Not sure if this has ever been brought up but I always thought signal 121 at Haresfield UGL had a bug because it doesn't display any aspect until a route is set onto it from signal 21. I passed it the other day on the train and it is correct, the signal was completely unlit! So does anyone know what the reason is for this? Seems a bit unusual. Log in to reply |

I have not checked on the sim, but from what you have said and from what I remember, it is an approach lit signal It is also described in this page about the Gloucester sim (by the way I am getting a little bit confused about the structure of the documentation of the wiki. What is the difference between [[usertrack:mans:gloucester]] and [[usertrack:sims:gloucester]] ?) Log in to reply |

Interesting, thanks. Why do we not see it more often?

SouthernMafia said:Interesting, thanks. Why do we not see it more often?I think that is because they may be rarely used now, possibly. One of the routes in play in BVE4 has a signal passed on a loop that is unlit, I reported this as a bug however I was told that it was unlit so as not to confuse the driver (i.e: Me) and make me think it was a signal for me, instead of it being for the loop line next to/alongside me. It's understandable if they are used, after all driving along in the dark with little lighting ahead of you (unless your train headlights are powerful enough) if you saw a red light to your left hand side you may easily confuse it with a signal not meant for you. I think the developers have done very well in simulating this, it works perfectly

The Wiki does need a good tidy-up - we planned to do some yesterday but there was too much else to do!

Approach lighting is provided for in the Standard Signalling Principles (or whatever they're called these days). Unfortunately my father's papers are in the loft where I can't get at them easily so I can't quote them verbatim (and they're rather old anyway, but I suspect the principle remains and it wouldn't surprise me if the wording is unchanged). It's not common but it is allowed/mandated (not sure which) in situations such as this where there's a signal for (often) a loop that could confuse a driver passing on the main (in this case it could appear as a red having passed better-than-yellow). I believe some of the loops on the Highland Line have it as well, where there's a bidirectional "main" line. IIRC it may also be provided where a signal beyond a facing junction is visible from the signal protecting the junction and there's a danger of read-through when the route is set the other way.
