An Analysis Of Waterloo Suburban Services Proposed To Move To Crossrail 2
I wrote this post in January 2017, when I decided to cut this out of my original post of A Hard Look At Crossrail 2.
Nearly two years later, I decided to update the post after the new platforms have reopened at Waterloo station.
I wrote Is This One Of The Best Platform Access Routes In Europe?, after the access to the new platforms was substantially completed in May 2019.
This has meant a further upgrade has been incorporated.
The Waterloo Suburban Services Proposed To Move To Crossrail 2
These suburban termini and their routes into Waterloo station are proposed to be connected to Crossrail 2.
- Chessington South – 34 minutes – 9 stops
- Epsom – 37 minutes – 9 stops
- Hampton Court – 36 minutes – 9 stops
- Shepperton – 51 minutes – 14 stops
The times are for a typical one-way journey from Waterloo, which usually has a frequency of two trains per hour (tph).
I suspect that the timings are designed, so that they can be achieved by a 75 mph Class 455 train.
An Upgraded Waterloo Station
Waterloo station is getting a massive upgrade in August 2017, which I describe in detail in What Is Happening At Waterloo In August?.
That upgrade has now opened and is now substantially complete in May 2019.
After the upgrade, Waterloo station will handle the suburban services better than it does today.
- There will be five extra platforms, with the reopening of the platforms 20 to 24 in Waterloo International.
- Together these platforms should be able to handle another twenty tph.
- There will be longer platforms, which will all be able to take twelve-car trains.
- There will be an improved track layout, both in Waterloo and on the approach.
- There will be related improvements to improve access to the Underground and the Waterloo and City Line at Waterloo station.
All this should mean Waterloo station, will be capable of handling a substantial increase in trains and passengers, with an improvement in efficiency and comfort.
As I said in Rail Engineer On New Platforms At London Waterloo, the number of passengers handled in a year will increase by twenty-five percent.
Improvements On The Branches
Each branch has its own problems, but the following would help in various places.
- More step-free access.
- Some level crossings on the branches can probably be removed..
- Improved access to onward services like buses, cycling and walking at some stations.
- Some trackwork to allow Crossrail 2’s proposed frequency of 4 tph.
These improvements will generally be needed, whether the services terminate in Waterloo or are a part of Crossrail 2.
New Trains
Currently, suburban services out of Waterloo are run by a large mixed fleet of generally excellent trains.
- 127 Class 450 trains – 100 mph – Entered service in 2003.
- 137 Class 455 trains – 75 mph – Entered service in 1982.
- 30 Class 458 trains – 100 mph – Entered service in 2000.
- 30 Class 707 trains – 100 mph – Entering service in 2017.
This gives 264 four-car trains and 60 five-car trains with a total of 1137 carriages.
South Western Railway are purchasing 30 five-car and sixty ten-car new Aventras with a total of 750 carriages.
The Class 707 trains and the Aventras could offer serious performance improvements, as they are probably designed to be able to have a short as possible time, for a stop at a station.
In an ideal world, all trains running these branches would be identical and all platforms would be designed to fit them perfectly, just as many Overground platforms, fit the Class 378 trains.
Crossrail 2 would do this, with possibly the same Class 345 trains, that have been developed for Crossrail.
But why shouldn’t the routes be worked by a homogeneous fleet, serving platforms and stations designed for the trains?
I believe that Crossrail 2 could make no extra difference to the passenger going between these branches and Central London, except for the route from Wimbledon, which will be in tunnel.
But the new Aventra trains will have three very big effects.
- They will be walk-through ten-car trains.
- They will have much better capacity for bags, cases and all the other paraphernalia passengers bring.
But most importantly, if they live up to the claims of train manufacturers, the high performance, well-designed trains with a consistent train-platform interface will save as much as three minutes a station.
- Trains will stop from line speed faster.
- Trains will accelerate back to line speed faster.
- Bigger lobbies, will enable passengers to load and unload faster.
- Wheelchair passengers and buggy pushers would roll across on the flat.
- Regenerative braking and light weight will save the train operating company in electricity and train access costs.
Until we get actual figures, even one minute a stop, would reduce times on the branches as follows. Figures in brackets are for two minutes a station.
- Chessington South – 25 minutes (16)
- Epsom -28 minutes (19)
- Hampton Court – 27 minutes (18)
- Shepperton -37 minutes (23)
Note that the first three services are now under half-an-hour, without making any allowance that the timings will be for a 100 mph train with better performance, than the 75 mph Class 455 trains.
Is Four Trains Per Hour Possible?
If the round trip from Waterloo can be done in an hour, that means that just two ten-car trains can provide a 2 tph service, as opposed to the four trains now needed.
I suspect that South Western Railway will be experimenting to see if they can get a Shepperton round trip in under the hour.
It may seem difficult, but there are certain factors in their favour.
- The Shepperton Branch Line is self-contained after it leaves the Kingston Loop Line.
- It is double-track, so there is no passing loop problems.
- There are no level crossings.
- The stations on the branch are fairly evenly-spaced at just over a mile apart.
If a total out-and-back time from Waterloo could be under an hour for each branch, this would mean that a 4 tph service on a branch, would need just four trains.
So for each branch to have 4 tph would need just 16 ten-car trains, with similar performance and characteristics to Class 707 trains or the Aventras.
Currently, to provide a 2 tph service, needs sixteen trains, because it takes over an hour to do a complete round trip.
Would it be possible for trains to shuttle up and down these branches?
Look at the example of the East London Line, where four tph shuttle between dedicated platforms at Highbury and Islington and Dalston Junction stations in the North of London to various destinations in the South.
In Increased Frequencies On The East London Line, I reported on Transport for London’s plans to up the frequency on this line to 20 tph.
So could we be seeing something similar at Waterloo, where trains to Chessington South, Epsom, Hampton Court and Shepperton stations, each have their own dedicated platforms?
The four platforms could even be adjacent, so if you want Wimbledon or a station common to more than one branch, displays would lead you to the first train.
Put simply to provide 4 tph for all branches would need 16 modern ten-car trains and four dedicated platforms at Waterloo. How efficient is that for passengers and train operating companies?
Crossrail 2’s Proposals For Services On The Branches
Wikipedia says this about Crossrail 2 services to these suburban branches, after surfacing from the tunnel South of Wimbledon station.
- 20 tph at Raynes Park
- 8-10 tph at Motspur Park
- Exclusive use of the Chessington Branch Line to Chessington South (4 tph)
- Mixed use of the Raynes Park – Epsom Line to Epsom (4-6 tph)
- 10-12 trains per hour at New Malden
- Exclusive use of the Hampton Court Branch Line to Hampton Court (4 tph) with interchange at Surbiton
- Shared use of the Shepperton Branch Line with 6-8 tph to Teddington and 4 trains per hour to Shepperton
I think that Wimbledon will have to handle perhaps another 8 tph from other places on the fast lines. But they do that now!
Between Wimbledon And Waterloo
South Western Railway have not disclosed their hand yet, but I suspect that they are doing the maths.
I think that it will be possible for a 4 tph Crossrail 2 service and all the other slow services between Wimbledon and Waterloo to use a single pair of tracks carrying 20 tph.
Surely, if 20 tph can be handled on the East London Line with ten year old signalling technology and Class 378 trains, then this frequency can be handled with modern signalling and new Aventras.
It should be noted that Crossrail and Thameslink can both handle 24 tph under Automatic Train Operation (ATO) in a tunnel, so surely the slow lines can handle 20 tph on the surface under ATO or just using plain good driving.
There could even be capacity for some extra services.
Wimbledon Station
Wimbledon station would only need two platforms for these services, but I do feel that work would need to be done to accommodate the passengers.
But the station would probably not need the massive modifications until it was decided to build the Crossrail 2 tunnel.
Clapham Junction Station
If all these trains can be accommodated on just two tracks between Waterloo and Wimbledon, then these services could call at two dedicated platforms at Clapham Junction station.
- All trains would stop.
- Staff and passengers would see a succession of identical trains stopping every three minutes.
- Passengers would have a maximum wait for fifteen minutes for a direct train, to their specific destination.
- All trains to stations on the branches would use the same platform, making it easy for passengers.
- As on the East London Line, trains for any station on the branches would be to a clock-face pattern.
The two platforms could be opposite faces of an island platform, with a waiting room, cafe and toilets in the middle.
Vauxhall Station
If it can be done at Clapham Junction station, why not have a dedicated pair of platforms at Vauxhall station, giving access to the Victoria Line?
I use the link at Vauxhall, between the Victoria Line and Waterloo suburban services occasionally and every time I do, it seems to have been improved.
This map from carto.metro.free.fr shows the lines at Vauxhall station.
I think it is true to say, that if the Victoria Line had been built in the last decade or so, the Victoria Line station could have been placed underneath the main line station.
But even so, I suspect Network Rail and Transport for London have ideas to improve the interchange.
Only Sixteen Ten-Car Aventras Will Be Needed
My calculations show that modern 100 mph trains, like the Aventras that South Western Railway have ordered could provide 4 tph on the Crossrail 2 routes with just sixteen ten-car trains.
All the calculations I’ve done show that replacing trains with faster modern ones, increases the frequency and results in more efficient use of trains.
South Western Railway have bought sixty of these trains.
So they must have some impressive plans!
Conclusion
Crossrail 2’s proposals for the suburban branch lines from Waterloo to the four destinations of Chessington South, Epsom, Hampton Court and Shepperton stations, can be fulfilled using the following.
- More platform capacity in Waterloo.
- Modern high-performance 100 mph trains like Class 707 trains or Aventras.
- Some improvements to track and signals between Waterloo and Wimbledon stations.
- Wimbledon station would only need minor modifications.
- A measure of ATO between Waterloo and Wimbledon stations.
