Government Agrees To Fund £200m Cambridge South Station
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
The government has agreed to fully fund a new £200m railway station.
These are a few points.
- Work has already started.
- The station is next to the city’s Biomedical Campus and Addenbrooke’s Hospital.
- Cambridge South station will be on the East West Railway.
It is expected to be open within two years.
I have a few thoughts.
Services At Cambridge South Station
In a typical hour, it seems the following trains go through the proposed site of Cambridge South station.
- 2 tph – Greater Anglia – Liverpool Street and Cambridge North via Tottenham Hale, Cheshunt, Broxbourne, Roydon (1tph), Harlow Town, Harlow Mill (1tph), Sawbridgeworth (1tph), Bishop’s Stortford, Stansted Mountfitchet (1tph), Elsenham (1tph), Newport (1tph), Audley End, Great Chesterford (1tph), Whittlesford Parkway, Shelford (1tph) and Cambridge.
- 1 tph – Greater Anglia -Norwich and Stansted Airport via Wymondham, Spooner Row (1tpd), Attleborough, Eccles Road (1tpd), Harling Road (1tpd), Thetford, Brandon, Shippea Hill (1tpd), Ely, Cambridge North, Cambridge, Whittlesford Parkway and Audley End
- 1 tph – Great Northern – King’s Cross and Ely via Cambridge, Cambridge North and Waterbeach.
- 1 tph – Great Northern – King’s Cross and King’s Lynn via Cambridge, Cambridge North, Waterbeach, Ely, Littleport, Downham Market and Watlington.
- 1 tph – Great Northern – King’s Cross and Cambridge via Finsbury Park, Alexandra Palace, Potters Bar, Hatfield, Welwyn Garden City, Welwyn North, Knebworth, Stevenage, Hitchin, Letchworth Garden City, Baldock, Royston, Meldreth, Shepreth and Foxton.
- 2 tph – Thameslink – Cambridge and Brighton via Royston, Ashwell & Morden, Baldock, Letchworth Garden City, Hitchin, Stevenage, Finsbury Park, St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Gatwick Airport, Three Bridges, Haywards Heath and Burgess Hill
- 1 tp2h – CrossCountry – Birmingham New Street and Stansted Airport via Coleshill Parkway, Nuneaton, Leicester, Melton Mowbray, Oakham, Stamford, Peterborough, March, Ely and Cambridge.
Note.
- tph is trains per hour.
- tp2h is trains per two hours.
This gives a base frequency through Cambridge South, Cambridge and Cambridge North of 8.5 tph.
Could some services be extended to Cambridge South or Stansted Airport?
- 1 tph – Greater Anglia – Ipswich and Cambridge via Needham Market, Stowmarket, Elmswell, Thurston, Bury St Edmunds, Kennett (1tp2h), Newmarket and Dullingham (1tp2h).
- 1 tp2h – CrossCountry – Birmingham New Street and Cambridge via Coleshill Parkway, Nuneaton, Leicester, Melton Mowbray, Oakham, Stamford, Peterborough, March and Ely.
These two trains would gives frequencies of.
- Cambridge South – 10 tph
- Cambridge – 10 tph
- Cambridge North – 9 tph
I have assumed these services would terminate at Cambridge South.
There could also be some new services.
1 tph – Greater Anglia – Wisbech and Cambridge via March, Ely and Waterbeach, Cambridge North and Cambridge.
1 tph – East West Railway – Oxford and Great Yarmouth via Oxford Parkway, Bicester Village, Winsford, Bletchley, Bedford, Tempsford, Cambourne, Cambridge, Cambridge North, Ely, Brandon, Thetford, Attleborough, Wymondham and Norwich.
1 tph – East West Railway – Oxford and Manningtree via Oxford Parkway, Bicester Village, Winsford, Bletchley, Bedford, Tempsford, Cambourne, Cambridge, Newmarket, Bury St. Edmunds, Stowmarket, Needham Market and Ipswich.
These three trains would gives frequencies of.
- Cambridge South – 13 tph
- Cambridge – 13 tph
- Cambridge North – 11 tph
I have assumed these services would terminate at Cambridge South.
The A14 Parkway Station
The A14 Parkway station is a proposal from the East West Railway.
- It would be just to the East of Chippenham junction and would be served by both Greater Anglia’s services between Ipswich and Cambridge and Ipswich and Peterborough.
- It would also be close to the major road junction, where the A11 and the A14 meet.
- It would be a Park-and-Ride station.
I believe it could be a major factor in cutting road mileage in East Anglia, as drivers going to Cambridge from Ipswich, Norwich, a large area of North-East East Anglia and North Essex could find that using the A14 Parkway station an easier and faster route. But the A14 Parkway would need a frequent service to the soon-to-be-three main Cambridge stations.
A Soham and Cambridge service could reverse at the A14 Parkway station or by careful timetabling, passengers would be able to change trains in a minute or two.
A Soham and Cambridge service, that terminated at Cambridge South, would give an extra train between Cambridge South and Newmarket and these frequencies at the three Cambridge stations.
- Cambridge South – 13 tph
- Cambridge – 14 tph
- Cambridge North – 12 tph
There would be a minimum interval of no more than five minutes between trains, if you wanted to hop between any of the three Cambridge stations.
Frequencies between Cambridge station and other main stations in the area would be as follows.
- A14 Parkway – 2 tph
- Attleborough – 2 tph
- Bishop’s Stortford – 2 tph
- Bletchley – 2 tph
- Bury St. Edmunds – 2 tph
- Ely – 6 tph
- Great Yarmouth – 1 tph
- Harlow Town – 2 tph
- Hitchin – 3 tph
- Ipswich – 2 tph
- King’s Lynn – 1 tph
- Letchworth Garden City – 3 tph
- Manningtree – 1 tph
- March – 1 tph
- Needham Market – 2 tph
- Newmarket – 2 tph
- Norwich – 2 tph
- Peterborough – 1 tph
- Royston – 3 tph
- Soham – 1 tph
- Stansted Airport – 2 tph
- Stevenage – 3 tph
- Stowmarket – 2 tph
- Thetford – 2 tph
- Wisbech – 1 tph
- Wymondham – 2 tph
Looking at this list, I think that the timetable needs reinforcing, to perhaps Colchester, Haverhill, March, Peterborough, Soham and Sudbury.
But these services will help.
- 1 tph – Greater Anglia – Ipswich and Peterborough via Stowmarket, Bury St Edmunds, Soham, Ely, Manea, March and Whittlesea.
- 1 tph – East Midlands Railway – Liverpool and Norwich via Liverpool South Parkway, Widnes, Warrington Central, Manchester Oxford Road, Manchester Piccadilly, Stockport, Sheffield, Chesterfield, Alfreton, Nottingham, Grantham, Peterborough, Ely and Thetford
But I can’t help feeling that the Stour Valley Railway needs to be reopened.
Govia Thameslink Railway Issues a Prior Information Notice For New Trains
This article on Railway Gazette is entitled UK Railway News Round-Up and contains this section.
Govia Thameslink Railway has issued a prior information notice seeking the provision of between 21 and 30 four-car 25 kV 50 Hz 160 km/h through-gangwayed EMUs with air-conditioning and toilets for use on existing and/or additional Great Northern services from May 2024. Maintenance would be undertaken in-house at Hornsey depot, supported by a Technical Support & Spares Supply Agreement.
I find this all a bit puzzling.
- The trains that need replacing are surely the eighteen Class 313 trains, that run on the West Coastway Line, as they are some of the oldest trains on the UK network.
- If Govia Thameslink Railway were serious about decarbonisation, they would also replace the Class 171 diesel trains, that work the Marshlink Line and the Uckfield branch, with electric trains with a range of thirty miles on batteries.
How many trains would be needed to replace the Class 313 and Class 171 trains?
- The eighteen three-car Class 313 trains could be replaced with an equal number of new four-car trains and this might result in a rise in passenger numbers.
- I would assume the eighteen trains includes allowances for trains in maintenance and spare trains for when a train fails.
- It may be possible to replace the six four-car Class 171 trains used on the Marshfield Line with three new four-car trains, which have a range of thirty miles on batteries.
- The eleven two-car Class 171 trains used on the Uckfield branch could be replaced with three new four-car trains, which have a range of thirty miles on batteries and would run as four-car trains.
- If eight-car trains were needed on the Uckfield branch, there would be a need for six new four-car trains.
- If twelve-car trains were needed on the Uckfield branch, there would be a need for nine new four-car trains.
Note.
- If four-car trains are needed on the Uckfield branch, this means a total of 18+3+3 or 24 trains.
- If eight-car trains are needed on the Uckfield branch, this means a total of 18+3+6 or 27 trains.
- If twelve-car trains are needed on the Uckfield branch, this means a total of 18+3+9 or 30 trains.
Trains on these Southern routes wouldn’t be stabled at Hornsey depot, but could be moved to Hornsey for maintenance using Thameslink.
But the puzzling bit is that the prior information notice says that the trains will be.
Four-car 25 kV 50 Hz 160 km/h through-gangwayed EMUs with air-conditioning and toilets for use on existing and/or additional Great Northern services from May 2024.
Note.
- There is no mention of the trains being able to run on 750 VDC third-rail infrastructure.
- The trains will run on Great Northern services and the Class 313 and Class 171 trains run on Southern routes.
- The only Great Northern services, that have not been moved to Thameslink are Kings Cross and Cambridge, Ely and King’s Lynn and services to Moorgate.
- The Moorgate services have their own dual-voltage Class 717 trains.
- Govia Thameslink Railway have ambitions to double the frequency of trains to King’s Lynn.
- Two eight-car trains per hour (tph) between King’s Cross and King’s Lynn would need sixteen operational four-car trains.
- Two twelve-car trains per hour (tph) between King’s Cross and King’s Lynn would need twenty-four operational four-car trains.
If Govia Thameslink Railway are thinking of thirty new trains, they must have other destinations in mind.
Could we be seeing a double swap?
- An appropriate number of new trains are procured to run Great Northern services between Kings Cross and Cambridge, Ely and King’s Lynn.
- The Class 387 trains released will be moved to the South to replace the Class 313 and Class 171 trains.
- Some or all of the transferred Class 387 trains will be fitted with batteries to give a range of thirty miles without electrification.
Note.
- Could the new trains be Siemens Desiro City trains like the Class 700 and Class 717 trains, which are already maintained at Hornsey depot? It would surely be more efficient and save money.
- Class 387 trains are dual voltage and would need little or no modification to replace the Class 313 trains.
- Uckfield and Hurst Green junction is 24.7 miles.
- Ashford International and Ore is 25.4 miles
- Adding a battery to a Class 387 train has not been done, but Bombardier converted a near-identical Class 379 train to battery-electric operation over eight years ago.
- Converting a Class 387 train gives a dual-voltage battery-electric train.
- I suspect a charger would be needed at Uckfield. Could it be a short length of 25 KVAC overhead electrification?
Could all the Class 387 trains, that will replace the Class 313 and Class 171 trains be identical to ease the problems, when a train develops a fault?
Conclusion
It looks a good plan.
It also opens up the following possibilities.
- Deployment of 750 VDC battery-electric trains on other routes.
- Deployment of 25 KVAC overhead battery-electric trains on other routes.
- Deployment of tri-mode battery-electric trains on other routes.
- Charging of battery-electric trains using a short length of 25 KVAC overhead electrification.
- Fitting of batteries to Class 379 trains to create a 25 KVAC overhead battery-electric train.
It might be possible to convert other Electrostars to battery-electric operation.
Ignoring Class 387 trains on dedicated services like Heathrow and Gatwick Express, these trains are available for conversion.
- Class 379 trains – Stored – 30 trains
- Class 387 trains – Govia Thameslink Railway – 40 trains
- Class 387 trains – Great Western Railway – 33 trains
Note.
- This gives 103 trains.
- They all have good interiors.
- They are all 100/110 mph trains.
- All trains could be updated to 110 mph.
- All trains can use 25 KVAC overhead electrification.
- The Class 387 trains can also use 750 VDC third-rail electrification.
- The Class 379 trains were built in 2010-2011.
- The Class 387 trains were built from 2014.
I believe both classes will make excellent battery-electric trains.
Where will they be deployed?
These are a selection of routes starting in the South-East of England.
- Ashford International and Eastbourne.
- Gravesend and Hoo.
- London Bridge and Uckfield.
- London Paddington and Bedwyn.
- London Paddington and Oxford.
- Reading and Basingstoke.
- Reading and Gatwick.
- Reading and Redhill.
- Slough and Windsor & Eton Central.
- Twyford and Henley-on-Thames
I’ve only added routes which are less than thirty miles.
Optimal Prediction of Sand For Adhesion
This project was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.
In this document, this is said about the project.
Project No: 10039258
Project title: Optimal Prediction of Sand For Adhesion
Lead organisation: GOVIA THAMESLINK RAILWAY LIMITED
Project grant: £153,228
Public description: Train services are affected by seasonal variables particularly leaf fall between September and
December. They can also be compromised by wet weather, icy and snowy conditions at a regional
or very localised level on a particular route. Maintaining wheel-rail contact to ensure adequate and
safe braking requires the use of sand in low adhesion conditions. Sand is dispensed to trains in
response to a combination of train service plans and of weather forecast. However, not all trains
are currently able to be replenished during overnight stabling and servicing with attendant risks of
delays and damage to trains and infrastructure. Also, there is a high level of safety risk when sand
replenishment on trains is carried out on a third-rail yard.
“Optimal Prediction of Sand for Adhesion” (OPSA) lead by Govia Thameslink Railway, the major
Train Operating Company on third rail in the UK, will deliver a more efficient and cost-effective
means of predicting the dispensing of sand to trains to ensure services are not compromised by
adhesion losses and train sets are not required to be removed from planned operating diagrams
because of inadequate on board sand supplies. The algorithm developed as a results of this project
will base the estimates on an integrated framework that includes the forecast adhesion, track
maintenance and the expected speed profile in order to capture the change in weather and the seasonal factors.
The algorithm developed represents a cost effective solution to predict the use of sand and
schedule the maintenance of trains enhancing in turn safety and reducing the impact of delays on
the timetable. The algorithm will be developed including direct measure of sand dispersion, braking,
wheel slip and line speed diagram also accounting for human behaviour effects such as driving
style.
Govia Thameslink Railway has engaged with Cranfield University to deliver the disruptive
innovation proposed in this project. The algorithm will enable a more efficient train scheduling
improving public performance measure (PPM) addressing train delay targeting in particular the
25% of delay up to 15 minutes cause by several concurrent issues including train rescheduling and
the National Rail Passenger Survey satisfaction.
My Thoughts And Conclusions
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.
Defibrillators Installed At Every Southern And Thameslink Train Station
The title of this post, is the same as that of this article on The Argus.
The title says it all!
It is obviously a good development.
I also think, that there should be instructions by the defibrillator, as to the quickest way to call medical help.
Using Hitachi ABB Power Grids Technology At Uckfield Station
This post describes how the ABB Power Grids technology could be used to allow battery-electric trains to run between London Bridge and Uckfield stations.
The London Bridge And Uckfield Route
The London Bridge And Uckfield route has these characteristics.
- It is forty-six miles long
- The Southern section between Heald Green junction and Uckfield station is 24.7 miles and is not electrified.
- A service takes approximately eighty minutes.
- Trains run at a frequency of one train per hour (tph)
- The route has been upgraded to be able to handle twelve car trains.
- The route is currently run by Class 171 diesel trains.
- Govia Thameslink Railway is the operator.
It looks to me if you assume a ten minute turnround, then that gives a three-hour round trip.
This would mean the following.
- Trains would have ten minutes charging time at Uckfield.
- If twelve car trains were running on the branch then nine four-car trains would be required for an hourly service.
- Two tph would require twice as many trains.
It looks to me, that Network Rail have arranged the route and the timetables for a fleet of battery-electric trains.
The Battery-Electric Trains
There have been several hints in the rail media, that battery-electric Bombardier Electrostars will be used for the London Bridge and Uckfield route.
I wrote Battery Electrostars And The Uckfield Branch in September 2019.
- In the related post I suggested Class 377, Class 379 or Class 387 trains.
- All are four-car Bombardier Electrostars.
- All are 100 or 110 mph trains.
- The Class 387 trains are already dual voltage, but I suspect all trains could be converted to third-rail or dual-voltage.
- My choice would be Class 379 trains, as they are being made redundant by Greater Anglia and thirty quality trains are looking for a new home.
But all three types would be acceptable and Govia Thameslink Railway has both of the other types in its extensive fleet.
Charging The Battery-Electric Trains
This picture shows the single twelve-car platform at Uckfield station.
There would appear to be plenty of space on the side away from the platform.
There would appear to be two main methods of charging the trains.
A Length Of 750 VDC Third-Rail Electrification On The Side Away From The Platform
- The electrification would be long enough to charge a twelve-car train.
- It could even be made very safe, if an interlock were to be provided, that ensured that the third-rail were only to be live, when a train was in the station that needed charging.
This would be possible, but I suspect the Anti-Third-Rail Electrification Mafia will get this simple method stopped.
A Length Of 25 KVAC Overhead Electrification Powered By One Of Hitachi ABB Power Grids Containised Power Systems
The electrification would be long enough to charge a twelve-car train.
The driver or an automated system would raise the pantographs after the train stopped in the station.
Interlocks could be provided to increase safety.
The overhead electrification would be powered by one or more of Hitachi ABB Power Grids’s containerised power systems
Lightweight catenary could be used to reduce visual intrusion.
The curved beam at the top of this overhead electrification gantry is laminated wood.
Because of the higher voltage used, I suspect that the Hitachi ABB Power Grids could charge a twelve-car train in under ten minutes.
GTR And Porterbrook Unveil £55 million Fleet Modernisation
The title of this article, is the same as that of this article on RailNews.
This is the introductory paragraph.
Trains built just five years ago are among those set to be upgraded at Selhurst Depot as part of a £55 million fleet modernisation programme announced by Govia Thameslink Railway and leasing company Porterbrook.
The updates to Class 377 and Class 387 trains, include.
- On-board performance monitoring and fault diagnosis
- Passenger information screens
- USB/power points
- LED lighting
- Passenger-counting technology
- Forward-facing CCTV cameras
I wonder, if the forward-facing cameras will be setup, so that passengers can log in to the video. It would surely, be a way of keeping kids of all ages amused.
Trains are getting more and more like computers on wheels.
Trainspotting At Oakleigh Park Station
Around 1960, my friend; Richard Plumb and myself, used to go trainspotting on the East Coast Main Line through Barnet and Hadley Wood. One of the places, we used to go regularly was Oakleigh Park station, where we would stand on the pedestrian bridge to the North of the main part of the station.
These pictures show the station today.
It hasn’t really changed that much over the sixty years.
- Wikipedia says it was remodelled for the electrification in 1975.
- The steel bridge, where we used to stand i very much the same.
- There are a lot of new houses on surplus railway land.
- The whole area is a lot greener, due to an increase in tree cover of the sides of the railway.
The step-free access is as it was in 1960 and totally non-existent. Wikipedia doesn’t detail any plans for the future.
This Google Map shows the layout of the station.
Note.
- The two island platforms, with four faces.
- The North bridge, where we used to watch the trains.
- The South bridge, which is the station footbridge with steep steps down to the platforms.
It is a station that has most of the things it needs, except for that step-free access!
Could Oakleigh Park Station Be Made Step-Free?
I have to ask this question.
Before I answer it, the following should be considered.
- The station doesn’t appear to have an open Booking Office or any ticket gates, but has ticket machines and Oyster readers on both platforms.
- It also has coffee stalls on both platforms.
- It might be possible to put a lift to Platforms 3-4, but because of the Booking Office, it might be difficult for Platforms 1-2.
- The station has about a million passengers a year.
My personal view is that as more housing is developed between Kings Cross and Welwyn Garden City the train frequency will be increased.
One solution might be to replace the bridge, where Richard and myself, watched the trains, with a new step-free bridge that also bridged Netherlands Road alongside the station.
Did I See Any Trains?
I took this picture of LNER’s new Azuma returning on the first round trip to Leeds.
The Azuma or Class 801 train almost bears a front-end resemblance to Nigel Gresley‘s famous A4 Pacifics. Mallard is a member of this class and set the world speed record for steam locomotives at 126.4 mph.
Although, it is a bit like comparing apples with oranges, it should be noted that Mallard’s speed record is actually faster than the current 125 mph operating speed of the new Class 801 train. But the electric train has another fifteen mph to come with full digital signalling.
But seeing the Azuma coming through Oakleigh Park station, reminded me of summers sixty years ago, when we watched streaks at speed on that same gentle curve.
Should Some Thameslink Routes Be Transferred To Transport for London?
Some commentators and politicians advocate the transfer of some Thameslink services to Transport for London (TfL).
Thameslink has been designed as a single solution to multiple needs, with too much input from politicians worried about losing elections.
Split Fleets And Franchises
If you look at Greater Anglia, Great Western Railway and South Western Railway, who have a similar mix of services as do Thameslink, they have opted for split fleets with short-medium and long distance trains,designed for their tasks.
In the North of England, the short-medium routes are run by Northern and the long distance routes by TransPennine.
Transport for Wales has now split their fleet into three; South Wales Metro, North Wales Metro and long distance.
The Consequences Of Thameslink’s Single Fleet
Services with different needs are using one fleet of Class 700 trains.
Effectively, Thameslink are using a train more suitable for services between St. Albans and Wimbledon stations, on long distance services between Bedford, Cambridge and Peterborough, and destinations along the South Coast.
Going between Brighton and Cambridge stations on an ironing-board seat is not a pleasant experience, as I noted in Observations On Thameslink Between Brighton And Cambridge.
I believe that Thameslink could be split into two; short-medium and long distance routes.
Short-Medium Thameslink Routes
Currently of the twenty-four services planned in the Provisional Timetable, just four are short medium services that run all day.
If we apply the London Overground principle of four tph stopping at all stations, then the Sutton Loop services, are already working to a version of this principle.
Could other services work to the Overground principle?
East Coast Main Line
On the East Coast Main Line, a terminal to the North of Welwyn Garden City station is probably impossible, due to the limited capacity of the Digswell Viaduct.
Welwyn Garden City also has a flyover, so that four tph services to London can reverse in a single platform.
Welwyn Garden City with small modifications should be able to handle four tph on both Moorgate and Thameslink services.
Hertford Loop Line
The Hertford Loop Line services have or could have excellent cross-platform interchanges with Thameslink services at Finsbury Park and Alexandra Palace stations, although they could be improved.
The weak interchange is coming South at Alexandra Palace, which means using a bridge, but it is easy to use Finsbury Park instead.
The Hertford Loop Line also gives access to three terminal stations; Gordon Hill, Hertford North and Stevenage, which could handle four tph.
So could we see Thameslink services using the route?
It would probably need some new six-car trains, which could be shortened from Thameslink’s dreadful Class 700 trains.
Finsbury Park Station
These pictures were taken at Finsbury Park station.
Could a bay platform for Thameslink services by added here?
I suspect that one could, but would it be worthwhile?
Midland Main Line
On the Midland Main Line, in addition to St.Albans City, currently, short-medium distance services terminate at Kentish Town and Luton.
It is a pity, that the Midland Main Line doesn’t have a handy branch!
A Balanced Northern Service
I think for balance that both Northern branches will take an equal number of short-medium distance trains. Perhaps, four tph to two destinations on each branch.
I might choose.
- St. Albans City on the Midland Main Line.
- Luton on the Midland Main Line.
- Welwyn Garden City on the East Coast Main Line.
- Stevenage on the East Coast Main Line via the Hertford Loop.
All services would be four tph.
Southern Destinations
In the South, there are several stations, that could handle four tph.
Traffic will determine which, but I like the claims of Dartford, East Croydon, Orpington and Sutton on the Wimbledon Loop.
Transfer To London Overground
These short-medium distance routes should be transferred to the London Overground.
It should be noted how if the Moorgate services are also transferred to the London Overground, as I outlined in Should The Moorgate Lines Be Transferred To Transport for London?, then the following frequencies would apply.
- 8 tph – Alexandra Palace to Welwyn Garden City
- 12 tph – Alexandra Palace to Gordon Hill
- 8 tph – Gordon Hill to Hertford North
- 4 tph – Hertford North to Stevenage.
There would be 20 tph between Finsbury Park and Alexandra Palace.
With ETCS, I don’t think that last frequency would be unrealistic, as there are two separate lines in each direction between the two stations.
Long Thameslink Routes
Class 700 Trains
These are currently, a disaster for passengers, as travelling between say Brighton and Cambridge in the dreadful Class 700 trains, is possibly the worst train journey in the UK in new train. In some ways Pacers are better!
This article in the Express is entitled ‘One Is Not Amused’ The Queen Is Not Happy With Changes To Trains, Claims Rail Boss.
If the Royal Posterior finds them hard in First Class, the seats must be dreadful there too!
But it’s not just the passengers who don’t like them.
I came back to London recently with a group of East Midlands Trains drivers. Their professional view of the Class 700 trains, is that they are not fast enough with an operating speed of 100 mph, as against the 125 mph of the trains run by East Midlands Trains.
It should be noted that on the East and West Coast Main Lines, the semi-fast medium-distance services are generally run by 110 mph trains.
So I feel very strongly, that the Class 700 trains are not only bad from the customers point-of-view, but totally unsuitable to run services on the Midland and East Coast Main Lines, where all other trains can cruise happily at 125 mph.
They must be assigned to more suitable duties!
The Routes
Get some new trains on these routes designed by people with sense and style and the routes would be transformed.
I also think, that the destinations served South of the Thames should be simplified. Thameslink is trying to serve too main destinations in the South, compared to the North, where long distance routes only serve Bedford, Cambridge, Peterborough and the intermediate stations.
Perhaps, there should be more services linking from all along the South Coast to an improved rail station at Gatwick Airport.
An Airport Route
I have travelled to and from Gatwick Airport several times, since Thameslink reopened through London Bridge a few months ago.
Outside of the Peak, these trains may be busy between London Bridge and Gatwick stations, but in the Central Core, passengers are fairly thin on the uncomfortable seats.
Luton Airport have been campaigning for more services and I suspect Gatwick would like more too.
So why not run a four tph service between the two airports, using well-designed airport trains?
An Increased Frequency Through The Core
Thameslink is currently planning twenty-four tph through the core tunnel, but there are statements that thirty tph could be handled.
The destinations to handle the extra trains exist in the South, especially, if routes out of London Bridge are replaced by Thameslink services, but accommodating more services on the East Coast and Midland Main Lines could be tricky.
Conclusion
I believe it is possible to split Thameslink into two sections.
Long distance services with new trains would stay with National Rail, but short-medium services would go to the London Overground and probably be run by six and eight-car versions of the existing trains.
Should The Moorgate Lines Be Transferred To Transport for London?
This article in Rail Magazine, is entitled TfL Targets Transfer Of Govia Thameslink Services.
One of the services, targeted by Transport for London (TfL) are the Great Northern services into Moorgate station from Hertford North, Stevenage and Welwyn Garden City stations.
I know the line into Moorgate and the various branches well, as I’ve used them in different forms, since I was about eleven.
The section between Moorgate and Finsbury Park stations is often referred to as the Northern City Line.
I wrote about these lines in a series of posts linked to A North London Metro.
The biggest problem, I find with the lines, is the quality of the trains and the stations. But there are other issues that will also effect these services, which I detail in the following sections.
Trains
The current Class 313 trains are some of the oldest on the UK rail network, as they were built around 1976, which makes them only a couple of years older than London Overground’s Class 315 trains.
I ride in both fleets regularly and although both show their age, those on the Overground appear to have had a lot more TLC.
It’s almost as if GTR doesn’t care about the Northern reaches of their Network.
In some ways, when the Lea Valley Lines were managed by Greater Anglia from Norwich, it was the same Out-Of-Site-Out-Of Mind attitude.
Both operators are changing these elderly fleets by the end of next year.
- London Overground’s Class 315 trains with new Class 710 trains.
- GTR’s Class 313 trains with new Class 717 trains.
My worry about moving the Moorgate services to the London Overground would be about the transfer of the new trains, although TfL do have some cards in their favour.
- The Class 717 trains are designed for the rather unusual operating conditions of the Northern City Line.
- Siemens have a contract to build and maintain the Class 717 trains.
- TfL have recently signed a big deal with Siemens, for the New Tube for London.
- The current Class 313 trains are single-manned.
I would hope that the trains and their crews would not be too difficult to transfer to the London Overground.
Stations
Many of the stations like Essex Road are tired and need serious work, which would start with a good deep clean. Is it the same Out-Of-Site-Out-Of Mind attitude?
Highbury & Islington Station
These pictures show Highbury & Islington station.
The decor needs a serious refresh.
If I want to go to say Hertford North or Welwyn Garden City, the easiest way is to go via Highbury & Islington station and get a direct train.
Until a few months ago, there used to be no way to buy a ticket at the station.
- The destination is outside my Freedom Pass area.
- I can’t use Oyster or contactless card at the destination.
- There is no ticket machine to buy a ticket.
- There is no ticket office.
However, the latest Underground ticket machines have solved the problem
When you consider that Highbury & Islington station is the fourteenth busiest station in the UK and that it handles more passengers in a year, than Cannon Street, Charing Cross, Edinburgh Waverley and Manchester Piccadilly, the station is a disgrace.
Are other stations as passenger unfriendly?
Crossrail
Crossrail will seriously affect the services into Moorgate station.
Consider the following.
- Changing to and from Crossrail at Moorgate will become a preferred route for many passengers.
- Moorgate is a short walk to much of the City of London.
- Moorgate and Liverpool Street will be one massive interconnected station.
- The new Class 717 trains will attract passengers, if they are better than Thameslink’s terrible Class 700 trains.
- Between Moorgate and Alexandra Palace stations could have a frequency as high as twelve trains per hour (tph), that runs all day.
- The Victoria Line doesn’t connect to Crossrail, but it does have a cross-platform interchange at Highbury & Islington station with the Northern City Line.
- The Piccadilly Line doesn’t connect to Crossrail or serve the City of London, but it will soon have a much-improved connection to the Northern City Line at Finsbury Park station.
Predicting the number of passengers on the services into Moorgate will become one of those classic extremely-difficult multi-variable problems.
Journeys Will Change
As an example of a changed journey take the case of someone living in Walthamstow wanting to go to Heathrow.
Currently, the easy route is.
- Victoria Line to Finsbury Park – 9 minutes
- Piccadilly Line to Heathrow Central – 64 minutes.
This is a total time of 73 minutes.
After Crossrail opens the high-frequency route will be.
- Victoria Line to Highbury & Islington – 12 minutes.
- Northern City Line to Moorgate – 10 minutes.
- Crossrail to Heathrow Central – 33 minutes
This is a total time of 55 minutes.
Thameslink
Thameslink hasn’t been designed with improving the local services on the East Coast Main Line in mind and GTR are hoping that the new trains to and from Moorgate, will provide enough capacity.
As it might be hoped that the new trains on the Moorgate services will be an improvement on the dreadful Thameslink Class 700 trains, with ironing board seats and no wifi, power sockets or tables, will passengers be swapping their London terminal to Moorgate with its better trains and connections?
Hertfordshire
Thirteen of the thirty-one stations served from Moorgate are in Hertsfordshire.
What will that County Council’s reaction be to a transfer of the Moorgate routes to the London Overground?
Relationship With The Underground And Overground
The route between Finsbury Park and Mootgate stations used to be part of the Underground and there are several interchanges between the route and the Underground and Overground.
- Bowes Park station is an out-of-station interchange with Bounds Green station on the Piccadilly Line.
- Harringay station is an out-of-station interchange with with Harringay Green Lanes station on the Gospel Oak to Barking Line.
- Finsbury Park station is an interchange with the Piccadilly and Victoria Lines.
- Highbury & Islington station is an interchange with East London, North London and Victoria Lines.
- Old Street is an interchange with the Northern Line.
- Moorgate is an interchange with the Circle, Hammersmith & City, Metropolitan and Northern Lines, in addition to Crossrail from the end of this year.
When the new Class 717 trains, with their increased frequency of at least four tph, start running, it will be a new high frequency Metro for the London boroughs of Barnet, Enfield, Haringey and Islington.
Future
I can see various changes adn additions to this line in the future.
ETCS On The East Coast Main Line
ETCS is being installed on the East Coast Main Line to increase capacity. It would appear that trains running to Welwyn Garden City station, will need to have ETCS installed.
As the new Class 717 trains are similar to the Class 700 trains, which use ETCS in the Thameslink core between St. Pancras and Blackfriars stations, fitting the system to the trains, shouldn’t be a problem.
But fitting ETCS to all the Class 717 trains, would mean that installing and using ETCS on the routes into Moorgate station would not be a difficult enterprise.
If this were to be done, would trains between Moorgate and Finsbury Park stations be able to attain the Thameslink frequency of twenty-four tph?
I can’t see why not!
Faster Running On The East Coast Main Line
In Call For ETCS On King’s Lynn Route, I talked about an article in Edition 849 of Rail Magazine, with the same title, where I said this.
In addition to ETCS, which could improve capacity on the East Coast Main Line, they would also like to see journey time reductions using trains capable of running at 125 mph or faster on the King’s Lynn to Kings Cross route.
Faster limited-stop 125 mph trains from Cambridge, Kings Lynn and perhaps, Peterborough to King Cross would surely increase capacity and might even help with the double-track bottleneck of the Digswell Viaduct.
One of the problems is that Thameslink’s Class 700 trains are only capable of 100 mph.
They are just not fast enough.
With 125 mph running limited stop into Kings Cross or Thameslink, will this free up capacity on the slow line and perhaps allow extra services from London to Welwyn Garden City station. They can’t go further North because of the Digswell Viaduct, unless the trains use the Hertford Loop Line.
I’m pretty certain that introducing 125 mph trains to Cambridge, Kings Lynn and Peterborough could open up more csapacity for services on the Great Northern route.
Increased Capacity At Moorgate
Crossrail will connect to the routes into and through a rebuilt Moorgate station.
- This connection will attract more passengers.
- Crossrail provides connection to Canary Wharf, the West End, Paddington station and Heathrow.
- The rebuilt station will also provide high-capacity step-free connections to the Central, Circle, Hammersith & City and Northern Lines.
- There will hopefully be better access to walking routes through the City of London.
Looking at the plans for the massive double-ended Liverpool Street-Moorgate station on Crossrail, it would appear that, the station complex is being rebuilt for a large increase in passengers.
Currently, the frequency to and from Moorgate station is around ten tph, which is handled on two platforms.
Consider.
- Brixton and Walthamstow Central stations on the Victoria Line, handle 36 tph with two platforms and Automatic Train Operation (ATO).
- The East London Line will be handling twenty tph Between Dalston Junction and Surrey Quays stations, by the end of next year.
- The Class 717 trains will have a better performance than the current Class 313 trains.
- The signalling could probably be updated and ATO added as I indicated earlier
I would suspect that a frequency upwards of at least sixteen tph to and from Moorgate could be possible.
I’d like to know, what capacity was assumed in the design of the rebuilt Moorgate station, to make sure, the station was future-proofed for all possible services.
Increased Frequencies
All stations between Liverpool Street and Shenfield have had a frequency of ten tph, as long as I can remember and this frequency will be increased to twelve tph, when Crossrail opens.
Alongside this, the frequencies of four tph to and from Hertford North and Welwyn Garden City look measly!
The Hertford Loop Line has three possible terminals; Gordon Hill, Hertford North and Stevenage, all of which could handle four tph. If all were used, this would give these frequencies.
- 12 tph – Finsbury Park to Gordon Hill
- 8 tph – Gordon Hill to Hertford North
- 4 tph – Hertford North to Stevenage.
If what I said earlier is correct and that sixteen tph is possible into Moorgate, then this would still allow the current frequency of four tph to Welwyn Garden City.
Twenty tph into Moorgate would allow an increased frequency of eight tph to Welwyn Garden City, which would match the frequency to Hertford North.
Park-And-Ride
There is a need for at least one parkway station on the Great Northern route.
GNER were intending to provide one at Hadley Wood station.
Parliament held a debate in January 2000 about this and you can read the debate here on the Parliament web site. Generally, MPs were not in favour.
Stevenage has also been proposed for a parkway station and I think this is much more likely.
Incorporation Into The Tube Map
There will soon be calls for the Southern part of the route to be shown on the Tube Map.
Conclusion
I can see serious investment will be needed at stations on the Great Northern route and especially on the deep-level Northern City Line.
It is also likely, that more trains could be needed. Especially, if twenty tph were run through to moorgate.
Do GTR have the will and the resources to invest in this line?
I doubt it, as it is probably seen as an irrelevant backwater, by GTR’s so-called management.
Given the close connection of this route to Crossrail and the Underground and that fifty-eight percent of the stations are in Greater London, then Transport for London would seem to be an ideal owner for this route.
