Brighton TT Platform Conflicts 17/05/2016 at 02:29 #82445

34 posts 		I'm using the 04:45 Oct 2009 TT and I've run into a rather glaring platform conflict that if I let it run as the TT asks I'd be in a mess I suspect.

With a 4 car empty stock 5T01 waiting at the buffers for a slot to go into the depot I have a 12 car train 2A36 coming in to the same platform, meaning I'm looking at 4 cars too many for the platform length.

Schedule says 8 of the 12 are to immediately go into the depot leaving me with 8 cars still on the platform as two separate trains though in the order of their departures.

After this an 8 car train 1W86 is due to arrive and split into 2 more trains but then the next departure is the 4 remaining from 2A36 now called 2A23 which would be stuck behind 8 cars from the latest arrival.

The obvious thing for me to do at the moment I've paused the sim is just use the totally vacant Platform 7 that will remain so until all of the 12 arriving cars for 2A36 are scheduled to leave making my Platform 6 situation more rational.

Being new I have no idea if this is normal though. I have no idea if I should be diverting these trains to use my platforms better or if there's some other thing meant to be done. If I instead merely held 1W86 until 2A23 leaves which is only off by 1 minute it would also keep things kosher only I'm not sure that 2A36 can properly arrive at the platform if it can't use the full length.

Seems odd to me that the schedule would be sending a train here knowing the platform is partly full particularly with Platform 7 there totally vacant for an extended period. I include a picture for clarity. Its not that I can't solve this. I've already dealt with similar issues in the schedule, its just I want to know the correct way to do it. I also want to know if the TT is correct or if this is a scheduling oversight either on the part of the person who prepared it for SimSig or for real life.

Cheers



EDIT. Better picture.

34 posts 		That was very helpful, thank you.

Now I would love to have someone comment on what a real signaller would do. I assume my decision to use Platform 7 is correct so I just move on to asking if I shouild bother to change the timetable or do I just let it roll and let the train operators deal with it? Arrivals seem to work just fine but would new trains operate correctly from the wrong platform or should their TTs be changed before or after they form to make them leave properly?

The answer is "it depends". Here are some scenarios:

  • Small station, local signalbox, no impact on passengers: Signaller would probably just do it.

  • Large signalbox, no impact on passengers or plenty of notice, no train operators within shouting distance: Signaller might confer with shift manager or somebody appropriate.

  • Large station, train operators within shouting distance: Signaller would likely confer with train operators as to what they wanted.



And then many variations thereof.

Back when I were a lad...

(Titter ye not in the stalls there )

One of the things signalmen would often do when the new timetable was issued (hopefully a week or two before it came in!) was go through it and work out what would be going on. (I think in the bigger powerboxes, it would more likely be done in the Area Manager's Office, where an operating clerk had the job of preparing 'daily orders' for the box.) Certainly I used to do that at Marylebone (I was in the 1967 mechanical box BTW, not the present IECC). When I first went there I prepared a 'minute by minute' book - I redeployed a blank train register book and, using one line per minute and different colour pens for each platform (easy when there's only 4) recorded every move. Didn't take long for conflicts to show up. It was somewhat complicated by the amount of joining & splitting we did each side of the peaks, but even there it showed fairly readily where the issues were likely to arise.

What happened on the day was usually a different matter of course...

Just spent a lovely morning controlling trains on panel 6, with trains stabled all over the place due the lack of guards. But re-platforming trains is all part of the job and go be honest we don't use the WTT but use daily platform workings supplied to by southern for Brighton and simplifiers for Hove and Preston Park even though they have Brighton on them we use the daily workings instead.
