    ScotRail HST derailment at Dalwhinnie (10/04/2021)

    The one that's been lifted out has classic "wheels running on them" damage on the timbers.

    ScotRail HST derailment at Dalwhinnie (10/04/2021)

    Very strange indeed. This will be one of the more interesting reports.....

    ScotRail HST derailment at Dalwhinnie (10/04/2021)

    Good picture of the signal box diagram at https://flic.kr/p/23UAjdg. There is no signalled move at Dalwhinnie whereby an Up train can get on to the Down line. If I were investigating this, I’d be focussing on how/why that train (or at least, the vast majority of it) was where it ended up. It’s...

    That’s what I’m thinking.

    Triva: Stations with entrances in shopping parades?

    The Argyle Street entrances to Glasgow Central Low Level would also qualify.

    East Kilbride/Barrhead electrification updates

    Existing signalling at Barrhead, while colour light, is worked from a lever frame, so there will be some degree of “resignalling”. The interlocking which currently works the East Kilbride branch is called “BARRHEAD”, presumably with this in mind.

    Booster Transformers - Scotland OLE Work

    Trawling the memory banks here, but isn’t there a feeder at Gowkthrapple (Wishaw South)?

    Least Used Terminating Station

    Not current, but the Carlisle-based Derby Lightweight DMUs had Harker on the destination blind, which struck me as an odd place to terminate a service on a planned basis. Perhaps someone with local knowledge could elaborate?

    East Kilbride/Barrhead electrification updates

    Right! They actually shoved empties in the loop, that was believed to be the most-used ground frame in Scotland.

    East Kilbride/Barrhead electrification updates

    Trawling the memory banks here, but when the Hairmyres loop went in, one of the driving factors was achieving a half-hourly “clockface” service, which simply couldn’t work without it. I think it ran on a 40 minute frequency prior to then.

    East Kilbride/Barrhead electrification updates

    The signalling plan I’ve seen is for full doubling. I would surmise, based on experience, that given that several bridges beyond Busby need to be rebuilt anyway, putting in double track is probably a relatively minor “extra”.

    East Kilbride/Barrhead electrification updates

    Precisely. Area will be resignalled and controlled from WSSC.

    East Kilbride/Barrhead electrification updates

    Easter 2022 is what I’d heard. Not a “Migration” but a resignalling. Barrhead is under the control of a local box.

    Unconventional Signals

    i hadn’t realised that this was the same system as at Mirfield. See https://www.jmri.org/xml/signals/LMS-1932/index.shtml.

    Unconventional Signals

    There was one like that at Alexandra Parade in Glasgow due to it being under a bridge.
