Hi all
Been continuing to play the 2009 default TT for Wembley mainline and have come across my next issue.
6L51 has been parked up on the Up South West Sidings awaiting 0L51 to leave Ferrous Fragmenters. I now have 0L51 held at 621, however when calling 621 onto either 743 or it accompanying white triangle I get an error of 'Subroute locked in opposite direction'
There is no route set from 628 to 626 (626 being the signal at which 6L51 has been left at awaiting a loco since 0700 (current time 0809))
Save Game attached of the issue.

I had the same issue - I did wonder if it should go in the 'SW Thru Sdg' but haven't had a second run to test my theory yet!
There's the right way, the wrong way and the railway.

I've just run the scenario again and can confirm that when routing 6L49 into either the SW Thru SDG, or the Down South West Sidings, you are able to call onto 6L51 after 6L49 has departed. That being said i have found another bug which i've reported separately.

I wonder if the Up sidings is meant to behave like the others or if it is correct in its operation. One for Geoff to confirm. However, Geoff is it possible to allow the location Willesden South West SDG to have some platform codes for timetabling to either the Up, Down or Thru Sidings

Running the Olympic TT, I eventually managed to get 0L51 to run in in front of 6L51, after a lot of setting and cancelling routes, and the train list shows that 6L51 is in front of 0L51 and vice versa. The problem is that they won't join.Is there a way to force them to join?

First thing to check is that each part of the join thinks it is at the correct location. F2 - right click on the train or loco - edit TT and make sure that the joining location is picked out in bold type. If not, highlight the location, click on the Set Current/Next button and OK everything. This will only work if the train/loco are also physically at the correct location (not short of the actual location because the other part of the join is overhanging the section).

If that doesn't work, post back and see if any other ideas are presented.

It looks like they are in different locations - 0L51 is reported at Mitre Bridge Jn and 6L51 at Willesden SW sidings. It's a while since I've been on NLL so I can't picture precisely where they are and what to do, but the answer is probably for them both to shunt one way or the other to whichever location the join is specified to take place at.

e.g. if the join should be at Mitre Bridge Jn then reverse direction of 0L51 and let it run forward in the up direction, 6L51 should then follow and hopefully step its location up to Mitre Bridge Jn. When it does, then you can reverse the direction of 0L51 again so that it is facing down. The two should then meet and, being in the same sim location, join. Some shunt forward might also help them get together when they are in the right place.

Now that SimSig keeps track of powered and unpowered sections you can't automatically do that and expect the unpowered section to follow which can make things a bit problematical.

Brings to mind one of the first driver training simulators on the WCML when people were a lot less used to things like Ctrl-Alt-Del or re-cycling the power. I read once that one of the trainees managed to stop his electrically hauled train in a neutral section and everything ground to a halt. The problem was finally resolved when the instructor remembered that the software could change the gradient on which the train was running and tilted to full downhill until the train free-wheeled out of the neutral section.

Good point. That won't be a problem if 6L51 has not yet detached its loco, or if the timetable doesn't use the new DEF/DER to identify loco detaches, but otherwise.....I'm not sure where the tilt option is on Simsig, and with the brakes on it wouldn't help anyway!

Reminds me of the time I'd had a Mexican stand-off on Carlisle, tried to move the coaching stock, thinking that SimSig wouldn't know the difference, imagine my annoyance when it complained of no engine!

All seems correct. As you can see from the train list, 0L51 thinks that 6L51 is in front of it, and vice versa. Can't shunt 0L51 forward because of the train in front.

I presume that the joining location in the TT(s) is Willesden SWS as that is where the unpowered section is sitting. If the situation is still as per your original report, the join cannot take place because 0L51 does not yet think it has arrived at Willesden SWS - F2 shows its last recorded location as Mitre Bridge Jn. This is as per the postings Goochy B and I have already made.

If you have moved things on since the original report, can you please confirm from F2 the reported locations of 0L51 and 6L51. Unless the sim thinks that they are both at the joining location specified in the TT, you will not be able to complete the join.

Although the present/last position for 0L51 is Mitre Bridge Jn, it won't move forward because it says that 6L51 is in front. I have tried marking next position on the TT, but nothing happens.

have you tried reverse direction on 6L51 to shift it along to make room for the loco? As Postal notes, that won't work if the sim regards it as a loco-less train.

If 6L51 won't move then the only other option is probably to adjust the length of 6L51 to make it shorter, although I'm not sure which end the sim would take the length off - reverse direction might make a difference in that context.

As an alternative, have you a save from slightly earlier so you can try and recreate the move without getting yourself into this pickle? You won't be able to make anything change in the save you have posted unless you adjust the length of 6L51 as suggested by GoochyB so that 0L51 can advance into the track circuit making the sim think it has arrived at SWS.

Yes. That much I know, but it means going back to 06:40, before 6L49, from which 6L51 was detached, entered the area. But I want to know why it happens or what I am doing wrong.

I don't think anyone will be able to answer that unless they can actually see what moves you made in the lead up to the problem. Have you thought about setting the autosave so that you have regular saves on your hard disk in case you need to backtrack. You can always delete the unwanted saves later on.

I am afraid that the signalling in "South West" is working as per the prototype, there is no attaching facility provided on either Down or Up South West. Prior to the Xmas 2000 re-signalling, we had the facility at Willesden PSB but afterwards at Wembley we had no facility, not that train planning would take any notice and continued to time loco changes on charters and that is another story.

I was involved in preparing the method of working for 6L49/51 and the agreed and published method of working was for 6L49 to arrive via Acton Wells and run onto the Up & Down Thro Siding. The signals were cleared towards Mitre Bridge Neck and the train drew forward until the rear of the train was in clear on the Up & Down Thro Siding. The train comprised of 14 bogie box wagons and was split between 7 & 8, with the 1st portion running as 6L49 to Ferrous Fragmentisers. The loco 0L51 returned to the through siding and collected the 2nd portion now as 6L51 and again shunted to the sidings. Inside Ferrous Fragmentisers are 2 roads each accommodating a loco and 7 wagons, the length of each portion required the Neck at Mitre Bridge as it would not get in clear in rear of 1185 signal. The loco off this would usually rush off back to Hither Green as the crew were hurrying to book off. The afternoon job was light engine via Kensington and ran direct to the sidings and required one shunt out and back to make up the train which would then depart via Kensington.

One small item to remember is don't clear 1185 to Ferrous Fragmentisers without the mobile ground staff present as there is an open crossing just inside 1182 signal!

In the Olympic timetable updated January 2015, 6L49 does not have a loco joining it. However, 6L49 appears to have left part of its train on the Up South West Sidings at TWLC. As signals will clear in this section, a slight adjustment is needed to fix the TC.
Have attached a save.

In the 2012 timetable, the only way I could get 0L51 to realise that it was at the SW Sidings was to remove 6L51. Shortening 6L51 didn't work, nor running 0L51 around and trying to attach it to the Acton end of the train.

0L51 still thought it was at Mitre Bridge Jn the whole time, until 6L51 was removed. Presumably there is a trigger point somewhere in the up and down SW Sidings that 0L51 couldn't get to?

Haven't tried putting the whole train into the Thru Siding though. Has anyone had any success using the Thru siding?
