Digital Signalling Work Outlined By Network Rail For Northern City Line
The title of this post, is the same as that of this article on Rail Business Daily.
This is the first paragraph.
Network Rail has detailed work due to be delivered on the Northern City Line to Moorgate.
I use this line regularly and I believe that with digital signalling the Northern City Line could see a large increase in frequency.
Currently, the service from Moorgate is as follows.
- 4 tph to Welwyn Garden City via Potters Bar
- 4 tph to Hertford North of which 2 tph extending to Watton-at-Stone and 1tph of those continuing to Stevenage.
Note.
- tph is trains per hour.
- Although the service is reduced from that shown, because of the pandemic and lower passenger demand.
But eight tph means a train every seven minutes and thirty seconds.
If you look at London’s high frequency lines, they have or will have passenger frequencies as follows.
- Crossrail – 24 tph on dedicated tracks with digital signalling.
- East London Line – 16 tph on dedicated tracks.
- North London Line – 8 tph on tracks shared with freight trains.
- Thameslink – 24 tph on dedicated tracks with digital signalling.
Note.
- The East London Line is planned to go to 20 tph with two extra tph to Clapham Junction and Crystal Palace.
- 20 tph means a headway between trains of three minutes.
- 24 tph means a headway between trains of two minutes and thirty seconds.
It should also be noted that the Victoria Line runs upwards of thirty tph on a fully digitally-signalled line.
What Level Of Service Would Be Possible?
These are my thoughts on various aspects of the Northern City Line.
How Many Trains Could Be Handled Between Finsbury Park And Moorgate?
This section of track is a simple double-track with a diamond crossing to the North of the two platforms at Moorgate, so that trains can use either platform.
This layout is used at Brixton and Walthamstow Central on the Victoria Line and Battersea Power Station on the Northern Line to name just three of many.
So I suspect that the track layout at the terminus at Moorgate can handle well-upwards of twenty tph.
The new Class 717 trains that run into Moorgate have an operating speed of 85 mph, which is faster than the previous Class 313 trains, which appear to have run at 30 mph South of Drayton Park.
I suspect that eventually twenty or even twenty-four tph will be possible on a digitally-signalled route between Finsbury Park and Moorgate.
But in the interim, sixteen tph would be a good compromise.
How Many Trains Could Be Handled On The Current Routes?
Currently, four tph use the both the Welwyn Garden City and the Hertford East/Stevenage routes.
I am fairly sure that both routes could handle eight tph, with the only proviso, that there is enough terminal capacity to turn the trains.
Looking at the layout of Welwyn Garden City station, I am certain that it could be modified to be able to handle eight tph.
I would hope that the new platform at Stevenage station, built to handle trains to and from Moorgate, can cater for four tph. As there are turnback platforms at Gordon Hill and Hertford North stations, I’m sure the other four tph could be handled.
The Piccadilly Line And The City of London
It has always been difficult to get between the Northern section of the Piccadilly Line and the City of London.
In the 1960s, I used to use my bicycle. By public transport, you generally had to use the bus or the 641 trolley bus to Moorgate.
With the improvement of the Northern City Line and Finsbury Park station, the fastest route to Moorgate is probably to change between the Piccadilly and Northern City Lines at Finsbury Park station.
Increasing the frequency of Northern City Line services between Finsbury Park and Moorgate would create a high-capacity route to the City for those commuting from the Northern section of the Piccadilly Line.
The Piccadilly Line And Crossrail
There is no connection between the Piccadilly Line and Crossrail.
A trip between Oakwood and Canary Wharf would be difficult.
As with getting to the City of London, the improvement of the Northern City Line and Finsbury Park station offers a route to Crossrail.
Oakwood and Canary Wharf would probably be done with changes at Finsbury Park and Moorgate.
The Victoria Line And The City of London
There is a cross-platform interchange at Highbury & Islington station between the Victoria and Northern City Lines.
With an increased frequency of Northern City Line services between Finsbury Park and Moorgate, I would expect that more people would use this route.
The Victoria Line And Crossrail
There is no connection between the Victoria Line and Crossrail.
The easiest route will be to take the route in the previous section and join Crossrail at Moorgate.
Conclusion
It does look that with the current routes sixteen tph to and from Moorgate could be a practical limit.
But that would still be a train every three minutes and forty-five seconds between Finsbury Park and Moorgate.
This increased frequency could be needed to create a high capacity link between the Northern sections of the Piccadilly and Victoria Lines and the City of London and Crossrail.
KEPSA Signs Large-Scale Green Energy Projects MoU In Kenya
The title of this post, is the same as that of this article on ESI Africa.
This is the first paragraph.
The Kenya Private Sector Alliance (KEPSA) has signed a Memorandum of Understanding (MoU) with green energy company Fortescue Future Industries (FFI) to help facilitate its members participation in new large scale green energy projects in Kenya.
FFI are planning a possible green hydrogen and green ammonia facility in the country, that will use renewable energy.
Andrew Forrest is building up the air miles again.
Is The Alstom Hydrogen Train Powered By A Fuel Cell?
In Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet, I mentioned that Alstom’s Hydrogen Aventra could be powered by either a small gas turbine or a fuel cell or cells, but I didn’t plump for one or the other. I said this.
If you look at the proportions of the Alstom hydrogen train and the pictures of Class 710 trains, I feel that the Alstom train could have the longer twenty-four metre cars.
It may be a tight fit compared to creating the Alstom Coradia iLint hydrogen train, but I would feel it is possible to install a fuel cell or cells, the required cooling and the hydrogen tanks, having seen cutaway drawings of hydrogen-powered double-deck buses on the Wrightbus web site.
Interestingly, the Alstom press release doesn’t mention fuel cells, so could the train be powered by a small gas turbine?
I think it is unlikely, but it is technically feasible.
I had forgotten one important factor. Both the Aventra factory and Rolls-Royce are in Derby and I know from talking to a retired British Rail engineer, that there is a lot of contact between the two companies at an informal level.
Rolls-Royce have published this picture of their beer keg-sized generator.
Would it need the cooling system, which appears to be needed with a fuel-cell?
The Rolls-Royce Advantage
There would surely be advantages in using a Rolls-Royce gas turbine to power the train.
- Having a Rolls-Royce power unit must help sales of your plane or train.
- There is the Derby connection.
- Alstom already deal with Rolls-Royce subsidiary; MTU for diesel engines for freight locomotives.
Could we be seeing a hydrogen multiple unit powered by a gas turbine?
‘Spirit of Innovation’ Stakes Claim To Be The World’s Fastest All-Electric Vehicle
The title of this post is the same as that of this press release on the Rolls-Royce web site.
This is the first paragraph.
We believe our all-electric ‘Spirit of Innovation’ aircraft is the world’s fastest all-electric aircraft, setting three new world records. We have submitted data to the Fédération Aéronautique Internationale (FAI) – the World Air Sports Federation who control and certify world aeronautical and astronautical records – that at 15:45 (GMT) on 16 November 2021, the aircraft reached a top speed of 555.9 km/h (345.4 mph) over 3 kilometres, smashing the existing record by 213.04 km/h (132mph). In further runs at the UK Ministry of Defence’s Boscombe Down experimental aircraft testing site, the aircraft achieved 532.1km/h (330 mph) over 15 kilometres – 292.8km/h (182mph) faster than the previous record – and broke the fastest time to climb to 3000 metres by 60 seconds with a time of 202 seconds, according to our data. We hope that the FAI will certify and officially confirm the achievements of the team in the near future.
Rolls-Royce also claim that the maximum speed achieved of 387.4 mph make it the world’s fastest all-electric vehicle.
To put that speed into perspective, it is faster than a Mark V Spitfire, which was powered by a legendary Rolls-Royce Merlin engine. These aircraft were powered by a Merlin 45 engine that generated 1074kW.
By comparison the Spirit of Innovation has a maximum power of just 400 kW.
Why Do It?
This paragraph from the press release gives an explanation.
As well as a stunning technical achievement, the project and world record runs provided important data for our future electric power and propulsion systems for all-electric urban air mobility and hybrid-electric commuter aircraft. The characteristics that ‘air-taxis’ require from batteries, for instance, are very similar to what was developed for the ‘Spirit of Innovation’.
I’ll go with that, as Rolls-Royce seem to be associated with several electric aviation projects.
But I can’t help feeling that there are parallels with the 1930s, when Supermarine and Rolls-Royce teamed up to produce the Supermarine S 6B, that won the Schneider Trophy outright in 1931. It is generally accepted that the knowledge gained at the time helped to design the Spitfire and the Merlin engine.
Whitelee Green Hydrogen Facility To Power Public Transport
The title of this post, is the same as that of this article on the BBC.
Some points from the article.
- It will be the country’s largest electrolyser. Is that Scotland or the UK?
- The facility is being built by Scottish Power, ITM Power and BOC.
- Friends of the Earth think it’s wrong and the electricity should be used immediately.
In ScottishPower’s Green Hydrogen Project Looks To Build UK’s Largest Electrolyser, the title says that the Whitelee project will be the UK’s largest electrolyser.
Could The Standedge Tunnels Be Part Of A High Speed Line?
This article on Rail Technology Magazine is entitled Warrington Borough Council React To Integrated Rail Plan, where this is said about improvements between Liverpool and Manchester via Warrington.
One such promise is the delivery of a new high-speed line between Warrington, Manchester and Marsden as part of NPR.
The IRP will also introduce a fully electrified upgraded line between Liverpool and Warrington as part of NPR.
Note NPR is Northern Powerhouse Rail.
Where Is Marsden?
This Google Map shows the rail line between the Standedge Tunnels and Marsden station.
Note.
- Standedge Tunnels and the Visitor Centre in the West.
- Marsden station in the South-East corner of the map.
- The railway between them is the Huddersfield Line.
- The distance between Marsden station and the Eastern Portals of the Standedge Tunnels is about a mile.
Huddersfield station is seven miles to the East of Marsden station.
The Eastern End Of The Standedge Tunnels
This Google Map shows the Eastern end of the Standedge tunnels.
Note.
- This is a 3D image tilted to give a possibly better view.
- Only a double-track railway and a canal tunnel are in daily use.
- There are two other disused but intact single-track rail tunnels.
- I suspect that the Tunnel End Reservoir keeps the canal water at the right level.
It looks to me that the Standedge Tunnels will be part of the proposed high speed route.
Greenfield Station
Greenfield station is to the West of the Western portal of the Standedge tunnels.
The distance between Greenfield and Marsden stations is six miles.
The Standedge Tunnels
Wikipedia has a very comprehensive description of the canal tunnel and the three rail tunnels that form the Standedge tunnels complex.
These are points from the entry.
- The canal tunnel is the oldest and was opened in 1811.
- The two single-track rail tunnels were opened in 1848 and 1871
- The double-track rail tunnel opened in 1894.
- The rail tunnels were all built using the canal tunnel for access.
- All the tunnels are parallel to each other.
- The tunnels are level.
- All tunnels appear to be connected together with cross passages.
- For safety reasons some diesel-powered boats are towed through the canal tunnel using electric tugs.
- The railway tunnels were the only level section of the route and were fitted with water troughs for steam engines.
- Drainage of the rail tunnels appears to be good, with water draining into the canal.
- Only the 1894 tunnel is in use by trains, but all three rail tunnels are maintained.
- The 1848 tunnel can be used for emergency access and is accessible to fire engines and ambulances.
The complex appears to be a masterpiece of nineteenth century engineering.
There are several factors that could enable the conversion of the rail tunnels into a high-capacity modern railway with speeds up to at least 100 mph.
- The tunnels are level.
- The tunnels are well-drained.
- The access to the tunnels is good.
- Slab track, which allows higher speeds could be installed in the tunnels, as it was in the Bowshank Tunnel on the Borders Railway.
But the biggest factor could be the possibility of using battery-electric trains to avoid electrification of the main lines, which as now would probably be in the double-track tunnel.
This Hitachi infographic describes their Intercity Battery Hybrid Train, which is based on a Class 802 train and they are developing in partnership with TransPennine Express.
Note.
- Greenfield and Marsden stations are only six miles apart.
- The tunnels are only a few metres longer than 5000 metres.
- The train may only be able to cover 5 km now, but I believe this could be increased.
I also wonder, if the electrification on either side could get as close to the tunnel as possible.
This would enable trains to drop pantograph at speed and switch to battery power a few metres from the tunnel and get to the other side using a mix of battery-power and kinetic energy. Once under the wires at the other side of the tunnel and they had slowed to a safe speed at which they could raise the pantograph, it would be raised and trains would continue using the electrification.
The operating speed would probably be determined by any curves at the ends of the straight and level tunnel.
This method of operation may be OK for expresses, but what about other passenger and freight trains?
I wonder, if it would be possible to put a third track in one of the other rail tunnels.
- Slab-track would probably be installed.
- This third track could be electrified.
- It would be signalled to allow bi-directional running.
This by-pass tunnel could keep the main lines free for the expresses.
Conclusion
I am fairly sure that the Standedge Tunnels could be incorporated in a high speed line.
The Great Bus Robbery
Transport for London (TfL) obviously don’t like people where I live in the Northern part of De Beauvoir Town in the London Borough of Hackney.
When I moved here, ten years ago there were six bus routes that passed through the traffic lights where the Balls Pond Road (It is not a made-up-name from Round The Horne) and Southgate Road/Mildmay Park meet.
- 21 – Newington Green and Lewisham Shopping Centre
- 30 – Marble Arch and Hackney Wick (From the sublime to the ridiculous?)
- 38 – Victoria station and the romantic Clapton Pond
- 56 – Bart’s Hospital and Whipps Cross (You’d be cross, if you’d been whipped!)
- 141 – London Bridge Station and Palmers Green North Circular Road (Surely, another romantic destination!)
- 277 – Highbury & Islington Station and Crossharbour
Note.
- We had two bus routes to and from Highbury & Islington station for Dear Old Vicky!
- We had two bus routes to and from Moorgate, Bank and the City of London.
- We had four bus routes to and from Dalston Junction station and the cultural attractions of Hackney Central.
- We had a direct bus to Canary Wharf.
TfL looked at the name of the district and thought the posh French name, meant we were all had expensive vehicles or Hackney carriages and said we had too many buses.
So in June 2018, the 277 bus was cut back to Dalston Junction station and TfL promised that the frequency of the 30 bus would be increased. We’re still waiting for extra services.
Now, if you want to go to Highbury & Islington station, according to TfL’s Journey Planner, it’s often quicker to take a 38 or 56 bus to Essex Road station and take a train.
To make matters worse the 30 bus route now has cheap and nasty Egyptian-built buses with more steps than Russia. All buses should have flat floors like the New Routemasters.
What is TfL’s latest crime?
The 21 and 271 buses are going to be combined into a new route between Lewisham and Highgate, which will go nowhere near the Balls Pond Road.
So we’ll just have the one bus route to the City of London.
On past form, if TfL say they will increase the frequency, I wouldn’t believe them.
I think that TfL have ignored some problems.
The Elderly And Disabled
Between Newington Green and Englefield Road, a higher proportion of the passengers getting on the 21 and 141 buses seem to be in these groups.
- As it’s a nice place to live, I suspect many elderly people have just stayed on.
- I believe that North of the Balls Pond Road, there are some care homes and sheltered housing.
Have TfL analysed their passengers?
Not Everybody Has Cars
There are several blocks of social housing on the Newington Green and Englefield Road stretch and you see a lot of passengers who don’t look like car owners.
The lack of parking and the Low Traffic Neighbourhoods don’t help.
Access To Waterloo
My quickest way to Waterloo, which is London’s busiest rail terminal, is to take a bus to Bank and then get the Drain.
A halved service to Bank station will probably force me to take longer routes.
Tradition
When I was a child in the 1950s, the 141 was the 641 trolley bus, which ran between Winchmore Hill and Moorgate.
People, who live in Wood Green, Turnpike Lane and Manor House still commute to the City by bus, as people have done for over a hundred years.
I suspect a lot of commuters change from the Piccadilly Line to the 141 bus at Manor House station. I certainly use that route if I’m going to Southgate or Cockfosters.
The 21 bus starts at Newington Green, which means if you want to go from Balls Pond Road to Bank, you’ll usually get on a 21 bus, as the 141 buses are full with passengers from further North.
So it looks like to get to Moorgate, we’ll need to get a bus to Angel and then get the Northern Line, after the rerouting of the 21 bus.
Crossrail
This will have a big effect.
Suppose you live in Wood Green and want to get to Crossrail.
There is no obvious connection, but tradition will mean your preferred route will be to take a 141 bus between Manor House and Moorgate.
There will also be a quick route between Moorgate and Liverpool Street station, that I wrote about in London’s First Underground Roller Coaster.
Conclusion
We will need the 21 bus to provide us with a route to Crossrail, as the 141 buses will be full.
The 21 bus is needed where it is and mustn’t be stolen.
Lumo: Why The Latest Edinburgh-London Train Service Could Wean Us Off Planes And Roads
The title of this post, is the same as that of this article on The Conversation.
It is an interesting read and it appears that Lumo’s message is getting through.
With Southwest Airlines Deal, Velocys Presells 100% Of The Output From Its US Biobased Jet Fuel Project
The title of this post, is the same as that of this article on the American Chemical Society.
This is the first paragraph.
The biofuel maker Velocys has signed jet fuel purchase agreements with Southwest Airlines and International Airlines Group. Velocys says it now has agreements for the entire output of the facility it plans to open in Mississippi in 2026. The plant, known as Bayou Fuels, will use gasification and Fischer-Tropsch chemistry to make the fuel from wood waste. It will be fitted with carbon-capture equipment from Oxy Low Carbon Ventures, making its fuel net-negative in CO2 emissions. The two airlines have also agreed to buy the resulting greenhouse gas.
Note that the technology is net-negative in carbon dioxide emissions.
This must be a short-term route to decarbonise existing aviation.
Would A Lumo-Style Service Work Between King’s Cross And Norfolk?
This is a bit of a fantasy and you’ll never know the real reason why I have written it!
With the upgrade of the East Coast Main Line to full digital signalling, there will be a problem South of Hitchin with 140 mph Azumas and Hitachi Class 802 trains and similar from Grand Central , Hull Trains and Lumo hogging the fast lines to and from King’s Cross. I first wrote about it in Call For ETCS On King’s Lynn Route.
One solution would be to replace the current Class 387 trains with a 140 mph train , such as a Hitachi Class 802 variant. This would enable these fast King’s Lynn and Cambridge trains to join the 140 mph trains on a fast run to and from King’s Cross.
The Future Of Cambridge
Cambridge is one of the UK’s four world cities, with its heritage and lately its high position in any technology league table.
The Current Rail Service Between London And Cambridge
Currently, it has a good service into King’s Cross, Liverpool Street and St. Pancras.
- Great Northern – two tph to King’s Cross – A stopping train using Class 700 or Class 387 trains.
- Great Northern – one tph between Ely and King’s Cross – A fast train using Class 387 trains.
- Great Northern – one tph between King’s Lynn and King’s Cross – A fast train using Class 387 trains.
- Thameslink – two tph to Brighton – A semi-fast train using Class 700 trains.
- Greater Anglia – two tph to Liverpool Street – A semi-fast train using Class 720 or Class 379 trains.
Note.
- tph means trains per hour.
- The similar Class 387 and Class 379 trains are both late-model Bombardier Electrostars with sensible seats and a large number of tables. Both train types can or could be modified to run at 110 mph.
- The Class 700 trains are unsuitable for the route, as they have ironing-board seats and no tables. These are only 100 mph trains.
- The Queen’s bottom doesn’t like the Class 700 trains.
A large proportion of the passengers and commuters between to and from Cambridge work in high-tech or information-rich businesses and I believe if the trains were more geared to this market they would attract passengers away from the roads.
The Cambridge Employment Problem
Fast-growing Cambridge is taking over the region and it is always looking for towns and villages to develop as places for dormitories and to build premises for the hundreds of high-tech businesses.
This is one of the reasons why Greater Anglia acquired new Stadler Class 755 trains to run services from Cambridge to Bury St. Edmunds, Ipswich, Norwich, Peterborough and Stansted Airport.
If you’re going to lure Cambridge’s well-paid high-tech commuters out of their cars, you must give them an equivalent seat to their car. The Class 379, 387 and 755 trains do this.
Living In Norfolk And Suffolk And Working In Cambridge
This has always been the choice of many who work in Cambridge, but using rail into Cambridge didn’t really take-off seriously until modern three-car Class 170 trains replaced the single-car Class 153 trains.
Greater Anglia have followed the upward trend in passenger numbers, by running hourly four-car Class 755 trains from Cambridge to both Ipswich and Norwich.
Before the pandemic, it was starting to look like Norwich and Cambridge would soon need a second service, especially with the planned opening of the new Cambridge South station in 2025.
Addenbrooke’s Hospital And The Cambridge Biomedical Campus
Cambridge South station is being built to serve Addenbrooke’s Hospital and Cambridge Biomedical Campus, which intend to be create the foremost medical research cluster in the world.
Staycations And Holiday Homes In East Anglia
Life is changing because of the covids and more people are taking staycations or buying holiday homes.
And many are following the example of the Queen and going to Norfolk for their relaxation.
The Undoubted Need To Improve Rail Services Between London King’s Cross And Norfolk Via Cambridge
These factors convince me that there is a need for a new or repurposed rail service between London King’s Cross and Norfolk via Cambridge.
- The need to provide a high-class commuter service between London and Cambridge.
- The need to bring workers into Cambridge from Norfolk.
- The need to provide a fast high-class rail link to Cambridge South station with all its medical research.
- The need to provide a comprehensive working environment on the trains.
- The need to cater for all those people relaxing in Norfolk after a hard week in London.
It is my view, that a radical design of train is needed for this route.
- It would need to have a high-class interior.
- It would need at least a 125 mph capability, so that it can use the fast lines between Hitchin and King’s Cross.
- The train may need the ability to split and join.
- It would need an independent power capability for running on the Breckland Line between Ely and Norwich.
- Because of Cambridge and because East Anglia is easy country for cycling, it would need a sensible capacity for cycles.
I also believe that because of the need to decarbonise, the train should be zero-carbon.
These are my thoughts.
Operating Speed
Because of running on the fast lines between Hitchin and King’s Cross with the 140 mph trains from the North, I suspect that an operating speed of at least 125 mph is needed. But if the Hitachi trains of LNER, Hull Trains, Lumo and in the future possibly other operators like Grand Central, will be capable of 140 mph, this speed could be desirable.
Speed limits once the trains have left the East Coast Main Line at Hitchin North junction are as follows.
- Hitchin and Cambridge – 90 mph
- Cambridge and King’s Lynn – 90 mph
- Ely and Norwich – 75-90 mph
I can see Network Rail using their expertise to raise the speed limit on sections of these lines.
Flighting Of Trains On The East Coast Main Line
To increase capacity on the East Coast Main Line, I believe that at some point in the not too distant future that trains will be flighted. This will involve two or more trains leaving King’s Cross in a sequence and proceeding with all trains at a safe distance from each other.
I can envisage a flight like this from King’s Cross.
- An Edinburgh train with York as the first stop – Leaves at XX.00
- A Leeds train with Doncaster as the first stop – Leaves at XX.03
- A Lincoln train with Peterborough as the first stop – Leaves at XX.06
- A Cambridge train with Stevenage as the first stop – Leaves at XX.09
Note.
- The Edinburgh train would set the speed.
- Trains would maintain their time behind the lead train.
- Everything could be controlled by the digital signalling.
- Gaps between the trains would be sufficient for a safe stop.
- No train in the flight would make a station stop unless it was the last train in the flight.
- The last train in the flight would drop off and go to their destination.
As there are at least two tph to Edinburgh, Leeds and Cambridge, there would be two main flights per hour leaving King’s Cross, with the second flight perhaps incorporating a service to Hull.
Digital signalling and precise driving would enable the flights to be built in the opposite direction into King’s Cross.
The big advantage would be that instead of needing eight paths per hour on the East Coast Main Line, only two would be needed.
All trains would need to have similar performance, so this is another reason why the Cambridge trains need to be at least 125 mph trains.
Train Interiors
Lumo has broken new ground in train interiors.
- It is one class.
- Everybody gets a decent seat.
- Everybody gets good legroom.
- Everybody gets some form of table.
- There are decent-sized overhead racks for hand-baggage and coats.
- There is space for bicycles and heavy luggage appropriate to the route.
This can be built on to provide a good working and playing environment suited to the passengers who would use a fast King’s Cross and Norfolk service via Cambridge.
- Lots of tables for four, as in the high-class Electrostars.
- Better bicycle storage.
- Better alignment of seats with windows.
Hitachi could obviously produce a train to this specification.
But what about other manufacturers.
Stadler’s Class 755 trains are surely a possibility.
- A senior driver from Greater Anglia told me that the design speed for a Class 755 train is 200 kph or 125 mph.
- They have good seats.
- They have flat floors.
- They have large windows.
- They have step-free access between train and platform.
- Like the Hitachi trains, they are in service.
I believe the closely-related Class 745 trains are probably the best commuter trains in the UK and are the only alternative to the Hitachi trains on a125 mph fully-electrified route.
Bridging The Electrification Gap Between Ely And Norwich
Between Norwich and Ely stations is 53.8 miles and this section is not electrified, although both stations have full electrification.
The line is not heavily used with typically only two passenger trains and the occasional freight trains in each direction in an hour.
This Hitachi infographic describes the Hitachi Regional Battery Train.
A 90 km. range could be sufficient to cover the gap between Norwich and Ely.
Could Hitachi build a Class 802 train or similar with a battery range of 90 km or 56 miles?
Certainly, a speed of 100 mph would probably be sufficient to bridge the gap in a decent time.
Improving The Breckland Line
The Breckland Line is the route between Cambridge and Norwich.
- Cambridge and Norwich is 68.5 miles
- Only the sixteen miles between Cambridge and Ely North junction is electrified.
- There are thirteen stops between the two cities.
- A typical time is 79 minutes
- This is an average speed of just 52 mph.
- The operating speed is 75-90 mph.
I am sure that Network Rail can squeeze a few minutes here and there to get the operating speed up to the 100 mph of the Great Eastern Main Line.
But the big problem at Norwich is the Trowse swing bridge.
It is only single track and it is likely that this bridge will be replaced soon.
This Google Map shows Trowse junction, a short distance South of the swing bridge.
Note.
- The electrified double-track of the Great Eastern Main Line goes across the map from North East to South West.
- The double-track railway to the East of the main line is the unelectrified Breckland Line to Cambridge, which turns West and goes under the main line.
- On the West of the main lines are the Victoria sidings that I wrote about in Greater Anglia Completes Directly-Managed Norwich Victoria Sidings Project.
As the replacement of the swing bridge will require some work to be done to the electrification, I wonder if at the same time Network Rail would electrify the Norwich end of the Breckland Line.
There must be a balance point adding electrification or batteries to the trains.
As the Breckland Line has few freight trains, electrification is not needed for freight.
Ticketing
A high-speed high-capacity service as I’m proposing must be easy to use.
It is a classic route, where nothing short of London-style contactless ticketing will do, as I’m certain this encourages people to use the trains.
As East Anglia is self-contained and has few services that don’t terminate in the area or in London, I am certain that this could be achieved.
If you remove First Class as Greater Anglia has done on many services, you actually simplify the ticketing, so a Lumo-style mid-class is ideal.
High Speed Train Services
Currently Great Northern run two tph from King’s Cross to Ely via Cambridge.
- One service is extended to King’s Lynn.
- I could see the second service extended to Norwich.
Both services would need to be run by 125 mph trains because of the speed of other trains on the East Coast Main Line.
Conclusion
I think duch a system would be possible.
