Was Baldrick An Essex Man?
I have been looking at Network Rail’s page for Beaulieu Park station.
This is the heading.
Network Rail and Essex County Council are working together to develop proposals for the first railway station to be built on the Great Eastern main line for over 100 years.
These two paragraphs outline the project and where the finance is being obtained.
The new station is part of a wider regeneration of the Beaulieu Park estate in Chelmsford with new road infrastructure and up to 14,000 homes.
Essex County Council, in partnership with Chelmsford City Council, successfully secured £218m of funding from the Government’s Housing and Infrastructure (HIF) fund together with £34m contributions from the South East Local Enterprise Partnership and the developers of Beaulieu, Countryside and L&Q.
These features of Beaulieu Park station are listed on the page.
- Three platforms with a central loop line and new tracks to enable stopping services to call at the station while allowing fast trains to pass through unimpeded
- Step free access to all platforms via 2 lifts
- Accessible toilets, baby change facilities, waiting area and space for retail/catering
- Ticketing facilities, with ticket vending machines and a gate line
- Pedestrian and cycle access routes to the station
- 500 spaces for cycle parking and storage
- A bus interchange including bus stands for local services
- Pick up and drop off area with dedicated taxi bays
- Parking for over 700 cars, 5% of which to be designated Blue Badge bays, and motorcycle spaces, as well as dedicated parking for station staff, emergency services, and a dedicated space for service access.
Note.
- How many other parkway stations, other than Ebbsfleet International station have 700 parking spaces?
- The parking at Whittlesford Parkway can only hold 377 vehicles.
- How many other parkway stations have an overtaking loop for faster trains?
Beaulieu Park is not your average parkway station!
I have a few thoughts.
Which Of The Current Services Will Call?
The Network Rail page says this about services.
It will provide additional access to the railway with regular connections to the capital (only 40 minutes from London Liverpool Street station) and other destinations in the east of England. New tracks will enable stopping services to call at the station while allowing fast trains to pass through unimpeded.
Note.
- Trains between London and Hatfield Peverel station typically take under forty minutes.
- Two fast trains per hour (tph) between Liverpool Street and Norwich via Colchester, Ipswich and Stowmarket pass through.
- Only one of the fast trains stops at Chelmsford.
- Four stopping tph, one to each of Braintree, Clacton-on-Sea, Colchester Town and Ipswich pass through.
If all the stopping trains stopped, Beaulieu Park would have the following services.
- Braintree – 1 tph
- Chelmsford – 4 tph
- Clacton-on-Sea – 1 tph
- Colchester – 3 tph
- Colchester Town – 1 tph
- Hatfield Peverel – 1 tph
- Ingatestone – 2 tph
- Ipswich – 1 tph
- Kelvedon – 2 tph
- London Liverpool Street – 4 tph
- Marks Tey – 2 tph
- Romford – 1 tph
- Shenfield – 3 tph
- Stratford – 4 tph
- Witham – 4 tph
All trains are new Class 720 electric trains.
I also feel, that Network Rail could be being cunning.
Suppose, the Liverpool Street and Norwich express, that doesn’t stop at Chelmsford, stopped instead at Beaulieu Park.
- This would give an hourly express service between Beaulieu Park and Norwich, which stopped at Colchester, Manningtree, Ipswich, Stowmarket and Diss.
- It would also enable two tph between Beaulieu Park and Ipswich.
The 700 parking spaces at Beaulieu Park now start to make sense.
- Both Ipswich and Norwich stations are within walking distance of the town centres and the football grounds.
- Ipswich station has a shuttle bus service to the town centre and the hospital.
- Both stations have several local train services.
Beaulieu Park station appears to have been designed as a Park-and-Ride station for the Great Eastern Main Line and all its branches.
Services To And From Lowestoft
In Making Sense Of The New East Anglia Franchise, I looked in detail at Greater Anglia’s promises.
In a section, which is entitled London – Lowestoft – Yarmouth Services, I said this.
There are going to be four direct services between London and Lowestoft each day. This probably initially means two trains to London in the morning peak and two trains back in the evening one.
When, I first moved back to Suffolk in the 1970s, I regularly caught a diesel-hauled train from Wickham Market to London for the day.
This is all motherhood and apple pie for those in Lowestoft wanting to go to London, but I suspect it isn’t the easiest service for a train operator to schedule efficiently and make money.
Would a train operator really want to start a full train at Lowestoft at say six in the morning and then have it wait around all day in London before returning in the evening?
The service hasn’t started.
Services To And From Cambridge Or Peterborough
At some time in the last decade, one of the predecessors of Greater Anglia, used to run a service to Peterborough via Colchester and Ipswich, so that travellers in Essex could catch trains to the North.
Given too that Cambridge has an employment problem, if a service was run, it might attract passengers.
The Class 755 trains Could Serve Bury St. Edmunds, Cambridge, Lowestoft, Newmarket, Peterborough And Yarmouth
Consider.
- A pair of Class 755 trains would leave Liverpool Street.
- They would use electric power to run to Ipswich.
- The trains would run in one of the paths of the current hourly Ipswich service.
- Like their all electric siblings; the Class 745 trains, they would probably run most of the journey at near 100 mph.
- At Ipswich the trains would split.
- One train would go to on to Lowestoft and Yarmouth and the other would go to Cambridge and Peterborough.
If passenger numbers felt it was a good idea, I’m certain, it could be timetabled.
The Chelmsford Avoiding Line
In Will The Chelmsford Avoiding Line Be Rebuilt?, I described the avoiding line, that used to be between the two tracks at Chelmsford station.
It probably saved a few minutes, by allowing fast expresses to pass stopping trains.
Effectively, a new avoiding line is being built at Beaulieu Park, a few miles from the original position at Chelmsford.
So will the fast expresses save a few minutes?
Could The Elizabeth Line Run To Beaulieu Park?
Consider
- The end sections of the Elizabeth Line seem to be busy, as I wrote in Very Busy Lizzie.
- The City of Chelmsford is between Shenfield and Beaulieu Park.
- Paddington and Reading is 35.9 miles.
- Liverpool Street and Hatfield Peverel is 35.9 miles.
So Beaulieu Park is actually closer to London than Reading.
Perhaps, at some time in a few years, passenger traffic between Beaulieu Park and Shenfield will be such, that the Elizabeth Line will be extended to Beaulieu Park.
The ideal service from Beaulieu Park would surely be two tph to Heathrow, as getting to Heathrow from East Anglia by train needs a change at Liverpool Street.
The only drawback is that to work effectively on the Great Eastern Main Line, a sub-variant of the Class 345 trains will be needed with a 100 mph operating speed. I wrote about these trains in Extending The Elizabeth Line – High Speed Trains On The Elizabeth Line.
But they may have the advantage of being able to take the fast lines between Shenfield and Stratford.
Conclusion
Beaulieu Park may just look like any other station to serve a housing development.
But it’s a lot more than that!
- It’s a Park-and-Ride for the whole Great Eastern Main Line and London.
- It should speed up expresses between London and Colchester, Ipswich or Norwich.
- It should improve local connectivity.
- It could take a lot of traffic off the nearby A12.
- It could give the City of Chelmsford its own local metro.
- It could give Heathrow a direct link to much of Essex.
- How much carbon will be saved by passengers?
We need many more well thought out Park-and-Ride stations.
Extending The Elizabeth Line – An Extension To Southend Airport
The Wikipedia entry for Crossrail, has a section for an extension to Southend Airport, where this is said.
Stobart Aviation, the company that operates Southend Airport in Essex, has proposed that Crossrail should be extended beyond Shenfield along the Shenfield–Southend line to serve Southend Airport and Southend Victoria. The company has suggested that a direct Heathrow-Southend link could alleviate capacity problems at Heathrow. The extension proposal has been supported by Southend-on-Sea City Council.
I have written about extending Crossrail to Southend before in Council Launches Campaign To Extend Crossrail To Southend-on-Sea.
In that post, I gave these reasons.
- Extra capacity between London and Southend
- A more intensive service to Southend Airport
- A twenty-four hour service to Southend Airport
- Enabling housing
- Taking pressure from Liverpool Street
I came to the conclusion, that extending the Elizabeth Line to Southend could have a lot going for it.
Times Change
But that post was written nearly four years ago and times change and they will change more in the next few years.
The Elizabeth Line Trains Are Shorter Than The Liverpool Street And Southend Victoria Trains
This has also happened and the pair of five-car Class 720 trains, that Greater Anglia use for Southend Victoria services are over thirty metres longer than the Elizabeth Line’s nine-car Class 345 trains.
This would mean that there would be no need for platform lengthening along the route to Southend Victoria.
Zero-Carbon Aircraft Are Under Development
Zero-carbon aircraft like the Heart Aerospace ES-19 could be in service by 2027. These aircraft will probably have a limited range of around 400 km and a charge time of 40 minutes.
- Southend Airport’s position on the East side of London would enable the creation of zero-carbon flights to places like Amsterdam, Brussels, Lille, Paris and Rotterdam.
- A quick estimate indicates that aircraft like the ES-19 could fly from Southend to Amsterdam and recharge in around two hours.
- Intensively scheduled, these electric aircraft could make several round trips per day.
- Would almost silent electric aircraft be able to fly twenty-four hours per day?
These flights could seriously increase the number of passengers to Southend Airport before the end of the decade.
More Housing
I think more housing will be built between Shenfield and Southend, which will increase the need for more services past Shenfield.
The Great Eastern Main Line Will Have Full Digital Signalling
More and more trains will be running on the Great Eastern Main Line and like other main lines in the UK, it will receive full digital signalling, which would probably be applied to the Shenfield and Southend Line.
This would give the extra capacity to Southend Victoria, that running the Elizabeth Line to Southend Airport and Southend Victoria would need.
Possible Services
I think there are two main possible options, but there may be others.
- A long Elizabeth Line extension all the way to Southend Victoria.
- A short Elizabeth Line extension only as far as Southend Airport.
My feelings are as follows.
- The Greater Anglia service should remain as it is with three trains per hour (tph) calling at all stations to Shenfield, Stratford and Liverpool Street.
- Perhaps three or four Elizabeth Line tph would extend to Southend Victoria, calling at all stations.
- All Elizabeth Line trains would call at all stations to and from London, as they do now!
Full digital signalling would handle the extra trains.
Conclusion
I think it will be unlikely that the Elizabeth Line will be extended to Southend in the next few years, but before the end of the decade, I can certainly see limited Elizabeth Line services going all the way to Southend Victoria.
Diss Station – 19th May 2022
I went to Diss station for the first time today on a train, although I have caught a train from the station a couple of times.
These are my thoughts.
Long Platforms
Consider.
- The platforms are long enough to take two full-length twelve-car Class 745 trains, which are nearly 240 metres long.
- I suspect the platforms can also accept a pair of five-car Class 720 trains, which would be 244 metres long.
If this is true at all Inter-City stations, this must mean that Greater Anglia can still run a full service, if they are short of Class 745 trains.
Car Parking
This Google Map shows the extensive car parking at Diss station.
Note.
- There are two tracks and two platforms, with the London-bound platform on the Eastern side.
- There is parking on both sides of the tracks.
- According to the National Rail web site, there appears to be 316 parking bays on the London-bound side.
- A sign in the tenth picture shows a £2.50 All-Day parking deal on the Norwich-bound platform.
- The Internet shows a lot of competitively-priced parking around the station.
Commuters to London, Ipswich or Norwich will have to cross the line in the morning or evening and there are no lifts to make that easy.
A Step-Free Bridge At Diss
Network Rail had a competition a few years ago in conjunction with RIBA to design a stylish, affordable and easy-to-install footbridge and this was the winner.
This design is also under development.
I think one of these bridges could possibly be installed at Diss station at the Northern end of the station.
- Both bridges would appear to have small footprints.
- They are designed to clear 25 KVAC overhead electrification.
- Both bridges appear to be able to be built to a flexible width. I suspect this might allow one end of the bridge could be in a car park and the other on the opposite platform.
- Both are fully step-free.
- The composite bridge might be better because of a lower weight.
- The first bridge appears to be enclosed, so would work better in Manchester.
- I suspect that both could be installed after creating an appropriately-sized concrete base on either side of the tracks, by lifting in the bridge by means of a rail-mounted crane.
It is now over three years since the first design won the Network Rail/RIBA competition. That is just too long to get a prototype bridge built and installed.
Toilets
The toilets at the station were of an excellent standard. But this is getting increasingly common these days.
The Future Of The Class 387 And Class 379 Trains
This post is to try to get some logic into everybody’s comments on UK’s First 100mph Battery-Diesel Hybrid Train Enters Passenger Service, which are about the Class 379 trains.
Here are my thoughts about the current situation.
Class 379 Trains
I regularly use Hackney Downs and Liverpool Street stations.
A few months ago, you would see Class 379 trains on services to Cambridge and Hertford North.
At the present time, you rarely see them, as these services now seem to be run by new Class 720 trains, with the Stansted services being run by Class 745 trains.
There are also articles like this one on Rail Technology Magazine, which is entitled Greater Anglia’s New Rolling Stock Helps To Drive Record Autumn Results.
These are the first three paragraphs.
Greater Anglia’s new rolling stock has helped drive the operators record-beating autumn performance results over the challenging autumn months.
During autumn 2021 Greater Anglia recorded an overall punctuality score of 94.48% from 19th September 2021 – 8th January 2022.
This was the best autumn performance ever recorded by the train company.
It would appear that Greater Anglia are pleased with their new stock, which surely means that the thirty Class 379 trains can be moved on, stored or converted to battery-electric operation.
c2c’s Class 387 Trains
c2c has six Class 387 trains, which are similar to the Class 379 trains.
Currently, because of cracks in Class 800 trains, three of them are on loan to GWR.
But in the next year or so, these six trains will be moved on or stored as c2c have ordered twelve Class 720 trains to replace the Class 387 trains.
Southern’s Class 387 Trains
Southern has twenty-seven Class 387 trains for the Gatwick Express, of which three are used by Great Northern, who are a sister company of Southern, and six are on loan to GWR
Great Northern’s Class 387 Trains
Great Northern has twenty-nine Class 387 trains of its own and three on loan from Southern.
These trains are used mainly on Cambridge, Ely and Kings Lynn services out of King’s Cross.
Great Western Railway (GWR)’s Class 387 Trains
Great Western Railway has forty-five Class 387 trains of its own, three on loan from c2c and six on loan from Southern.
The Battery-Electric Class 379 Train
I rode this prototype train in 2015.
An Outwardly Normal Class 379 Train
I think it is reasonable to assume, that as battery technology has improved in the seven years since I rode this train, that converting Class 379 trains to battery-electric operation would not be a challenging project.
Creating A Battery-Electric Class 387 Train
If the Class 387 train is as internally similar to the Class 379 train as it outwardly looks, I couldn’t believe that converting them to battery-electric operation would be that difficult.
Conclusion
I feel the way to proceed is to create a small fleet of both battery-electric Class 379 and Class 387 trains and assess their performance, reliability and customer acceptance.
Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet
The title of this post, is the same as that of this press release from Alstom.
This is the first two paragraphs.
Alstom, Britain’s leading train manufacturer and maintenance provider, and Eversholt Rail, leading British train owner and financier, have today announced a Memorandum of Understanding aimed at delivering the UK’s first ever brand-new hydrogen train fleet.
The two companies have agreed to work together, sharing technical and commercial information necessary for Alstom to design, build, commission and support a fleet of ten three-car hydrogen multiple units (HMUs). These will be built by Alstom in Britain. The new HMU fleet will be based on the latest evolution of the Alstom Aventra platform and the intention is that final contracts for the fleet will be signed in early 2022.
This is an Alstom visualisation of the train.
The first thing I notice is that the train doesn’t have the same aerodynamic nose as this current Class 710 train, which is one of the London Overground’s Aventras.
Note how the lights, coupler position and the front-end structure are all different.
These are my further thoughts on the design.
The Aventra’s Traction System
In this article in Global Rail News from 2011, which is entitled Bombardier’s AVENTRA – A new era in train performance, gives some details of the Aventra’s electrical systems. This is said.
AVENTRA can run on both 25kV AC and 750V DC power – the high-efficiency transformers being another area where a heavier component was chosen because, in the long term, it’s cheaper to run. Pairs of cars will run off a common power bus with a converter on one car powering both. The other car can be fitted with power storage devices such as super-capacitors or Lithium-ion batteries if required. The intention is that every car will be powered although trailer cars will be available.
Unlike today’s commuter trains, AVENTRA will also shut down fully at night. It will be ‘woken up’ by remote control before the driver arrives for the first shift
This was published over ten years ago, so I suspect Bombardier (or now Alstom) have refined the concept.
Bombardier have not announced that any of their trains have energy storage, but I have my suspicions, that both the Class 345 and Class 710 Aventra trains use super-capacitors or lithium-ion batteries, as part of their traction system design.
- I was told by a Bombardier driver-trainer that the Class 345 trains have an emergency power supply. When I said “Batteries?”, He gave a knowing smile.
- From the feel of riding on Class 710 trains, as a Control Engineer, I suspect there is a battery or supercapacitor in the drive system to give a smoother ride.
I also feel that the Aventra has been designed, so that it can accept power from a large variety of sources, which charge the battery, that ultimately drives the train.
The Formation Of A Three-Car Aventra
The only three-car Aventra is the Class 730/0 train.
I have not seen one of one of these trains in the metal and the formation can’t be found on the Internet. But Wikipedia does show the pantograph on the middle car.
In The Formation Of A Class 710 Train, I said this.
Here is the formation of the train.
DMS+PMS(W)+MS1+DMS
The plates on the individual cars are as follows.
DMS – Driving Motored Standard
-
- Weight – 43.5 tonnes
- Length – 21.45 metres
- Width 2.78 metres
- Seats – 43
The two DMS cars would appear to be identical.
PMS 
-Pantograph Motored Standard
-
- Weight – 38.5 tonnes
- Length – 19.99 metres
- Width 2.78 metres
- Seats – 51
The signifies a wheelchair space.
MS1 – Motored Standard
-
- Weight – 32.3 tonnes
- Length – 19.99 metres
- Width 2.78 metres
- Seats – 52
It is similar in size to the PMS car, but has an extra seat.
So could the formation of a three-car Aventra be?
DMS+PMS(W)+DMS
I have just removed the MS1 car.
This would mean that a three-car Aventra has the following dimensions and capacity.
- Weight – 125.5 tonnes
- Length – 62.89 metres
- Seats – 137
There will probably be a difference between these figures and those of a three-car Class 730 train, as those trains have end-gangways.
Could All The Hydrogen Gubbins Fit Underneath The Train?
These pictures show the space underneath a Class 710 train.
If you also look at Alstom’s visualisation of their Hydrogen Aventra on this post, there would appear to be lots of space under the train.
It should also be noted that Birmingham University’s engineers have managed to put all of the hydrogen gubbins underneath the floor of Porterbrook’s Class 799 train.
Looking at my pictures, you can see the following.
- The two DMS (Driving Motored Standard) cars have large boxes underneath
- The MS1(Motored Standard) car is fairly clear underneath. But this will probably not be there in a three-car train.
- The PMS (Pantograph Motored Standard) car has some space underneath.
If more space needs to be created, I suspect that the cars can be lengthened, between the bogies. The Class 710 trains have twenty metre intermediate cars, whereas some versions have twenty-four metre cars.
I believe that Aventras have been designed, so that various power sources could be installed under the floor.
When the Aventra was designed, over ten years ago, these could have included.
- A diesel generator and all the fuel tanks and cooling systems.
- A battery or other energy storage system.
Since then two other suitable power sources have been developed.
- Rolls-Royce, Honeywell and others have developed small and powerful gas-turbine generators.
- Ballard Power Systems and others have developed hydrogen fuel cell generators.
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.
Does The Alstom Hydrogen Aventra Have Longer Cars?
I have been looking at pictures of Aventras on Wikipedia and in my own archive.
It appears that only Aventras with twenty-four metre carriages have five windows between the pair of double-doors in the intermediate carriages.
This picture shows the PMS car from a Class 710 train.
The PMS car is to the right and has four windows between the doors.
This is the side view of one of Greater Anglia’s Class 720 trains.
It has twenty-four metre intermediate cars and five windows.
It looks to me that the Alstom Hydrogen Aventra will have twenty-four metre cars.
This will give an extra four x 2.78 metres space under the train compared to a Class 710 train.
It would also appear that the Aventras with twenty-four metre cars also have an extra window in the driving cars, between the doors.
Does the four metre stretch make it possible to position tubular hydrogen tanks across the train to store a practical amount of hydrogen?
Is The Alstom Hydrogen Train Based On A Three-Car Class 730/0 Train?
I have just found this video of a three-car Class 730/0 under test.
And guess what! It has five windows between the doors.
But then it is a train with twenty-four metre cars.
It looks to me, that Alstom have looked at the current Aventra range and decided that the three-car Class 730/0 could be the one to convert into a useful train powered by hydrogen.
So if it is a Class 730/0 train with hydrogen gubbins under the floor, what other characteristics would carry over.
- I suspect Aventras are agnostic about power and so long as they get the right quantity of volts, amps and watts, the train will roll along happily.
- But it means that the train can probably use 25 KVAC overhead electrification, 750 VDC third-rail electrification, hydrogen or battery power.
- I wouldn’t be surprised if if could use 15 KVAC and 3KVDC overhead electrification for operation in other countries, with perhaps a change of power electronics or transformer.
- The interior layout of the trains can probably be the same as that of the Class 730/0 trains.
- The Class 730/0 trains have an operating speed of 90 mph and this could be good enough for hydrogen.
This could be a very capable train, that could find a lot of applications.
Could The Proposed Alstom Hydrogen Aventra Be Considered To Be A Class 730/0 Train With A Hydrogen Extender?
It appears that the only difference between the two trains is that the proposed Alstom Hydrogen Aventra has a hydrogen propulsion system, that can be used when the electrification runs out.
The hydrogen fuel cell will convert hydrogen into electricity, which will either be used immediately or stored in a battery on the train.
The Class 730/0 trains have already been ordered to run services on Birmingham’s electrified Cross-City Line.
There are plans to expand the line in the future and I do wonder if the proposed Alstom Hydrogen Aventras could be the ideal trains for extending the network.
How Does The Alstom Hydrogen Aventra Compare With The Class 600 Breeze Train?
The Class 600 train, which is based on the British Rail-era Class 321 train seems to have gone cold.
If it was a boxing match, it would have been stopped after the fourth round, if not before.
This Alstom visualisation shows the Class 600 train, which is also known as the Breeze.
I have a feeling that Alstom have done their marketing and everybody has said that the Class 600 train wouldn’t stand up to a modern train.
- When you consider that each end of the train is a hydrogen tank, I wonder if possible passenger and driver reaction has not been overwhelmingly positive.
- The project was announced in January 2021 and in the intervening time, hydrogen technology has improved at a fast pace.
- There could even be a battery-electric version of the proposed Alstom Hydrogen Aventra.
- The modern train could possibly be lengthened to a four or five car train.
It does strike me, that if Alstom are going to succeed with hydrogen trains, that to carry on with the Class 600 train without an order into the future is not a good idea.
How Does The Alstom Hydrogen Aventra Compare With The Alstom Coradia iLint?
The Alstom Coradia iLint is the world’s first hydrogen train.
It is successfully in service in Germany.
These are some characteristics of the Coradia iLint from the Internet.
- Seats – 180
- Length – 54.27 metres
- Width – 2.75 metres
- Height – 4.31 metres
- Operating Speed – 87 mph
- Range – 370-500 miles
- Electrification Use – No
The same figures for the Alstom Hydrogen Aventra are as follows.
- Seats – 164
- Length – 72 metres
- Width – 2.78 metres
- Height – 3.76 metres
- Operating Speed – 90 mph
- Range – Unknown
- Electrification Use – Unknown, but I would expect it is possible.
Note.
- I have taken figures for the Alstom Hydrogen Aventra from the Class 730/0 train and other Aventras.
- The number of seats is my best estimate from using the seat density of a Class 710 train in a 24 metre long car.
- The width and height seem to be standard for most Aventras.
- Alstom have said nothing about the range on hydrogen.
- I am surprised that the Aventra is the wider train.
But what surprises me most, is how similar the two specifications are. Had the designer of the original Lint hoped to sell some in the UK?
What Is The Range Of The Alstom Hydrogen Aventra?
When they launched the Breeze, Alstom were talking about a range of a thousand kilometres or just over 620 miles.
I have talked to someone, who manages a large bus fleet and they feel with a hydrogen bus, you need a long range, as you might have to position the bus before it does a full day’s work.
Would similar positioning mean a hydrogen train needs a long range?
I suspect it would in some applications, but if the train could use electrification, as I suspect the Alstom Hydrogen Aventra can, this must help with positioning and reduce the range needed and the amount of hydrogen used.
Would Alstom aim to make the range similar to the Coradia iLint? It’s probably a fair assumption.
Could the Alstom Hydrogen Aventra Be Extended To Four Or Five Cars?
I don’t see why not, as Aventras are designed to be lengthened or shortened, by just adding or removing cars, just like their predecessors the Electrostars were.
I can certainly see routes, where a longer Alstom Hydrogen Aventra could be needed and if Alstom have also decided that such a train could be needed, they will surely have investigated how to lengthen the train.
Applications In The UK
These are links to a few thoughts on applications of the trains in the UK.
- Alstom Hydrogen Aventras And Extension Of The Birmingham Cross-City Line
- Alstom Hydrogen Aventras And The Reopened Northumberland Line
- Alstom Hydrogen Aventras And Great Western Branch Lines Between Paddington And Oxford
- Alstom Hydrogen Aventras And The Uckfield Branch
There are probably a lot more and I will add to this list.
Applications Elsewhere
If the Coradia iLint has problems, they are these.
- It can’t use overhead electrification, where it exists
- It has a noisy mechanical transmission, as it is a converted diesel multiple unit design.
The Alstom Hydrogen Aventra can probably be modified to use electrification of any flavour and I can’t see why the train would be more noisy that say a Class 710 train.
I suspect Alstom will be putting the train forward for partially-electrified networks in countries other than the UK.
Conclusion
This modern hydrogen train from Alstom is what is needed.
It might also gain an initial order for Birmingham’s Cross-City Line, as it is a hydrogen version of the line’s Class 730/0 trains.
But having a hydrogen and an electric version, that are identical except for the hydrogen extender, could mean that the trains would be ideal for a partially-electrified network.
There could even be a compatible battery-electric version.
All trains would be identical to the passenger and probably the driver too. This would mean that mixed fleets could be run by an operator, with hydrogen or battery versions used on lines without electrification as appropriate.
Carbon Emissions Cut With The New Trains In East Anglia
The title of this post, is the same as that of this article on Rail Advent.
The article explains the various ways Greater Anglia’s new trains cut carbon emissions.
The picture shows a PowerPack car of a Class 755 train.
The article indicates that these cars are more intelligent than I thought.
- Regenerative braking can be used to power the trains systems.
- The trains have a coast mode to cut emissions.
- The article also confirms, that with time some diesel engines will be replaced with batteries.
It will be interesting to see how much carbon emissions are saved, when the trains have batteries and software developments are complete.

Essex Councillors Call For Underground Link
The title of this post, is the same as that of this article on Railnews.
This is the first paragraph.
Councillors in Harlow are calling for a new Underground link, saying that they are examining ‘all possibilities for improving and modernising transport connections’.
I’ve tackled this subject before in Does Harlow Need An Improved Train Service?, but this time I’m starting with what is possible and working backwards.
Harlow’s Current Train Service
Currently, these trains serve Harlow Town station.
- Stratford and Bishops Stortford – 2 tph – via Lea Bridge, Tottenham Hale, Waltham Cross, Cheshunt, Broxbourne and Sawbridgeworth
- London Liverpool Street and Cambridge North – 1 tph – via Tottenham Hale, Cheshunt, Broxbourne, Bishop’s Stortford, Audley End, Whittlesford Parkway and Cambridge
- London Liverpool Street and Cambridge North – 1 tph – via Tottenham Hale, Cheshunt, Broxbourne, Roydon, Sawbridgeworth, Bishop’s Stortford, Stansted Mountfitchet, Elsenham, Newport, Audley End, Great Chesterford, Whittlesford Parkway, Shelford and Cambridge
- London Liverpool Street and Stansted Airport – 1 tph – via Tottenham Hale
- London Liverpool Street and Stansted Airport – 1 tph – via Tottenham Hale and Stansted Mountfitchet
In addition these services run through Harlow Town station without stopping.
- London Liverpool Street and Stansted Airport – 2 tph – via Tottenham Hale
Note.
- tph is trains per hour
- The Stansted services are fast services and take 29 minutes between London Liverpool Street and Harlow Town.
- The other services seem to take a few minutes longer.
Summarising the services gives the following.
- Eight tph pass through the station of which six tph stop.
- Cambridge and Cambridge North has a 2 tph service.
- London Liverpool Street has a 4 tph service.
- Stansted Airport has a 2 tph service.
- Stratford has a 2 tph service.
- Tottenham Hale has a 6 tph service.
Each of Greater Anglia’s new Class 720 trains, when working as a ten-car formation can carry well over a thousand passengers.
Harlow Town station has a fairly good service, but it could probably be improved.
What Are Harlow’s Councillors Suggesting
This paragraph in the Railnews article gives the councillors wish list.
Harlow Councillor Michael Hardware is portfolio holder for strategic growth. He said: ‘With Harlow’s close proximity to London our plans include investigating the potential for the extension of the central line to Harlow, lobbying to extend London Transport Zones to Harlow, examining connectivity to Crossrail 2 and promoting four tracking of the main line to Stansted Airport as well as improving existing public transport links in and out of the town.
I’ll look at each proposal in turn.
Extending The Central Line To Harlow
Epping and Harlow are about nine miles apart.
This Google Map shows the two towns and the M11 that runs to the East of both towns.
Note.
- Epping is in the South-West corner of the map.
- Harlow, which is a large town of nearly 90,000 residents is at the top of the map.
- The M11 runs North-South across the map to the East of both towns.
- North Weald Airfield lies to the East of the motorway.
Would it be possible to run an extension of the Central Line from Epping to Harlow?
It could run up the West side of the motorway.
- The terminus could be in South-East Harlow close to Junction 7 of the M11.
- Any plans for the development of North Weald Airfield could have a big effect on any plans.
This Google Map shows the location of Epping station with respect to the motorway.
Note Epping station is in the South-West corner of the map.
Running North-East from the station, the dark green scar of the single-track Epping Ongar Railway can be picked out, as it runs between St. Margaret’s Hospital and the village of Coopersale.
This third Google Map shows the railway as it passes under the M11.
Would it be possible to use the route of this line to connect to a new line alongside the motorway?
This fourth Google Map shows Epping tube station.
Note.
- The station has two platforms, but is not step-free.
- It has a large car-park.
- Trains take thirty-seven minutes between Epping and Liverpool Street stations.
- Trains have a frequency of nine tph.
This map from cartometro.com shows the track layout at Epping station and the interface with the Epping Ongar Railway.
Note.
- The Epping Ongar Railway has always been single track.
- The crossovers to the South of Epping station allow either platform to be used for Central Line services.
- When the Central Line ran to Ongar, it looks like all services used Platform 1 at Epping.
I feel that it might be possible to create an extension to Harlow, by doing something like the following.
- Add a second bi-directional track alongside the Epping Ongar Railway between Epping station and the M11.
- Extend Platform 1 to the North, so that the heritage trains can load and unload passengers at Epping station.
- The Central Line platforms would be unaltered, so could still handle the nine tph they currently handle.
- Trains to and from Harlow would always use Platform 2.
At the M11, the new bi-directional track would turn North and become double-track to Harlow.
- The double-track would allow trains to pass.
- If the rolling stock for the Central Line has been renewed, it might be possible to run the extension on battery power.
- If Harlow had a single platform, it would be possible to run four tph to Harlow.
- The current 2012 Stock trains have a capacity of around a thousand passengers.
- I estimate that trains would take about ten minutes between Epping station and the new Harlow station.
I feel something is possible, but building the line might be easier if new battery-electric trains were available, as this would probably allow the extension to be built without electrification.
On the other hand, it might not have the greatest financial case.
- It could be difficult to add large numbers of passengers to the Central Line.
- At around forty-seven minutes, the Central Line service will be slower than the main line trains, which currently take around a dozen minutes less.
I’ll be interested to see what the professionals say.
Extending London Transport Zones To Harlow
Harlow Town station has ticket barriers, but I don’t think it is part of London’s contactless card zone.
Adding Harlow Town and all stations between Harlow Town and the zone could be very beneficial to passengers and train companies.
Examining Connectivity To Crossrail 2
I think that in the current economic situation this should be discounted.
- It is a very expensive project.
- Building it will cause tremendous disruption on the West Anglia Main Line.
- It is only planned to go as far as Broxbourne station.
But I don’t think politicians from outside London and the South-East would sanction another massive project for London.
I don’t think Crossrail 2 will ever be build in its currently proposed form.
Four Tracking Of The Main Line To Stansted Airport
Consider.
- Currently, the numbers of trains on the West Anglia Main Line is under twelve tph.
- Modern double-track railways with the latest digital in-cab signalling like Thameslink and Crossrail can handle twice this number of trains.
- The West Anglia Main Line will be getting new trains with better acceleration.
Four-tracking is mainly needed to cut times to Cambridge and Stansted Airport, but I suspect that with some clever design and improved signalling, the current double-track can be improved significantly.
Improving Existing Public Transport Links In And Out Of The Town
I think that this could be a fruitful area.
- As I said earlier, Harlow has only 6 tph trains stopping in the station.
- I believe this could be increased to at least 10 tph, if the West Anglia Main Line were to be modernised.
- Extending London Transport Zones To Harlow, which I discussed earlier would surely help.
- Is there enough car parking?
- Are there enough buses to the stations?
- Would a fleet of zero-carbon buses tempt people to use them?
- Would it be possible to run a hydrogen commuter bus service up and down the M11 between say Harlow and Ilford for Crossrail?, as is being done in Dublin, that I wrote about in Three Hydrogen Double Decker Buses Set For Dublin.
Hopefully, Harlow’s councillors would have a few good ideas.
A Few Thoughts On What Is Possible
These are a few of my thoughts on what is possible.
Digital Signalling Could Increase The Number of Trains Per Hour Significantly
Consider.
- Currently, the West Anglia Main Line handles ten tph between Liverpool Street and Bishops Stortford.
- Thameslink handles 24 tph with digital signalling.
- Crossrail will handle 24 tph with digital signalling.
- High Speed Two will handle eighteen tph.
I certainly believe that another four tph could be easily handled through the two Harlow stations, with full digital signalling.
Perhaps a frequency of eight tph, that would match TfL Rail between London Liverpool Street and Shenfield would be ideal.
If it works for Shenfield it should work for Harlow!
Rebuild Cheshunt Station
Cheshunt station with its level crossing is a bottleneck and any increase in the number of trains through the station will need the level crossing to be replaced by a bridge.
But developers are talking of high class housing in the area and removal of the level crossing appears to be in their plans.
New High-Capacity Class 720 Trains
Pairs of five-car Class 720 trains are coming to the West Anglia Main Line and each pair will carry over a thousand passengers.
These will be used on four tph, that call at Harlow Town station.
Turn Trains In The High Meads Loop at Stratford Station
The single-track Wirral Line Loop under Liverpool handles up to sixteen tph.
Network Rail built a double-track loop under the Eastfield Shopping Centre, which calls at Platforms 11 and 12 in Stratford.
If this loop was used to turn trains it could probably handle at least twelve tph on one platform.
Liverpool Street currently handles these trains that go up the West Anglia Main Line or the Lea Valley Lines.
- 6 tph – Greater Anglia
- 6 tph – London Overground
It looks to me that the terminal capacity in London could be as high as 20 tph.
Run More Trains On A Digitally-Signalled Route Through Seven Sisters
Just four tph run on the London Overground route through Seven Sisters station.
Compare that with the East London Line of the London Overground, where sixteen tph run between Dalston Junction and Surrey Quays stations.
The London Overground has ambitions to run four tph to Cheshunt and Enfield Town, as they do to Chingford, but that would only up the frequency through Seven Sisters to eight tph.
The tracks in the area also allow trains from Stratford to use the lines through Seven Sisters stations to go North.
Run West Anglia And Lea Valley Services Together
Currently, Greater Anglia and London Overground seem to do their own things, but surely properly integrated and with the moving of more services to the London Overground, I suspect that everything could be more efficient.
I believe that by using Liverpool Street and Stratford as twin London terminals for Lea Valley services, that upwards of twenty tph can on digitally-signalled West Anglia Main Line and the Lea Valley Lines.
These are the current trains.
- Bishops Stortford – 2 tph
- Cambridge North – 2 tph
- Cheshunt – 2 tph
- Chingford – 4 tph
- Enfield Town – 2 tph
- Hertford East – 2 tph
- Stansted Airport – 4 tph
Note.
- This is a total of eighteen tph
- The pinch point is surely the stretch between Bethnal Green and Clapton stations, which handles 14 tph including a mix of fast expresses and London Overground services.
- On the other hand the route through Seven Sisters is handling just four tph.
- Ten tph run between Tottenham Hale and Cheshunt stations on the West Anglia Main Line.
- Only two tph terminate in Stratford.
If the Cheshunt and Enfield Town services are increased to 4 tph, as is London Overground’s aspirations we get the following.
- Bishops Stortford – 2 tph
- Cambridge North – 2 tph
- Cheshunt – 4 tph
- Chingford – 4 tph
- Enfield Town – 4 tph
- Hertford East – 2 tph
- Stansted Airport – 4 tph
Note.
This is a total of twenty-two tph.
But there is still plenty of spare capacity at Stratford and through Seven Sisters.
If our objective is more trains through Harlow, why not double up the Stratford and Bishops Stortford service.
- Bishops Stortford – 4 tph
- Cambridge North – 2 tph
- Cheshunt – 4 tph
- Chingford – 4 tph
- Enfield Town – 4 tph
- Hertford East – 2 tph
- Stansted Airport – 4 tph
Note.
- This is a total of twenty-four tph.
- Harlow will have eight tph to and from London.
- There will be 8 tph through Seven Sisters.
- There will be twelve tph between Tottenham Hale and Cheshunt stations on the West Anglia Main Line.
- Four tph will terminate at Stratford.
Perhaps to reduce the trains on the West Anglia Main Line, the Hertford East trains could go via Seven Sisters.
But that would mean that stations like Brimsdown and Ponders End would lose a lot of their service.
So why not add extra stops to the Bishops Stortford services?
Conclusion
I believe that by doing the following.
- Adding digital signalling to all lines.
- Turning more trains at Stratford.
- Using the route through Seven Sisters at a much higher frequency.
- Rebuilding Cheshunt station and level crossing.
- Reorganising stops on the West Anglia Main Line.
That it would be possible to create a high-frequency Metro up the Lea Valley.
Except for the digital signalling and Cheshunt station, there is not much work to do on the infrastructure.
Tidying Up At Cheshunt Station – 4th August 2021
As I approached Cheshunt station, it looked like there had been some tidying up on the Western side of the line.
Unfortunately, I didn’t have my camera handy, so I was unable to take any pictures.
But I did take these pictures later from the station.
It does seem that Network Rail are tidying up the inside of the bend.
The Internet offers no clue, as to what is happening, but it could be anything from improving the car park entrance, to installing a second bay platform at the station, so that more trains can be run to and from Liverpool Street.
But there is a clue here in West Anglia Route Improvement – Cheshunt Station – 26th February 2017, which from the date is four years old.
The Google Map in this post, shows the Southern end of Platform 2 to be a different shape, to the pictures I took today.
It looks like the platforms have been lengthened.
- Originally, they could handle an eight-car Class 317 train, which are 160 metres long.
- It looks like now, they can handle a pair of five-car Class 720 trains, which are 244 metres long.
This will allow pairs of five-car Class 720 trains to work Cambridge services.
Pairs of four-car Class 710 trains are only 166 metres long, so they don’t need any platform lengthening.
The Sunset Studios Effect
If I was right in The Location Of Sunset Studios In Broxbourne, that a station will be built on the London Overground between Turkey Street and Theobalds Grove to serve the studio complex, then this may require modifications at Cheshunt, if traffic increases substantially.
- Cheshunt station will need to be step-free.
- Cheshunt station will need better passenger facilities, like more ticket machines.
- Cheshunt station may need more car parking.
- The bay platform at Cheshunt station will need to be handle upwards of four trains per hour (tph), all of which will be pairs of four-car trains.
A large housing development is planned for just to the North of Cheshunt station and hopefully, the developer will sort a lot of these issues.
Class 321 Renatus Trains At Wickford And On The Crouch Valley Line
This article on Rail Advent indicated that the platform extension at Wickford station had been completed, so that five-car Class 720 trains can work the Crouch Valley Line.
This morning I went to look at the progress and took these pictures.
Note.
- Platform 1 has been extended at the London end.
- The two trains working the branch were Class 321 Renatus trains.
- The stations on the branch seemed to have been spruced up.
I suspect Greater Anglia are expecting a lot more commuters and visitors.
- But then the area is getting a lot more housing.
- There are fast direct trains to and from London Liverpool Street on a railway with refurbished electrification.
- Burnham-on-Crouch is one of the foremost yachting towns.
- Remember the area is not far from Snowgoose Country.
- The new Wallasea wetlands that were created with the tunnel spoil from Crossrail’s tunnels is not far away.
This Google map shows Burnham-on-Crouch and Wallasea Wetlands.
Note.
- Burnham-on-Crouch with its station in the North-West corner of the map.
- Wallasea Wetlands are marked by the red arrow.
I don’t think it will be long before an appropriately-powered ferry is provided across the River Crouch.
I also have some thoughts.
The Class 321 Renatus Trains
The Class 321 Renatus trains may be a 2017 conversion of a 1990-built British Rail Class 321 train, but that doesn’t mean they are a cheap and nasty conversion.
So until all the Class 720 trains are in service, they are a more than adequate stand-in.
I was told that the Class 720 trains will be in service on the branch in September.
The Snow Goose
The Snow Goose is one of the great books of the Twentieth Century, written by the American; Paul Gallico.
This summary of the plot is from Wikipedia.
The Snow Goose is a simple, short written parable on the regenerative power of friendship and love, set against a backdrop of the horror of war. It documents the growth of a friendship between Philip Rhayader, an artist living a solitary life in an abandoned lighthouse in the marshlands of Essex because of his disabilities, and a young local girl, Fritha. The snow goose, symbolic of both Rhayader (Gallico) and the world itself, wounded by gunshot and many miles from home, is found by Fritha and, as the human friendship blossoms, the bird is nursed back to flight, and revisits the lighthouse in its migration for several years. As Fritha grows up, Rhayader and his small sailboat eventually are lost in the Dunkirk evacuation, having saved several hundred men. The bird, which was with Rhayader, returns briefly to the grown Fritha on the marshes. She interprets this as Rhayader’s soul taking farewell of her (and realizes she had come to love him). Afterwards, a German pilot destroys Rhayader’s lighthouse and all of his work, except for one portrait Fritha saves after his death: a painting of her as Rhayader first saw her – a child, with the wounded snow goose in her arms.
It is not a book, you’d expect an American to write about the dark days of World War II in the UK.
But as Christopher Nolan showed in his film, Dunkirk was the battle in World War II, that stiffened up the sinews and summoned up the blood.
Wickford Station
The pictures show that Wickford station is being rebuilt.
I would think it needs a speed-free bridge.
Does Harlow Need An Improved Train Service?
I ask this question, because I am increasingly seeing articles like this one on My London, which is entitled The Large Town Just Outside London Desperate For A London Underground Station.
The town is Harlow.
This Google Map shows the West Anglia Main Line, as it runs through the North of the town.
Note.
- Harlow Town station towards the South West of the map.
- Harlow Mill station towards the North East of the map.
- The West Anglia Main Line running between the two stations.
On the face of it the town seems well-served by the trains.
Harlow Town Station
This Google Map shows Harlow Town station to a larger scale.
Note.
- The station has four platforms.
- The station has full step-free access.
- The station has 697 parking spaces with 18 fully accessible spaces.
The station was built in the 1950s and is a Grade II Listed building.
Train services at the station are as follows.
- Stratford and Bishops Stortford – 2 tph – via Lea Bridge, Tottenham Hale, Waltham Cross, Cheshunt, Broxbourne and Sawbridgeworth
- London Liverpool Street and Cambridge North – 1 tph – via Tottenham Hale, Cheshunt, Broxbourne, Bishop’s Stortford, Audley End, Whittlesford Parkway and Cambridge
- London Liverpool Street and Cambridge North – 1 tph – via Tottenham Hale, Cheshunt, Broxbourne, Roydon, Sawbridgeworth, Bishop’s Stortford, Stansted Mountfitchet, Elsenham, Newport, Audley End, Great Chesterford, Whittlesford Parkway, Shelford and Cambridge
- London Liverpool Street and Stansted Airport – 1 tph – via Tottenham Hale
- London Liverpool Street and Stansted Airport – 1 tph – via Tottenham Hale and Stansted Mountfitchet
Note.
- tph is trains per hour
- The Stansted services are fast services and take 29 minutes between London Liverpool Street and Harlow Town.
- The other services seem to take a few minutes longer.
- London Liverpool Street or Stratford and Tottenham Hale both get six tph.
- Bishop’s Stortford gets a four tph service from Harlow Town.
- The two Cambridge stations only get two tph.
Harlow Town station has a fairly good service, but it could probably be improved.
Harlow Mill Station
This Google Map shows Harlow Mill station to a larger scale.
Note.
- The station has two platforms.
- The station has step-free access to the London-bound platform only.
- The station has 29 parking spaces with 1 fully accessible space.
The station was built in the 1840s and gets about 13 % of the passengers compared to Harlow Town station.
Train services at the station are as follows.
- Stratford and Bishops Stortford – 1 tph – via Lea Bridge, Tottenham Hale, Waltham Cross, Cheshunt, Broxbourne and Sawbridgeworth
- London Liverpool Street and Cambridge North – 1 tph – via Tottenham Hale, Cheshunt, Broxbourne, Roydon, Sawbridgeworth, Bishop’s Stortford, Stansted Mountfitchet, Elsenham, Newport, Audley End, Great Chesterford, Whittlesford Parkway, Shelford and Cambridge
Note.
- tph is trains per hour
- London Liverpool Street or Stratford and Tottenham Hale both get only two tph.
- Bishop’s Stortford gets two tph service from Harlow Mill.
- The two Cambridge stations only get one tph.
Unless you lived or worked nearby, I doubt you would be likely to use Harlow Mill station.
Recent And Planned Improvements
These improvements are planned and it is very unlikely they won’t happen.
Class 710 Trains
London Overground now runs new four-car Class 710 trains between London Liverpool Street and Cheshunt.
- Each has 189 seats and can accept 489 standing passengers.
- Busy services to Cheshunt will probably are pair of trains.
- There are four tph between Cheshunt and London.
- Will the trains shave a few minutes from journey times?
This massive increase in capacity and train quality must attract some passengers to change to and from the London Overground at Cheshunt.
Class 720 Trains
Greater Anglia has 133 new five-car Class 720 trains on order.
- Each has 540 seats and can accept 145 standing passengers.
- They are 100 mph trains.
- Busy services through Harlow will probably be a pair of these trains.
These new trains will be a massive increase in capacity and should attract more passengers to the route.
Class 745 Trains
Greater Anglia has recently introduced ten new twelve-car Class 745 trains on Stansted Express services.
- Each has 767 seats.
- They are 100 mph trains.
- They run a two tph service between Harlow Town and London Liverpool Street station and Stansted Airport.
These new trains should attract more passengers to the route.
Crossrail
Services through Harlow will connect to Crossrail at both London Liverpool Street and Stratford.
Will this mean that some passengers will switch from the Victoria Line to Crossrail for their onward journeys?
- Crossrail will have more capacity than the Victoria Line.
- Bond Street, Canary Wharf, Heathrow, Paddington and West London will be easier by Crossrail.
- Victoria and Waterloo will probably be easier by the Victoria Line.
- London Liverpool Street station’s new connection to the Northern Line will give easier access to parts of South London.
- London Liverpool Street station will have much improved step-free connections to all London Underground lines.
Crossrail will certainly change the way many people travel between Harlow and London.
Four Lines Modernisation
This page on the Transport for London web site explains the Four Lines Modernisation. This is the first paragraph.
We’re transforming the Circle, District, Hammersmith & City and Metropolitan lines. When the work is done we’ll be able to run trains more frequently and reliably to make journeys faster and more comfortable.
The project should increase Peak Hour capacity by 33 %.
This will benefit those who change trains at London Liverpool Street between the West Anglia Main Line and the Circle and Metropolitan Lines.
Possible Improvements
These are possible improvements that may happen.
Crossrail 2
It is unlikely, that a start will be made on Crossrail 2 in the near future.
Victoria Line Improvements
The Victoria Line will continue to do, what it has done reliability for over fifty years.
But there could be improvements.
- Walthamstow Central station will have an additional step-free entrance.
- Highbury and Islington station will become a full step-free station.
- Oxford Circus station will be expanded and become a full step-free station.
I also suspect that engineers will find a way to increase the frequency to forty tph.
Four Tracks On The West Anglia Main Line
There are two reasons for four-tracking sections of the West Anglia Main Line.
- To separate Crossrail 2 trains from fast expresses to Stansted and Cambridge.
- To speed up services to and from Stansted Airport.
However four-tracking the route between Tottenham Hale and Broxbourne stations would probably be very beneficial.
- Stansted Airport and Cambridge services could be speeded up.
- Extra services could be run on the West Anglia Main Line.
- It could make it easier to extend the Overground from Cheshunt.
Four-tracking will be needed for Crossrail 2, so there is surely the possibility, that it could be done earlier to bring benefits to those living along the Lea Valley.
ERTMS Signalling On The West Anglia Main Line
ERTMS Signalling could speed up services and increase their number on the West Anglia Main Line.
It might also enable four-tracking, which would be very disruptive to both train services and road traffic to be delayed.
Station Improvements On The West Anglia Main Line
The stations between London Liverpool Street and Cambridge are a poor bunch with only Tottenham Hale, Northumberland Park, Meridian Water, Waltham Cross, Broxbourne, Harlow Town, Bishop’s Stortford and Audley End having full step-free access.
Some of the other stations need refurbishment and step-free access.
As step-free access will be needed for Crossrail 2, why not setup a rolling program of station improvements.
Level Crossings On The West Anglia Main Line
There are four level crossings on the route to the South of Broxbourne, including three at Cheshunt, Enfield Lock and Brimsdown stations.
They all need to be removed for safety reasons.
New Trains And Capacity
The new trains being rolled out by Greater Anglia and the London Overground will certainly have effects on the services on the West Anglia Main Line.
- The better performance could speed up services by a few minutes.
- The capacity increase on the new trains should be welcome.
- The trains will be of better quality than those they replace.
I also wonder, if the better quality of the trains and their facilities will surely attract more passengers. I suspect the train companies hope so!
Extending The London Overground
This map from cartometro.com shows Cheshunt station and Cheshunt Junction just to the South.
Note.
- The two platforms on the West Anglia Main Line and the single bay platform for the London Overground.
- The level crossing to the North of Cheshunt station.
- The comprehensive Cheshunt Junction which trains to go between the Southbury Loop and the West Anglia Main Line.
Cheshunt Junction is occasionally used by Greater Anglia trains to access the Southbury Loop.
It certainly seems to me, that the Overground could connect to the West Anglia Main Line.
- All trains from London going to the North of Cheshunt could use Platform 2.
- All trains to London coming from the North of Cheshunt could use Platform 1.
- The bay Platform 3 would still be available to turn local trains on the Southbury Loop.
- An extra crossover could probably be inserted to allow trains from London on the West Anglia Main Line to use Platform 3.
London Overground trains could run to a terminal further North.
Trains Between Cheshunt And London
It is worth looking at the number of trains between Cheshunt and London.
- Greater Anglia -2 tph – London Liverpool Street and Hertford East via West Anglia Main Line
- Greater Anglia – 2 tph – Stratford and Bishop’s Stortford via West Anglia Main Line
- Greater Anglia – 2 tph – London Liverpool Street and Cambridge North via West Anglia Main Line
- Greater Anglia – 4 tph – London Liverpool Street and Stansted Airport via West Anglia Main Line
- London Overground – 4 tph – London Liverpool Street and Cheshunt via the Southbury Loop
This means that the West Anglia Main Line has 10 tph and the Southbury Loop has 4 tph.
This suggests possibilities.
- Move some services from the West Anglia Main Line to the Southbury Loop.
- Extend some or all of the London Overground trains to the North of Cheshunt.
- Stations like Bishop’s Stortford, Broxbourne, Harlow, Hertford East and Ware could get extra services to London.
- The new services would connect to extra stations without changing trains.
Very little new infrastructure would be required.
Bishop’s Stortford Station As A London Overground Destination
Bishop’s Stortford station has these trains to and from London.
- Greater Anglia – 2 tph – Stratford and Bishop’s Stortford
- Greater Anglia – 2 tph – London Liverpool Street and Cambridge North
- Greater Anglia – 2 tph – London Liverpool Street and Stansted Airport
Consider.
- Bishop’s Stortford station could probably easily handle up to an extra two tph.
- London Overground’s Class 710 trains only have an operating speed of only 75 mph.
- The trains may need a speed upgrade to serve Bishop’s Stortford, as their speed could slow the Cambridge and Stansted Airport expresses.
If the London Overground services ran to Bishop’s Stortford station, all the smaller stations South of Bishop’s Stortford, could travel to and from Stansted Airport with a single change.
Bishop’s Stortford station may be a possibility, as a destination of two tph on the London Overground route to London.
Broxbourne Station As A London Overground Destination
Broxbourne station has these trains to and from London.
- Greater Anglia -2 tph – London Liverpool Street and Hertford East
- Greater Anglia – 2 tph – Stratford and Bishop’s Stortford
- Greater Anglia – 2 tph – London Liverpool Street and Cambridge North
Consider.
- Broxbourne station could probably easily handle up to an extra two tph.
- As Broxbourne is only 3.2 miles and six minutes to the North of Cheshunt, the 75 mph speed of the London Overground’s Class 710 trains may not be a problem.
Broxbourne station may be a possibility, as a destination of up to two tph on the London Overground route to London.
Harlow Town Station As A London Overground Destination
Harlow Town station has these trains to and from London.
- Greater Anglia – 2 tph – Stratford and Bishop’s Stortford
- Greater Anglia – 2 tph – London Liverpool Street and Cambridge North
- Greater Anglia – 2 tph – London Liverpool Street and Stansted Airport
Consider.
- Harlow Town station could probably easilyhandle up to an extra four tph.
- If one is needed there would appear to be space for a turnback facility or an extra platform.
- As Harlow Town is only 5.4 miles and eight minutes to the North of Cheshunt, the 75 mph speed of the London Overground’s Class 710 trains may not be a problem.
If the London Overground services ran to Harlow Town station, all the smaller stations South of Harlow Town, could travel to and from Stansted Airport with a single change.
Harlow Town station may be a possibility, as a destination of up to four tph on the London Overground route to London.
Hertford East Station As A London Overground Destination
Hertford East station has these trains to and from London.
- Greater Anglia -2 tph – London Liverpool Street and Hertford East
- There is an extra tph in the Peak.
Consider.
- Hertford East station has platforms long enough for eight-car trains and may need modification to accommodate a pair of Greater Anglia’s Class 720 trains.
- Ware station would need to be remodelled to increase frequency above three tph.
- As the route from Broxbourne is on a branch line, the 75 mph speed of the London Overground’s Class 710 trains may not be a problem.
Hertford East station may be a possibility, as a destination of up to two tph on the London Overground route to London.
Conclusion
I think the best two destinations of the London Overground service to the North of Cheshunt would be Harlow and Hertford East.
- Trains could terminate at Harlow Town station to connect with Stansted Express and Cambridge trains.
- It appears that the slightly shorter Class 710 trains may have advantages when using the short platforms at Hertford East station.
Perhaps each destination should receive two tph.
- Harlow Town would be connected to the Overground.
- Passengers using stations between Hackney Downs and Cheshunt on the Southbury Loop would change at Harlow Town to and from Cambridge and Stansted Airport.
