London’s Trains With Built-In Energy Storage
I took this picture at Blackhorse Road station on the Victoria Line.
London’s Trains With Built-In Energy Storage
Since it opened in 1968, all trains have had built-in energy storage to save energy. Under Design in the Wikipedia entry, this is said.
Each platform constructed specifically for the Victoria line from new is 132.6 metres (435 ft) long. The line has hump-backed stations to allow trains to store gravitational potential energy as they slow down and release it when they leave a station, providing an energy saving of 5% and making the trains run 9% faster to a speed of 87.2 km/h.
I wonder if Crossrail and other lines use this technique.
Dear old Vicky, may be just two years off fifty, and some things may have been skimped in the construction, but some features of the line can’t be described as anything but the best of designs.
The Anonymous Widower 
Not an entirely new idea even in the 1960’s see: –

and
https://en.wikipedia.org/wiki/Central_London_Railway#Construction.2C_1896.E2.80.931900
where the technique was used in the 19th Century
Crossrail may have used this, but electrical regeneration may be easier.

Not sure why there are two comments. The first attempt was discarded.
