London Underground’s New Piccadilly Line Trains Delayed Until 2026
The title of this post, is the same as that of this article on Railway Gazette.
These are the first two paragraphs.
The new air-conditioned trains which Siemens Mobility is supplying for London Underground’s Piccadilly Line are now expected to enter service from the second half of 2026, Transport for London has confirmed.
When the order was signed in November 2018 it was envisaged that the trains would enter service from 2024.
The article also says this about the new CAF trains for the Docklands Light Railway.
The Docklands Light Railway is to implement ‘short-term timetable changes’ on less busy routes from July 21. The reduction in services aims to ensure that reliability can be maintained pending the delayed introduction of new CAF trainsets, which was originally planned for 2023 but is now expected later this year. TfL said the age of the existing trains meant some needed to be retired this summer.
It looks like has two sets of new trains, both being delivered two years late; one being German and the other Spanish.
The only factors I can think both trains being late would be.
- Bad management of the contracts by Transport for London.
- Bad documentation of the Piccadilly Line and the Docklands Light Railway, when they were built.
- Bad project management generally throughout Europe.
- All politicians will be blaming someone else.
Take your pick!
Could A Cross-City Underground Railway Be Run Using Battery-Electric Trains?
Consider.
- Cross-city underground railways like London’s Bakerloo, Central, Jubilee,Northern, Piccadilly and Victoria Lines are usually powered by third-rail technology, which can be dangerous, if someone falls on the track.
- Siemens new London Underground 2024 Stock, which is fully-described in this Wikipedia entry, has the following characteristics.
- A train width of 2.648 metres.
- A train height of 2.844 metres.
- Walk-through carriages
- Air-conditioning
They will also have batteries to support regenerative braking.
But say you were building a new underground line across a city like Birmingham, Leeds or Manchester.
Would the following be possible?
- The tunnel would be built as small as possible, which would probably mean that it was built faster and more economically.
- There would be no electrified rails or overhead wires to power the trains in the tunnel.
- The trains would be powered by batteries.
- Batteries would be charged by a pantograph, that erected to contact with an overhead line outside the tunnel.
- The central tunnel would be bored straight.
- When the train doors opened, passengers would be able to walk on a level surface into and out of the train.
- I believe it would be possible to align the train doors with openings in the tunnel wall at stations to eliminate the need for platform edge doors.
I believe that to design a train and tunnel to literally fit like a glove, could save a lot of money on building a cross-city underground line.
The New Southbound Northern Line Platform At Bank Station
These pictures show the new Southbound Northern Line Platform at Bank Station.
Note.
- This is probably London Underground’s newest platform.
- The step into and out of the train is fairly level.
- This improvement has been achieved with new track and thirty-year-old rolling stock.
Have Siemens redesigned the platform/train interface in the London Underground 2024 Stock, so that the train/platform interface is even better?
- Who’s to know what you can do with modern computer-aided design techniques?
- If the train were to be battery-powered, so that conductor rails were not needed, would the extra space help fit everything in?
- If there were no live rails under the train, would this increase safety, both real and perceived?
I believe it might be possible to design a train/platform interface, that would work with simpler and more affordable platform edge doors.
We probably find out what is possible until the London Underground 2024 Stock enter service later this year.
