TT rules query 21/02/2013 at 12:12 #41666

Hi all,

On the new Westbury TT I am working on I have a train, ID'ing as 5O33, that works to Yeovil Junction, then returns as 5O34:

5O33 1400 Salisbury TRSMD - Yeovil Junction, arr. 1542
5O34 1609 Yeovil Junction - Salisbury TRSMD, arr. 1824

Both trains operate via. Westbury where they reverse. Three queries therefore:

1. I currently have 5O33 set to run 50% of the time as it runs only as required. According to OTT, however, the train runs every weekday between 10th December 2012 and 06th December 2013. In the interests of accuracy on the TT being created, does that mean that the train would run every day without fail?

2. Bearing in mind that Yeovil Junction - which is where 5O33 terminates and 5O34 starts - is not on the Westbury map, what is the best rule to use to prevent 5O34 entering unless 5O33 runs?

3. Should I use the departure time from Yeovil Junction as the entry time onto the Westbury area? The entry point is "Up Wessex (Yeovil PM)".

Cheers,
Dave

does the train run as required (might be listed as "Q"or is it seasonal, ie compulsory between two dates?

"Train 2 must not enter until X mins after train 1 has exited the area". this will both ensure the second train runs only if the 1st does, and will also prevent it entering before the 1st has left

the Entry point is Yeovil pen mill. if a time is provided in the WTT for pen mill, use that. if not then make a reasonable guess based on similar trains timings.

Hi JC,

Thanks for that. In reply:

1. The train runs as required and is indeed listed as "Q".

2. Thanks for that advice on the rule: I will use that.

3. Interesting. I once tried out a diverted 1A40 to enter at Pen Mill according to the time there. However although the train entered on time at the point in question it then left Yeovil PM 2 minutes late! I have set it to use the Yeovil Junction departure time for a trial and will see what happens.

As it's a Q path but timetabled every weekday, it means it could run every weekday if required but does not necessarily do so. The path is there to be used if required.

Can't recall seeing it in the day, though there used to be one in the day time using a Class 170 (which they don't have anymore). No one on Gen groups have reported it apart from 2007, with the Class 121 (which SWT also don't have anymore).

I see it's timed for a 159, it might run now and again anyway.

As for the entry point, it seems to be before Yeovil PM itself, and I tend to have a train enter 5 minutes before the booked arrival at Pen Mill, never has trouble with time keeping.

Thanks guys. One more thing though.

I have spotted that I have three trains scheduled to use P3 at Westbury at the same time:

- 1x passenger train terminating here at 1657: departs again at 1742 on next service.
- unID 1616 Merehead Quarry - Acton Terminal Complex, arr. 1705 dep. 1729
- 5O34 1609 Yeovil Jcn - Salisbury TRSMD, arr. 1733 dep. 1748

I have it in mind to put the unID freight onto the UR line which gets rid of that problem but how long is Platform 3 at Westbury? Would it take a Class 165 / 166 (69m) and the Class 159 on 5O34 at the same time or will I have to reroute one of them? P1 & P2 are taken while that passenger train is in P3.

Advice welcome.

Cheers,
Dave

Platfrom 3 is 197 meters so long enough to accomodate both of the DMUs

From the WIKI manual:

Westbury P1 224m/245y P2 203m/222y P3 197m/215y

Edit: Also from the manual:-
"Permissive working is banned for passenger trains unless they are booked to join another train."

Edit: 5O34 to reverse on UR after freight departs, or Westbury East (rev)/Trowbridge Sdgs?

I can only help one person a day. Today's not your day. Tomorrow doesn't look too good either.

Fine so 5O34 goes elsewhere but I will have to think where to stick it. May reroute it to DR if that is free. Thanks guys.

Where as the actual box instruction reads:

"Platform1, 2,3: Authorised for timetabled attaching/ detaching movements and platform sharing*. Movements that are non-timetabled must be stopped and the Drivers advised of the circumstances at the signals listed.

*For the purposes of this instruction, the term "timetabled attaching/detaching movements and platform sharing" means those trains shown in the Working Timetable to make these moves."

"Passengers for New Lane, should be seated in the rear coach of the train " - Opinions are my own and not those of my employer

There are ad hoc (untimetabled) shunting moves going on at Westbury all day so there is the possibility that one unit goes into the sidings while another comes out.

Indeed Geoff, I'm lead to believe your passenger train Dave in Platform 3 is 99% likely to perform an untimed shunt to Westbury East Reverse using the Down Trowbridge Siding.

Most trains with long layovers that need to move out the way, either use the Down Trowbridge Siding or park up in the DMU sidings.

I have given it a layover in the Down Trowbridge Siding. There are a couple of others with similar layovers too.

Whilst I was at Westbury last June , in the afternoon a class 150/1 DMU moved from P3 and reversed into the old Engine Sidings where it remained for over an hour before moving back into the station.
