Class 345 Trains And Regenerative Braking
Bombardier don’t seem to talk much about regenerative braking on Class 345 trains.
In the Wikipedia entry for the train, there is a section called Background And Specifications. This is the first paragraph.
In 2008, the UK government’s rolling stock plan stated a requirement for around 600 carriages for Crossrail, expected to be similar in design to the Thameslink rolling stock, to meet the design improvement requirements of the 2007 ‘Rail Technical Strategy’ (RTS), including in-cab signalling/communication including satellite and ERTMS level 3 technologies, regenerative braking, low cost of operation and high reliability, with low weight and high acceleration.
Perhaps Bombardier aren’t letting on how they achieve efficient braking of the trains.
One thing I proved today, was that the trains have no give away electric fires on the roof, where braking energy is traditionally dissipated.
This bad picture was taken through safety netting at Forest Gate station.
The roof is mainly-smooth with just grills for the air-conditioning and ventilation.
There certainly wasn’t any electric fires on the roof!
So does the braking energy get stored on the train for reuse?
