    As vivarail has found a way to powering a 484 using forklift batteries, prehaps thats an avenue to explore, i'm not sure how big they are, or how many it would take, but it should be more cost effective than installing a raft of battery packs.

    We're watching what Vivarail are doing with the 484 deliveries with great interest. But we have also got a quote for doing it properly with a raft of battery packs.

    Oh well, that's the obvious if slightly dull explanation then. A shame really, I was hoping for some pioneering preserved 4th rail action. (Still, I've toured the Northern Line on the LT Museum's example.)

    Good luck with your project.

    And where could you put 500 HP2 batteries in line? In the grab rails of course! These tube train designers thought of everything.

    Energy capacity ~ 20 Watt-hour per cell x 500 = 10 kWh, so you could run the train for several minutes.;)

    Given its only a couple of stops, I wonder how much a suitcase generator continuously running could top it up?

    No, the air compressors would flatten them before you got it up to pressure.:)

    I suppose the question is where could you fit the batteries all the control gear, etc is under floor mounted, so really it would mean the batteries would have to go inside the vehicles somewhere,

    Now, here's a question, what is under the seats? for instance if some of the seating bays are empty cases, could these be turned to battery storage locations, with suitable ventilation ports etc, and of course outwardly looking, you wouldn't know it, as it would retain the original appearance. spread between the two cars, with suitable connectors and wiring between the coaches and a shore line plug in point faired into the body shell on each car to allow charging . Is there any risk to passengers if a unit is modified in this way?

    I recall working 483 001 from Winchester to Eastleigh after it had worked it's inaugural test run from Eastleigh works without a guard.
    The front cover of the seating bench had been removed and there were a series of wire pully's to open/ close the door.
    The main thing I recalled about that trip, only platform three at Eastleigh could be used and there was a points failure so we were stuck outside
    Eastleigh for about an hour.
