GeoffM in post 118920 said:Late Turn in post 118915 said:Slightly off topic but related to overlaps. Apparently there was an incident at Pitlochry yesterday where new signalling has been installed with the signal half way down the platforms to allow for the overlap to be within the passing loop. This apparently is to permit trains to enter the station from both directions at the same time. Unfortunately whom ever thought this up did not appear to consider what would happen if two long-ish trains were passing (not entirely sure what the lengths were in this case) such that they fitted the loop but not with the signal placed in the middle of the platform.Derby (certainly prior to last year’s resignalling) had a formal policy to encourage routes out of the station to be set prior to the arrival of through trains where possible, even those with crew changes, which I understand was to let drivers approach the normal stopping point a little more confidently.That makes sense - no overlaps, so the train would have a route instead.

One train (1H89) was 735ft. Not sure how long the other was (5Z73) Paul You have to get a red before you can get any other colour Last edited: 13/06/2019 at 23:36 by headshot119 Reason: None given Log in to reply |

Of course it was considered, the scheme plan was signed off by the Operations function and made it through several MSRPs long before any work began on the ground. The Operational Planning Rules were updated to reflect the shortened standage available - Monday’s issue was down to a NR Train Planning error. The situation at Pitlochry is no different from any other loop on a single line when it comes to overlength trains... two trains can’t cross if they’re both too long for the loop, it’s as simple as that.

Hardly something you’re going to launch into on the Highland Main Line with a loaded passenger train though, is it. And that’s before you consider that the Mk5 sleeper coach couplings are incompatible with standard drawgear.

So out of interest, how was the situation resolved? Did one of them have to reverse back to Blair Atholl or Perth (assuming the length problem would be the same at Dunkeld)?

The issue is not with the length of the loops as such, it's that the signals are in the middle of the platforms. Peter

Peter Bennet in post 118958 said:The issue is not with the length of the loops as such, it's that the signals are in the middle of the platforms.The position of the signals reduces the standage available though, thereby effectively shortening the loop in each direction. There are also problems with the newly converted (to MSL) pedestrian level crossings south of the station, Dundarach and Prospect Place, which time out and give a failure indication whenever an overlength train stands in the station. I do concur that this is definitely not the optimal solution we’d ideally choose as operators but it meets the criteria specifed in the project brief which was to increase capacity and reduce journey times by allowing simultaneous acceptance from either end. We’re a long way from TRTS indications now! Last edited: 13/06/2019 at 23:38 by headshot119 Reason: None given Log in to reply |

Peter Bennet in post 118958 said:Yeah one train was talked passed to allow the other to move. The new layout at PIT is a complete mind **** for train crew and passengers. Though the log was an interesting read for this particular event. The whole HML needs a TT reshuffle, in some way that most trains would pass South of Stanley Jn and between Blair and Dalwhinnie. And the sooner they get on with doubling the track from Kingussie the better... but good luck with that.

Hap in post 118963 said:That pattern is how it used to be, and I believe the new hourly clockface timetable (Dec 2019 ?) has those, but also has crossings at Pitlochry and at Aviemore hourly, hence the work done to allow simultaneous arrivals. The other crossing is presumably on the double north of Culloden - unless restoring double to Daviot is planned. Bill Log in to reply |
