This does beg the question as to why. (Apologies if answered in the video)

What is it for?

Interesting, wonder if it's provided any useful results?

I don't see how it will give better energy retention than regen braking and a battery set. But that is the point of experiments after all

 

I understand that it was testing the concept of recycling the energy from braking, but I can't work out where a powered DVT would be useful in practise?

 

Presumably if it is in a known NR-approved package it's that bit easier to move it round the network to accumulate testing data.

 

If I remember, it was to investigate using that energy when the set moves off from a standing start which is when its at its least efficient and most carbon producing.
