Great description and easy to understand. I’d like to clarify why the distant cannot be cleared if the stop signals are not also cleared. The distant is only interlocked with the home signal and therefore can only be OFF if the home signal is OFF. The home signal (and any associated stop signals between the home and starter/section) should only be OFF if the driver will not see an irregular sequence, i.e. green followed by red. If the train is not accepted by the box in advance and the starter/section signal is ON, you have to clear each stop signal when the train is at or nearly at a stand at each stop signal in turn, until it is stopped at the advanced starter/section signal. This is known as regulating the train, commonly referred to as stepping down. Also be wary of saying a distant signal shows danger, by definition it can only show caution or proceed aspects, it will never show red/danger.
Very well presented. For a basic introduction to signalling, it covered a lot of very salient points. As for interlocking, it isn't really that difficult if you are able to think logically. I have a limited amount of interlocking on my own layout that basically prevents a signal being cleared for a route that hasn't been set correctly. The only reason I haven't gone for full interlocking is that there isn't enough room in my control panel for the relay boards that would be required.
Hi. Yarslow is designed as a one-man operation layout so I decided to steer clear of interlocking. Each of the 14 sections on the layout can only be switched to one controller which, in theory, cuts down potential collisions but it is still very possible! Guess how I know that.....................
Brilliant, thanks! Exactly the sort of thing I was hoping for when you asked for suggestions about bite size bits a few weeks ago... thanks again and keep up the excellent work if you are able.
Hi William. Thanks for your comment. The ground signals come from West Hill Wagon Works as a 3D print. A bit fiddly to make but, as you say, very nice :-)
thank you my late f ather was a train driver on foggey day in the late 60s he was running light engine 03 shunterbetween south gosforth and jesmond went past a redlight derailed at the catchpoints gateshead breakdown crane called outslapped wriast for that one
Great stuff just what I had hoped for. One small point - I think in the example used running round the train would be unlikely. The train would just leave the guards van on the main line (clear of the home signal) and reverse to drop-off/pick-up from the siding. Or perhaps to reverse the whole train into the siding so it could be overtaken by a faster train. One question - would the ground signal at the end of the siding provide enough authority to restart a train that had been refuged in the siding or would another starter signal at the end of the siding be needed? Thanks a lot Jon
Hi Jon. You may be right about the shunting - I was just using it as an example. The ground signal is not authority to start the train, only access the running line. The train would have to pass the starter and adv starter to access the next section anyway. In a refuge siding, a starter could be used to authorise departure, probably up to a advanced starter (the limit of shunt and perhaps the point from which the train reversed into refuge). The difficult thing about signalling is that the rules were strict - "Thou shalt not..." but the many and varied track layouts created many different signalling solutions. Best to look at examples of your chosen railway to get a good idea of what they woud have done.
Nice. The more I look at this, the more I can see that most layouts would extremely rarely need to include a distant signal, unless they're modelling "the middle of nowhere" or at least the middle of a block, with any home signal off scene from the modeled distant. However, there is possibly more option to have a combined home/starter and distant post, where the next station or block are about 1/4 mile down the line. Is there a chance you might introduce the next level, where we look at shunt signals and shunt limits? And why they might be included?
Hi Neil I feel a "part 2" is going to be needed to cover those things I didn't here. The risk was the vid running to 30-40 minutes - hardly a Bite Size!!
That was fun, well done,
Signaling - never enough, and always something learned, thanks again
Glad you enjoyed it
Another piece of quality content from one of my favourite model railway RUclipsrs. I'm proud to have known you and your channel in this life, man.
Cool, thanks!
Thank you! So very well and concisely explained!
Glad you enjoyed it!

Thanks for this. Always happy to learn or get clarification from people who know more than I do.
@@yarslowmodelrailway1 it’s an easy topic to ignore but it can really enhance operational.
Hi, your bite size videos are all very helpful to guys like me who are just starting to build there layout .
Thanks for sharing 👍.
Regards Frank
Cheers Frank. The irony of the signalling video is that I don't have any yet :-)
Thanks. Never seen an understandable explanation of advanced starters before. Keep 'em coming.
Glad it helped!

Excellent summary. Thank you.

a verey interesting topic i like the look of thouse double disc ground signals who make those

At least he didn't hit anything and hurt himself!!

@@yarslowmodelrailway1 The split makes sense, you cover the absolute basics here, which is sufficient.
Thank you.
No worries!
