I've seen a few messages that relate to specific route numbers. For example, on the Aston sim, I've got a train waiting at Lichfield Trent Valley platform 3 with the ARS status "Route not available: RAN162AM". In this case, I think I know the route they're waiting for, but am I supposed to be able to understand/find anything from that route number? The train is at signal AN162, so I guess that's the middle part of the route number and the starting point of the route they're waiting for, but I can't see how the rest of it tells me where they want the route to go to?

It's fairly simple. Each bit of the route number means something, so in your example we have: R - route. As opposed to S for Signal or P for Point. AN162 - the Signal box code (AN for Aston) and signal number in question. A - Routes are coded left to right, so A is the left-most route, B is next, then C and so on. M - main aspect route.

The last character can also be W, or S as well for Warner (reduced overlap) and Shunt class routes. There are also a couple of other less common ones too. The signal box prefix is not always shown in this context either. Log in to reply The following user said thank you: p72endragon |

And, just to confuse everybody, there is more than one system: 1. Routes are numbered rather than lettered, and the straight route comes first, so R123(1M) could be the straight on, while R123(2M) could be the left route. (Scottish) 2. Route letter and class can be swapped around, so instead of R123AM you have R123MA. (LNE) 3. If there is only one route, or only one class, then the letters could be dropped entirely (R123, R123A, R123M). 4. If there is more than one route of the same class between the same pair of signals then they could be infixed -1 for the first preference, -2 for the second (R123A-1M, R123A-2M) - or just given another letter (R123A and R123B go to the same signal). 5. Brackets aren't used in SimSig but in real life it could be R123(A)M, R123(AM), or R123A(M). I doubt the above covers everything.
