• EMU Preservation

    From Anna Noyd-Dryver@3:633/10 to All on Wednesday, September 02, 2026 11:47:58
    A potentially very significant development in the world of EMU preservation will be announced this afternoon, at 5:07pm (which should give you a clue
    as to what class is currently involved).

    Sorry for the teaser but I just couldn't resist (ahem)

    At least your news is current.

    And direct.

    That's a pretty direct clue?

    https://www.class507.org.uk/2026/09/batteries-included-507001-overpowers-its-third-rail-limitation/

    I was hoping somebody would do a battery conversion - 400V / 800V EV
    batteries are now available for cheap on the salvage market. I don't
    recognise the type of packs they're using - the 'Danger 100V DC' is rather
    odd as even budget cars like the Dacia Spring use 260V packs.

    I believe in this instance, two separate battery packs are being used; as
    yet I'm unaware of their source/origins.

    One large capacity battery at ~110V to power the traction equipment; one
    lower capacity battery at ~600V to power the compressor.

    Some further information from the team involved:

    Four banks in each DM, those in the A car were in series and purely fed the compressor. Those in the B car in parallel and fed the traction motors in
    that car only.

    We were monitoring them throughout, the one thing we weren't monitoring was
    the aux battery, which is what went flat first and called an end to things!

    [ie the battery already installed on the train, which feeds lights and
    control power etc. It's fed from the Motor-Alternator set which they didn't have powered up during this test]

    Ni-Cd at the moment. Currently registering as a charity, once done
    hopefully we can get some grants for a full lithium conversion.

    Now we have proof of concept, we need to do the design work to have the batteries mounted under the trailer.

    Aah, forklift battery packs!

    Ah, that makes sense.

    I was thinking aviation. On ebay the other day I noticed a well used NiCd charger, ex-FlyBe. Presumably for the NiCd pack in the Q400s. But 'folklift'
    is a probably a lot cheaper!

    The nice thing about the 507 is it's been on the juice fairly recently so
    the insulation etc is up to spec, unlike a Mk1 EMU that's been in a field
    for 20 years and will take some recommissioning.
