SimSig Edinburgh

ARS Coding

For the purposes of writing and understanding timetables the following information is important. See also ARS timetable writing for the basic ARS timetable conventions.

In this sim, as a rule, trains running normally will have the same codes in both directions and will be in the format xL where x is a variable depending on the line being referred to, e.g. FL is Fife Line Up and Down. Ux and Dx are used where a train is running ‘wrong-line’ on the relevant line. E.g. UF means train travelling in the Down direction on the Up Fife line.

DPL/UPL, and DGL/UGL are used for the passenger/goods loop respectively, in the majority of cases this particular code will be used in the Platform box to tell the train to diverge from the xL which will remain the appropriate code for the Path and Line.

In specific instances special codes will be required and their use will be explained.
