I've noticed after careful observation that there are two left-hand arrows on WER 1053's route indicator; an arrow parallel to the ground and an arrow pointed upward at 45 degrees.
The parallel arrow always lights up when a route is set across the near trailing crossover to allow trains out of platform 1 at West Ruislip. Yet I've never seen the 45 degree left arrow light up.
I have a feeling that the second arrow is for the second trailing crossover betwen the running lines beyond the first trailing crossover, but I can't be certain. What's the second arrow for?

There are two routes from this signal, one that goes straight out, and another that uses the crossover just further up. *waits for PhilCentral for a technical answer*  |

That's basically it. AE32B at Edgware is similar.

Thanks MetApp and BAET.
Now for the really big question that XXXXXXXXPhil can answer: why is the second route never used by passenger trains?

AFAIK, It can be but just isn't used frequently

Now for the really big question that WoodLanePhil can answer: why is the second route never used by passenger trains? I will answer that one with my limited experience from working XXXX XXXX, although the computer doesnt use the move, I have on a number of occasions signalled a passenger train over the crossover. It is of course easier to use the first route. |

Not only easier but it improves the flexibility of the site, especially if there is a train just coming up to WER1070 (the home signal).
The computer probably can call the route but just has a hierarchy of routes with the first route as the preferred option.

Greetings
Yes WER 1053(1) is the " high speed" route out of West Ruislip, and 1053(2) Is much slower route over 1111/1112 crossover, this crossover has a history of unreliablity so although its avalible for use, we tend not to use it unless we have too, the crossover being there for the exit from 23rd essentially, and the second route from the platform is a bonus.
You cannot edit a trains trip to use the slower route, so you have to manually hold 1053(1) then when the time comes, ARS will automatically use the alternative 1053(2).
Hope that answers all that !!
