Hi

I am trying to work out how to reverse my first train in Royston, it claims that it should reverse at signal lk246 and go into sheriffs but I cant work out how to do this.

Could someone point me in the right direction?

Thanks

Ben

Assuming it's train 6R02 in the 2003 TT, it reverses at signal K246, which is the shunt signal further to the right of LK246.

Signal the train to platform 2 (set route to K981), it should stop when the rear has passed K246. Then set the route from K246 to the grey triangle at the far end of Sheriiff's sidings.

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

thanks for that, solved my problem nicely. I had assumed I couldnt do that as I had platform 2 occupied at the time.

Hello

This is my first post and also my first attempt at using SimSig. As recommended I am using Royston to gain some experience of how SimSig works. I have run into a problem with the reversing of 6R02 into Sherriff's Siding. I pulled the freight into Platform 2 and set K246 into the siding and 6R02 routed correctly. However, I noticed that there was a duplicate 6R02 waiting at signal 975, which I could only remove from the sim by repeating the routing into Sherrif's Siding. Is this a known problem with Royston in paticular or any sim or is it something that I can correct myself? I am running Windows7.

Many thanks

Tim

Just tried and nothing went wrong.
Did you have a save and restart in between or anything other than a straight run through the timetable ?
Do you have any saved games before or after ?

Thanks for your reply. I have not done a straight run through the timetable but saving and exiting every so often. In fact I carried on after sorting out the double appearance of 6R02 without exiting and now the same duplicated train has happened to 3R17!

I think you have to remove and reinstall Royston if it continues to happen.

Save and continue should not cause double trains.

Yes, that is what I have decide to do as well. I was getting too many duplicated trains on the sim for it to function correctly. It was a though two parallel sims were running at the same time although I checked that that was not the case. I'll let you know what happens after I have reloaded. Thanks for confirming that save and continue does not cause double trains. Can you confirm that exiting the sim part way through the timetable and continuing at a later time is also OK? Regards Tim

Continuing at a later time cannot cause duplicate trains. You should only see them if you have clicked 'Duplicate train' in the timetable (F4).
There are no known bugs in Royston sim.

It would be useful to have a saved game with some of these duplicated trains in.

Maybe something like this? Were you pausing/unpausing the sim frequently?

Let him first try the reinstall, if that doesn't solve it we can discuss further about the reason.

Btw, 6R02 doesn't enter from a yard.

Well uninstalling the sim and reinstalling it seems to have fixed the problem. I have run the sim as far as 15:00hrs on the timetable and no reappearance of duplicate trains. Thanks very much for all the support. I am now scratching my head over how to route 6E55.

Later today, or maybe tomorrow, I'll look after 6E55 and make a screenshot of the correct route.

Thank you Albert. I may have solved it, but not necessarily the way it should have been done. I set S974 to red. 6E55 came to a stop just after S245. I then set the route S245/S977/S253 and and after a short interval 6E55 proceded onto the Down Loop and disappeared! It did leave a greyed out headcode by S976 - not sure why - which I cleared. The sim did not whinge at all so I assume all is OK.

This is my first SimSig sim (and not the last) so I apologise for asking all these questions.

Regards Tim

Yes, this is all OK. That headcode left is no problem - just right-click it and cancel. Then it'll disappear.

One other thought, as it seems Tim was getting two of every train, perhaps the timetable had been loaded twice ?

Timetable - open - merge with current would do this, and then persist with the saved game.

Bill_gensheet, have you read this? The problem was already solved.

Solved or not, it might be no bad idea to work out what went wrong for future reference and that's how I read Bill's remark

Yes it's one thing to resolve it and another to know why it went wrong in the first place- if for no other reason than to avoid it happening again or to fix a bug. I'd put my money on Bill's explanation.

Here are some screenshots which should help explain reversing at Royston.

Use Royston sim v2.201 with Perfect conditions and Royston 2003 timetable.

Reversing 6R02

To practise this one as per the default timetable, set the starting time at 07:13, since 3R52 appears at 07:14 and arrives at Royston 2 just ahead of 6R02. You will need to change its Train Descriptor to 1R52. It doesn't depart until 07:44.



Where are we going to put 6R02? Better find somewhere, and quickly. Parking it on the UP line is just going to hold up everyone else travelling in that direction. Unfortunately there doesn't appear to be a Down-facing signal between 975 and 981 where we can hold 6R02 to prevent it crashing into 1R52, so about all one can do is set a route between these two signals, cross one's fingers and pray. Here comes 6R02 now.



Well, well! 6R02 managed to stop, all by itself and without hitting 1R52 (though it looks like a near thing) as soon as its last wagon passed 246, a shunt signal not even facing Down. Who would have anticipated that?

Unless you happened to have the foresight to display the Train List (F2 key), you might not have known 6R02 would reverse here automatically on stopping. Notice that "Dir" has changed to Up. Don't you dare signal the driver to Reverse, or you will be sorry. Leave well enough alone.



Set a route from 246 to the grey arrowhead exit (circled) at Sherriff's siding.



Now 6R02 is departing at a stately pace. Just as well as there are two other trains waiting to use the same bit of track.




If you did act intuitively and signalled 6R02 to Reverse direction and then Shunt forward, you may end up in the mess below. You did remember to save the sim beforehand, didn't you?



In case you were wondering whether 1R52's presence is essential here, you could try starting the sim at 07:24, one minute before 6R02 arrives. This will be too late for 3R52, which won't be part of this scene. Set a route from 975 to 981 as before.



Contrary to what some of you might have expected, 6R02 still behaves according to its timetable and stops with its rear hard up against 246 instead of proceeding to 981. This knowledge should help you when next you play Royston at a higher difficulty level, with extra delays, etc. No matter what may or may not happen to other trains, 6R02 will still stop in the same position.



(to be continued)

Reversing 6E55

To practise this one, you might like to set the start time to 14:50 as 6E55 enters from Shepreth at 15:00 and you also want to display other traffic that happens to be around at this time.

I remember how my heart sank with dismay when I first saw "ROYSTON S K977/245 (REVE 15:10 15:16". What in blazes does this mean? Am I supposed to set a route from K977 to 245 or the other way round?



On looking at the diagram it all becomes clear. 977 seems the way to go since it's mentioned in the timetable and gets us halfway there. All we have to do is backtrack up the Down line until we reach the Limit of Shunt (LOS) signal kindly provided (which tells us the maximum distance permitted to shunt UP the DOWN line), reverse there and head off to the Down loop.

Since no other lines have a LOS signal, this confirms that we're on the right track, so to speak. Of course, there's that little annoying thingie (circled) which may have something to do with the LOS since it's abeam it, but since no one has bothered explaining its purpose, let's ignore it and get on with setting a route to 977 and then LK246 (the LOS signal).



Stuck! 6E55 is too long to fit here and all we've accomplished is to delay 1T62, approaching on the Down line. Back to the drawing board. How infuriating.



Well, that leaves us only one option - stay on the Up line until we find somewhere to park and reverse. Unfortunately, 976 and all signals beyond it are out of our control (grey). Hopefully 6E55 may break down or run out of fuel before it reaches Baldock.



How 'bout that? 6E55 not only stopped but reversed (Direction has changed to Down), without any help from us, once its rear end passed 245. So why mention 977 at all on the timetable?



To get from here to the Down Loop, the only route that can be set is between 245 and 253.



Yes, there it goes, with its own ghost train (circled) just as shedcode1e described in post #5 in this thread. More fun than an amusement park. The ghost soon vanishes of its own accord and our remaining task is to Cancel the 6E55 berth.



Summary
Wait for the train to stop at whatever signal is designated in its timetable, no matter how impossible this might seem. As a corollary, do not expect to be able to set a route to every signal mentioned in its timetable.

If the timetable says Reverse, expect the train to do this automatically (its driver should know to do this) and check its Direction on the Train List to ensure this happens. Likewise, normally there is no need to signal the driver to Reverse direction, Shunt forward, or Pass signal at danger unless nothing else works.

Don't expect the manual to spoon feed you. Treat each situation as a puzzle in which vital information may have been omitted.

Hope this helps.

Right then Maxand, some comments for you.

Firstly, your posts are useful on the whole, but some of the humour you've attempted does seem a bit rude in places. We need people to ask about things so we know they need explaining. Many of the developers/testers/wiki editors have been using SimSig for so long that we don't know what people new to SimSig do not know! We once found out by asking, and now we need to put this information together in the wiki/manuals so that everyone can see it.

For example:

maxand said:
Of course, there's that little annoying thingie (circled) which may have something to do with the LOS since it's abeam it, but since no one has bothered explaining its purpose, let's ignore it...

That is a set of points (named either catch or trap, I can't remember which) that are placed at the bottom of a hill to stop a train that is running away in the wrong direction from going all the way into Royston station. These points will de-rail this train and protect the station complex. They are set for movements whenever a route is set across them.

Also, regarding locations with multiple signals in them [eg: ROYSTON S K977/245 (Reverse)]

Using naming conventions across all sims, this is a reversing location to the south of Royston, and the numbers are the 2 alternative signals at which it is possible to do a reversing move. This means if one is in use or blocked, the other can be used. However, as you found out, 6E55 was too long to shunt behind 977 signal. There is obviously a limit to the length of a train that can fit between the LOS and 977. This information *should* be in the manual but may well need adding.

Some more information for you...

If a timetable has a time with a '/' in it, eg: 15/08, then this is a passing time. If it has a time with a ':' in it, then it stops there for one of many reasons, including station duties or reversing. So from 6E55's timetable you can tell it is booked to stop at Royston South Reverse (at 977 or 245 signal - but as you've found out it won't fit at 977) between 15:10 and 15:16, and therefore will not keep going with the player hoping that...
