    Most effort/work spent on a railway project that ultimately never happened?

    Singling of Kilmarnock-Annan. Got as far as cable being laid and relay rooms being built. The contractor realised that they had hopelessly underbid it and asked to be released just as BR (ScR) was realising what a mistake they’d made, so a win-win!

    Paired by use or paired by direction

    Ah, the old "paired by direction" and "paired by use" thing. Basically, different railway companies had their own preferences. Example: the ECML four-track sections have both Ups together, whereas the GW is Slow (or Relief) together.

    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...

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

    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.

    Flexity Strip track circuits

    The TI21 equipment had the same style of housings as the Aster gear. It was essentially an AC-immune version of the Aster.

    Flexity Strip track circuits

    42 years and counting here, and it’s not a term I’ve ever heard. Suspect it’s some sort of bond.

    Rail Operating Centre reliabilty

    Not wishing to get too far OT, but I recall that Victoria was GEC, as it was then known, as they were robbing stuff (particularly FDM equipment) from there for Edinburgh. 1614647584 I recall that when the standby generator for Dundee SC was tested pre-opening, the CCTV picture for Camperdown...
