    Bonus mileage for the Edinburgh punters who have been given an hours tour of Abbeyhill Jn after it didn’t/couldn’t stop at Waverley.

    Someone has also posted on twitter that they are on that service.

    No food, toilet won’t flush, shower doesn’t work and the staff are shouting at each other

    Driver apparently reported to the signaller that he couldn't bring the train to a stand while between Haymarket and Waverley, train sailed through Waverley with the route set accordingly and stopped near Craigentinny. Bizarre state of affairs.

    The brakes themselves would have worked. They just couldn’t be activated due to an operating error earlier in the journey, which is now under review.

    All rectified now, and the train arrived back at Edinburgh at 0844. Still a highly regrettable turn of events.

    Given RAIB is involved perhaps further discussion/speculation about what has or hasn’t happened this morning should wait...

    If there is one positive, it is that RAIB will have good poke at the brakes situation on the MK5s.

    Will this not require the various takes to all be pulled to be checked ? Failed brakes is not a good one ...

    Aren't braking systems supposed to be failsafe - ie an operating error ought to mean that they can't be released rather than that they can't be applied?

    Isn’t 92020 the one that’s just entered service following a huge rebuild/refurb?

    And was faultless for me between Carstairs and Edinburgh on Saturday morning, not to mention splendid looking in its GBRf livery

    I don't believe so, that was 92006:

    Though 92020 did undergo an extensive restoration during 2018 after being out of use since 2001.

    Staff are now gathering at west end of train, presumably waiting for loco to run back

    It was 92006 that’s just entered service not 020.

    020 was what was supposed to be at the helm of my cancelled trip last month which is why it was stuck in my head.

    Here’s hoping whatever has caused the problem can be identified and fixed quickly.

    Fear not though Scotland’s transport journalist of the year has just tweeted that he’s awaiting “public confirmation”.

    Someone isolated something that shouldn't have been, quite how that was missed is a wake up call.

    Very interesting and quite worrying. Nothing quite seems to add up properly in my mind - for instance, the source in the Scotsman says "There was no immediate safety risk" - but I'm struggling to think of an occurrence where calling the signaller to ask for a clear route through a station in an emergency would involve no immediate safety risk. Were the brakes on the coaches isolated from the locomotive so the driver effectively only had locomotive brakes available? Should this have been spotted in a running brake test or perhaps could it be possible that (if the gradient were against the train, for instance) the difference might not be noticed? Or could this have been a failure that occurred after Carstairs that happens to be unrelated to the uncoupling? I'm certainly waiting for the RAIB report with interest.

    I'm mystified how, if it had a brake issue, that the problem didn't become obvious on the long descent which starts not long after Carstairs - many miles at 1:100, isn't it?

    Shunter left brakes isolated on the rake. This is not speculation. Happy to be told it is, if it makes anybody feel better. :)

    I've mentioned this before but ages ago a Deltic on an ECML express was coupled without the isolating cocks on the brake pipes being opened. The situation was saved by an alert dining car attendent noticing they had rattled through a planned stop at staggering speed and pulling the communication cord. There is nothing new under the sun, but I'd assumed a RBT was de rigeur. It is now, as they say in footy.

    Sorry, can you expand "RBT" please? Not one I'm familiar with. Unless you mean Routine Brake Test?

    So, if the explanation given is correct, are we saying that this could've happened a year ago with a mk3 set? It's just an unfortunate coincidence that the incident occurred with mk5s?

    Not being funny, but couldn't the driver have communicated with the guard and asked him/her to activate braking via the communication cord (or whatever they call it nowadays) to stop the train? Rather this than have the train carry on and overshoot the station. Just thinking what if something like a landslip had occurred in its path, or a trespasser was on the railway - not being able to stop timely could have been a disaster waiting to happen.

    The locomotive brake was used to bring the train to a halt.

    That's almost Campbellesque spin. Several hundred tons was unable to stop because of what seems like a human error (can and does happen) and a system that allowed it to happen and hadn't designed the risk out via software or systems. How can that not be a major, major safety issue ? Imagine if the Orange Army was working in the four foot ?

    The brakes were not faulty. They had been disabled and couldn't work. That is not a footnote in a safety briefing. It's a proper WTAF moment..... (so bad it needs a four letter acronym, not a TLA...).

    The "orange army" should and do have safe system of work that does not rely on anyone but themselves.
