    Brilliant.

    Where are the batteries and what technology are they? I'd sooner see one of these than another Pacer...

    Excellent news!

    As well as making it suitable for operation, does that mean it can be stored with the power still on, and avoid the problems a lot of MUs get when sat unpowered?

    If you take it to the Spa Valley, could you plug it into their carriage shed solar panels and become a zero-carbon operation?

    I guess this means it's no longer going to Tanat Valley?

    You have batteries underneath and tow a 750v generator to keep it topped up so you have spare power on tap for rapid acceleration and increased passenger loading.

    There are precedents for something like that. Some examples in this paper:

    https://applrguk.co.uk/media/files/lruk lrapplrgelectrictractionbeyondthewiressm-jh v.11 08 11.pdf

    In particular, in 1930s Argentina, some suburban passenger services began to be operated by EMUs that obtained their electric power from an attached "mobile power station" vehicle. Imagine a Hastings DEMU where the diesel engine and electric generator are housed in a separate vehicle instead of within a passenger carriage.
