RMweb Premium mezzoman253 Posted December 10, 2009 RMweb Premium Share Posted December 10, 2009 Hi all, At the risk of hijacking this thread, I'm about to embark on signalling my layout and this has been a great help. Like the OP I'm a novice went it comes to signalling, but following this has helped a lot. I've a very similar set up, but with the two through roads as a terminus. Additionally there is a set of sidings to off the upper road and to the right of the headshunt. A long thin layout, with the sidings hiding the fiddle yard. Would any additional signalling or alterations be need to accomodate this difference please? MTIA Rob Link to comment Share on other sites More sharing options...
David Rickard Posted December 10, 2009 Author Share Posted December 10, 2009 Well these pages were useful: http://en.wikipedia.org/wiki/UK_railway_signalling http://en.wikipedia.org/wiki/British_railway_signals When I looked on Wikipedia the other day I didn't find much. Then some Googling got me there. Ho hum! I need to find somewhere to get these signals from now. Anybody have any recommendations? I'm in N-Gauge. Massive thanks to all involved in helping though. It's been really very useful! Link to comment Share on other sites More sharing options...
RMweb Premium mezzoman253 Posted December 10, 2009 RMweb Premium Share Posted December 10, 2009 Hi Dave, Thanks for those Wikipedia links, had a quick look at the first one and seems very helpful. Hopefully a plan of the layout will appear if I've done it correctly. Rob Link to comment Share on other sites More sharing options...
David Rickard Posted December 10, 2009 Author Share Posted December 10, 2009 Oh wow! I bet that'll need a few signals! Link to comment Share on other sites More sharing options...
Glorious NSE Posted December 10, 2009 Share Posted December 10, 2009 Would any additional signalling or alterations be need to accomodate this difference please? Beast made a comment earlier about different ways of handling the signal with two feathers, one of which would be a theatre box (box that lights up giving a platform number) - the two are somewhat interchangeable but one criteria is the theatre box can only be used where the approach is a fairly low speed, not usually a problem at a terminus but possibly a problem at a through station. You can also do a version with feathers and a theatre box, but that's a bit overcomplicated for either of these scenarios I think, you might need that if you have more than three divergences in one direction though. That same signal also wouldn't need a green aspect either if it was approaching a terminus (just red/yellow lights), you can't go past the next signal as it's the red light on the bufferstops! At some point in the past and in some area's this might have been red/green, but red/yellow has been standard in that situation for a good while now. I think it would be less likely you would have a feather on the platform road as well if it was a terminus as you won't approach it "wrong line" at speed.

Glorious NSE Posted December 10, 2009 Share Posted December 10, 2009 Actually looking at your plan that signal with the feathers/theatre box would be off-scene anyhow so don't worry about it! Add a ground signal to come out of the small yard (CE and Warehouse) towards the station or depot and you're sorted I think. Link to comment Share on other sites More sharing options...
RMweb Premium mezzoman253 Posted December 10, 2009 RMweb Premium Share Posted December 10, 2009 Hi Martyn, Thanks for your comments. I'll have to read the Wikipedia pages and decide what to do next. Rob Link to comment Share on other sites More sharing options...

Normally is the key word Martyn - Lancaster has a theatre on the Up Main "home" and the line speed is 75mph iirc. Link to comment Share on other sites More sharing options...

hairyhandedfool Posted December 11, 2009 Share Posted December 11, 2009 Some people may find these links helpful, and as they are already easy to find on the net and therefore in the public domain there is no comeback for posting the links!

RMweb Gold The Stationmaster Posted December 12, 2009 RMweb Gold Share Posted December 12, 2009 Hurrah! Well I think I'm actually getting it. I might keep the left hand feather. The Aylesbury station has one, and I'm loosely (very loosely) basing it on that. It was all re-signalled in the 90s, so I'm guessing they were doing it then, either that or they've added it in recent years. So here's a 'final' version. I think it looks pretty spiffy The provision of JIs for crossover movements where there was no 'straight ahead' route resulted from a change to the Signalling Principles in 1984 although there were then (and still are) some circumstances where the JI is not required for such routes (relating to line speed on aprproach etc).

That would make sense, I believe there are ones in that scenario at Newton Abbot which was circa 1985. Link to comment Share on other sites More sharing options...

Same at Reading on the DRL - been there since 1965 (signal renewed a few years back with both JIs and a theatre). Link to comment Share on other sites More sharing options...
