?

The combined route will have a total of 34 existing stations and four new stations.

I suspect the new stations will be step-free.

Of the existing stations, the following are fully or partially step-free.

  • Watford Junction
  • Bushey
  • Carpenders Park
  • Harrow & Wealdstone
  • Wembley Central
  • Willesden Junction
  • Queen’s Park – Scheduled to be made step-free.
  • Paddington – Will be step-free, when Crossrail opens.

The Bakerloo Line must be one of the worst lines for step-free access on the London Underground.

But then it has some of the oldest and least-capable trains and has been neglected for decades.

The station most in need of step-free access is probably Oxford Circus, where the Bakerloo and Victoria Lines have a cross-platform step-free interchange.

I lay out ideas for this station in Thoughts On Step-Free Access At Oxford Circus Station.

Upgrading The Lines

I think that Transport for London have a unique opportunity with the upgrading of the Bakerloo Line to Extension From upgrade the line as a series of separate projects, phased to be delivered in a continuous stream, rather than as one big launch, which was tried and failed with Crossrail.

Extension From Elephant & Castle To Lewisham Or Hayes

This project can be built independently, just like the Battersea Power Station Extension of The Northern Line. I detailed the latest thinking on this extension in TfL Moots Bakerloo Line To Hayes.

  • It is the only project that needs substantial tunnelling.
  • It probably needs a depot to be relocated.
  • Lewisham station would need some rebuilding.
  • It would need more trains to be delivered before it opens.

It could even be the last project to be delivered, which would allow time for the trains.

Use Of A Bi-Mode Class 755 Train On The Sudbury Branch Line

I took these pictures today on a visit to the Sudbury Branch Line in Suffolk.

The two stations shown are Marks Tey, where the branch joins the Great Eastern Main Line and Sudbury, which is the Western terminus of the branch.

Both stations have short platforms.

To simplify this description, I will identify the four cars of the Class 755 train as follows.

  • Driver East Car – Driver car with passengers on the Marks Tey end of the train.
  • Passenger Car – The passenger car, which also has the bike space and the Universal Access Toilet.
  • PowerPack – The smaller car that powers the train.
  • Driver West Car – Driver car with passengers on the Sudbury end of the train.

This Google Map shows Marks Tey station.

The short and gently curving, Sudbury Branch Line platform is on the North side of the station.

To make it easy for passengers to get in and out of the train, Greater Anglia seem to have devised a cunning plan.

  • The Class 755 trains run with the end with the Driver East and Passenger Cars are towards Marks Tey and Colchester stations.
  • The driver stops the train in the station, so that the two passenger cars, are in the same place as a two-car diesel multiple unit, like a Class 156 train, would be.
  • The two pairs of wide double doors and the level step-free access, encourage passengers to enter the train.
  • Interestingly, the PowerPack Car of the train is at the narrowest part of the platform and is this deliberate to encourage passengers to enter through the doors facing them on the platform.
  • The Driver West Car doesn’t come into the platform.
  • At busy times, when the Driver West Car will need to be used, passengers will walk through the PowerPack Car.
  • Bicycles can be wheeled between the platform and the space in the Passenger Car.

The method of operation has avoided any expensive lengthening of the short and curvy platform.

This second Google Map shows Sudbury station.

At least the single platform is straight.

A similar procedure is used at Sudbury station to that at Marks Tey.

  • The driver stops the train in the station, so that the Driver West and Passenger Cars either side of the PowerPack Car are in the station.
  • Passengers have two sets of doors and level access to get into and out of the train.
  • Bicycles can be wheeled between the platform and the space in the Passenger Car.
  • There is no direct access to the Driver West Car at the Marks Tey end of the train, but passengers can walk through the train.

Lengthening of the platform is not necessary.

Important Routes With Few Passengers

Suppose you have a route that at certain times of the day needs a three-car train, but at other times two-cars or even only one car.

I can think of the case of a large industrial site like a nuclear facility or power station, that has lots of passengers, when people are going to and from work and students are going to and from school and college, but at other times of the day, passenger numbers are low.

The conductor indicated to me, that the design of the train allows the doors on the PowerPack to be locked, thus restricting movement.

This could save operating costs if thought out properly.

Wheelchair Passengers To And From Sudbury

The conductor indicated that this was a problem for some directions.

  • London to Sudbury  is just a walk or push between platforms.
  • Sudbury to Ipswich and Norwich is just a walk or push between platforms.
  • Sudbury to London is take a train to Colchester from Marks Tey and use the lifts to change direction for London.
  • Ipswich and Norwich to Sudbury is take a train to Witham and use the lifts to change direction for Marks Tey.

The local MP is Pritti Patel and she has been pushing hard for a step-free bridge with lifts, which would solve the problem.

Sudbury And Colchester Town

Greater Anglia have proposed that the Sudbury service be extended to Colchester Town station.

There may be problems running on the busy Great Eastern Main Line between Marks Tey and Colchester, but at least there appears to be a freight loop just to the North of Marks Tey, on the London-bound track.

Some things would help.

  • Redesign of the junction to allow a faster turnout.
  • The extra power of the Class 755 trains.
  • Electrification of Platform 3 at Marks Tey station.
  • Full digital in-cab signalling on the Great Eastern Main Line.

It might even be worthwhile putting in a simple flyover for Sudbury-bound trains.

Could Battery Power Be Used On The Sudbury Branch Line?

Class 755 trains have been designed, so that diesel engines in the ~PowerPack Car can be replaced with batteries, which can be charged from electrification.

If and when a suitable battery module is developed, then it could just be slotted in.

Some form of charging would be needed and the proposal to change the service into s Sudbury and Colchester Town service, would allow the trains to be charged on the main line.

The German Solution

I can’t help feeling that the Germans or the Welsh would use a different solution.

In Could There Be A Tram-Train Between Ipswich And Felixstowe?, I discuss the East-West Rail Link’s idea of running tram-trains between Ipswich and Felixstowe.

  • It would have a frequency of four trains per hour.
  • It would probably start in the forecourt of Ipswich station.
  • It could either go to Felixstowe station or perhaps through the High Street and down to the Sea Front.
  • It would go via Portman Road, Ipswich Town Centre, Ipswich Hospital, before joining the Felixstowe Branch Line to the East of the town.

The reason for this proposal, is to get more freight trains into the Port of Felixstowe.

Now look at this Google Map of North Colchester.

Note.

  • Colchester station in the middle of the map on the Great Eastern Main Line, which runs East-West.
  • A junction to the East of the station, where the lines from Colchester Town, Clacton and Walton join the Great Eastern Main Line.
  • Colchester Hospital at the top of the map.

Without doubt,, the Germans would create a tram-train network based on Colchester station.

  • Sudbury and Marks Tey could be served in the West, by perhaps building a third track alongside the Great Eastern Main Line
  • Marks Tey and Sudbury would be on battery power.
  • Colchester Hospital and perhaps the football ground and a Park-and-Ride could be served in the North, by adding tracks to the junction East of Colchester.
  • Colchester Town could be served in the South, using the existing tracks.

The network would certainly connect a lot of important places to the main station.

  • It would improve access to Colchester Hospital.
  • It would solve the step-free problem at Marks Tey.
  • It could open up much needed new housing developments.

With 100 mph tram-trains or trains able to work as trams, it could reach places using the various routes in the area, like Clacton, Harwich and Walton.

Stadler have already designed 100 mph diesel trains, that work in Zwickau in Germany, alongside and share tracks with the city’s trams.

It seems that if you have a specification, Stadler will make it.

Conclusion

Greater Anglia are going to have fun with these trains.

Their level access is liked by passengers.

The short car length, allows the trains to call in curvy platforms.

Green Hydrogen ‘Cheaper Than Unabated Fossil-Fuel H2 by 2030’: Hydrogen Council

The title of this post is the same as this article on Recharge.

This is the introductory paragraph.

Clean hydrogen derived from renewable energy will be cost-competitive with highly polluting grey hydrogen within 5-10 years, says new report.

Points about or contained in the article.

  • The report is by respected consultants; McKinsey.
  • Currently grey hydrogen produced by steam reforming produces 9-12 tonnes of carbon dioxide for every tonne of hydrogen produced, at a cost of $1.5 per Kg.
  • Green hydrogen produced by electrolysis using renewable energy, has a cost of $6 per Kg.
  • In certain parts of the world, like Chile, Australia and Saudi Arabia, with strong winds and sunshine, prices for green hydrogen could drop to $1.20 per Kg.
  • The article also talks about blue hydrogen, where the carbon dioxide is capyured and stored.

I suggest you read the article.

If you can’t be bothered just digest this paragraph.

The report adds that the blue and green hydrogen will be the cheapest options for many types of transport by 2030 — outperforming fossil fuels and battery power. These include long-distance buses, heavy- and medium-duty trucks, taxi fleets, regional trains and large passenger vehicles such as SUVs.

I can also envisage hydrogen being shipped around the world from the three countries named and others to countries like Germany,China and Japan, that need to decarbonise, in massive ships. Powered by hydrogen of course.

Electroflex Battery EMU Plan To End Southern Diesel Operation

The title of this post is the same as this article on Railway Gazette.

This is the introductory paragraph.

An electric multiple-unit is to be equipped with batteries for ’first of a kind’ testing which could lead to the end of diesel traction on the Ashford – Hastings and Oxted – Uckfield routes.

The train to be converted is a Class 377/3 train.

  • These are three car trains.
  • There are twenty-nine of these trains.
  • They have 176 seats.
  • They were built in 2001/2002.

The article gives some details of the conversion.

  • The trains would have a range of 60 km.
  • They could be charged in eight minutes.
  • There would be an emergency mode to keep systems running for an hour. Sounds very much like a Class 345 train.
  • Between twenty-five and thirty trains would need to be converted to replace all the diesel trains. Twenty-nine?

The article also says that the General Election has delayed the sign-off.

In August 2018, I wrote Battery Trains On The Uckfield Branch. I was proposing Aventras as they are obviously a more efficient train. The article details a lot of the mathematics involved.

Some Observations

These are my observations on various topics.

Uckfield Branch

The section without electrification on the Uckfield Branch is forty kilometres long.

A train with a full battery can go from one end to the other.

As the train takes eleven minutes to turn round at Uckfield, there is enough time to recharge the batteries.

Would the route be run by three Class 377/3 trains, running as a nine car unit?

Trains would be charged en route between London Bridge and Hurst Green stations and if required at Uckfield.

Would charging at Uckfield be a length of third-rail electrification in the long platform?

It sounds that there is a feasible solution for Uckfield.

Capacity On The Uckfield Branch

Consider

  • Three Class 377/3 trains running together have a capacity of 528 seats.
  • Five Class 171 trains running together have a capacity of 535 seats.

I think that the capacity would be enough.

Number Of Trains Needed For The Uckfield Branch

The round trip on this route takes three hours, so to run an hourly service will need three nine-car trains or nine three-car trains in total. Two trains per hour (tph) will need a total of eighteen trains.

The Marshlink Line

The Marshlink Line is also forty kilometres long and both ends are already electrified.

Services on the route terminate at Eastbourne in the West and Ashford International in the East.

As the route between Ore and Eastbourne stations is fully electrified, charging at the Western end of the route, will be en route and trains will arrive at Ore with a full battery.

The platform at Ashford International is electrified using third rail and there is adequate time in the turnround to charge the battery, so that it leaves Ashford full.

Train Length On The Marshlink Line

There are some shorter platforms across the Romney Marsh and these may restrict the length of train that can be used. But as they are generally two-car trains at present, even a three-car train is an over fifty percent increase in capacity.

I suspect Southern would probably want to run six-car trains between Ashford and Eastbourne.

Number Of Trains Needed for the Marshlink Line

The round trip on the route takes three hours, so to run an hourly service will need three trains. If they were six cars, then six three-car trains would be needed.

Total Number Of Trains Needed For Both Routes

If nine-car half-hourly trains are run on the Uckfield Branch and hourly six-car trains on the Marshlink, this will need twenty-four trains. As there are twenty-nine trains available for conversion, this would appear to be very convenient.

The article stated that between twenty-five and thirty would need to be converted. So there is probably enough trains to allow for a spare and a couple in maintenance.

What Size Battery Will Be Needed On Each Train?

I will now attempt to estimate the size of battery needed for the train.

The Kinetic Energy Of A Full Train

This is important for two reasons.

  • When a train accelerates from rest, the battery must have enough stored energy to bring that train to the operating speed.
  • When a battery train brakes, the energy of the train, recovered by regenerative braking, must be capable of being stored in the battery.

Note that regenerative braking loses perhaps ten to fifteen percent of the energy at each station stop.

This is the calculation for the kinetic energy.

  • The weight of the empty train is 133.1 tonnes
  • The train has around two hundred passengers, who each weigh 90 kilograms with baggage, bikes and buggies.
  • This adds a surprising 18 tonnes.
  • The total train weight 151.1 tonnes.

The kinetic energy of the train can be calculated for various speeds using Omni’s Kinetic Energy Calculator.

  • 30 mph – 3.8 kWh
  • 40 mph – 6.7 kWh
  • 50 mph – 10.5 kWh
  • 60 mph – 15.1 kWh
  • 70 mph – 20.6 kWh
  • 100 mph – 42.0 kWh

I have included the last figure, as that is the cruising speed of the train.

When I first calculated train energy figures, I thought these figures were too low, when you consider that according to Ovo Energy, the average electricity consumption of a UK dwelling is about 10 kWh.

Regenerative Braking Losses

If we assume that at each stop fifteen percent of the energy of the train is not recovered, then for a train travelling at 60 mph, then 0.15 * 15.1 or 2.3 kWh will be lost at each stop.

The Uckfield Branch has seven intermediate stops so will lose 15.9 kWh under braking and this will need to be in the battery at the start of the electrification-free run.

The Marshlink Line has six intermediate stops, so will lose 13.6 kWh.

Energy Needed To Maintain Speed And Run The Train

A train needs power for the following purposes.

  • Overcome friction and aerodynamic loses, whilst travelling at the operating speed. When you are riding a bicycle, you need more energy to accelerate, but then you need to keep pedalling to maintain speed.
  • To power the various electrical systems on the train, like air-conditioning, doors, lights and toilets.
  • To power the control systems of the train.

It is generally accepted, that a simple way of expressing the power needed by the train is between 2 and 5 kWh per vehicle-mile.

So power needed by a three-car Class 377 train over the twenty-five miles of both routes will be.

  • 2 kWh per vehicle-mile – 150 kWh
  • 3 kWh per vehicle-mile – 225 kWh
  • 4 kWh per vehicle-mile – 300 kWh
  • 5 kWh per vehicle-mile – 375 kWh

This energy will be taken from the battery.

An Estimate Of Energy Used And Battery Size Required

This calculation is for the Uckfield Branch and I am assuming the following.

  • A cruising speed of 60 mph.
  • Regenerative braking is 85 % efficient.
  • 3 kWh per vehicle mile is used in the cruise.

Energy use will be as follows.

  • Initial acceleration to cruising speed – 15.1 kWh
  • Regeneration losses – 7 * 0.15 * 15.1 -15.9 kWh
  • Energy needed to run train – 225 kWh

This gives a total of 256 kWh

There will also need to be a reserve to cater for.

  • Trains stopping because of a problem like cows on the line.
  • Recovery of the train to the nearest station.

The article talked about an emergency mode of an hour.

I wonder if a battery of between three hundred and four hundred kWh would be sufficient.

Note that Vivarail find space for 424 kWh in the two-car train, I wrote about in Battery Class 230 Train Demonstration At Bo’ness And Kinneil Railway.

I have various Excel spreadsheets that can model various scenarios.

I’m sure Bombardier have much better information, than I do and can do better than this crude estimate.

Conclusion

This could be the first of many conversions of existing Bombardier Electrostars and Siemens Desiros to battery-electric operation.
