Were any Caledonian Sleeper services originally scheduled for last night? Did they get binned? :?:
According to Railcam the Euston to Inverness sleeper ran, but with only a half train (7 vehicles) due to set problems at Euston. It ran via Lockerbie, so presumably there was single line working overnight.
Southbound sleeper as per note above.

Not going too well at Lockerbie.

Same incident.
On the one hand I'm glad it's not another failure, Avanti seem to have been having a spate of poor luck at the moment. On the other hand it's unfortunate it's not proving easy to shift the stricken unit.

(Keep seeing Voyagers going down the GSW and I wondered if the incident was a new one or not.)

Normal working has been resumed, Open Train Times is showing the Up Postal as having passed Carstairs.

Hopefully passengers on the 1540 will just be in time to transfer to the 1640 at Carlisle...
A friend of mine who works in Lockerbie managed to get to the station in time to make a short video of 390 138 arriving - very slowly on the wheel skate - in the Up Loop, plus some close up photos of the damaged wheelset on its skate. He spoke with some of the engineers on site and they told him that the unit would be moved overnight tonight at 3 mph back to Glasgow (Polmadie?), where the affected car, 69138, would be detached and sent by road to Manchester (Longsight?) for repairs.

VSTP timings now shown on RTT for 5S19, 23 30 Lockerbie to Carstairs loco-hauled ECS tonight, reaching Carstairs at 05 21. Shown as diesel locomotive-hauled: maximum speed 45 mph. With those timings and with that wheelskate, I suspect that it will be going much slower than that!

At around 80 miles, it would take best part of 24 hrs at 3mph to get there, longmoor at 3mph would seem more likely or a higher speed to Polmadie, 10 mph probably be enough not to impact services in the morning


Edit just seen your next post, answers that one then!

Lockerbie to Carstairs is just under 50 miles, It's been given 6hrs to get there. Average speed of 12mph or so. Given wheelskate is 20mph on plain line and 3mph over pointwork, the bigger issue will be how often it gets looped for traffic to pass.

Single line working (or simbids where fitted) or diversion via ECML. There is very little traffic around at that time anyway so there won't be much impact on services until approaching the Glasgow suburbs

SIMBIDS not fitted between Carlisle and Carstairs, only emergency trailing & facing crossovers requiring Single line working with pilotman (which is what happened last night). Diversion via ECML is not feasible as Container traffic would have an awfully long way round to get to Newcastle. True there's only 1 passenger train, but there's plenty of freight that takes advantage of the relatively quiet railway on a weekday night. Not the least because it's been waiting for 24 hours whilst Lockerbie was shut to recover the stricken pendo.

Simplified bidirectional signalling
Simplified in that it doesn't provide the same level of protection/flexibility as fully controlled bidirectional signalling does. The idea is to allow more capacity than single-line working would, without the expense of full-blown bidirectional signalling. I believe that the main thing that is omitted is that there's no AWS in the wrong direction.

IIRC, quite a lot of it was installed in the 1980s (90s?) but it's not allowed now.

Edit - It was discussed in this thread: https://www.railforums.co.uk/threads/simplified-bi-di.158849/

Thank you as ever - in what way is it 'less safe' or sub-standard?

SIMBIDS is used on the ECML between Northallerton and Berwick but not beyond towards Edinburgh which surprised me. It is useful in keeping the job going but doesn’t provide much capacity so often TPE services are caped with priority given to LNER and XC services. As @najaB rightfully says above there isn’t any AWS provided when running in SIMBIDS and speed is limited to 50mph.

Looks like it’s gonna be a slow journey north tonight then, 20mph on plain line is at least doable but having to slow to 5mph and occupy every loop en route is going to take its toll. Beattock will also put a lot of demand on the locos traction motors trying to maintain that low speed while climbing the gradient. A very challenging night for the driver rostered to work it

SIMBIDS is installed on the ECML in Scotland between Grantshouse and Innerwick too.

The rescue driver has tweeted its 15 mph and stop every 8 miles for fitter exam

Believe the move to carstairs was due to start at 2330. As of yet still not on the way.
