What do the letters ROL at each end of the station mean or indicate? I have seen them on another sim - Feltham I think.

It's stands for Restictive OverLap

Railway Group Standard GK/RT0064
Issue One
Date December 2000

Provision of Overlaps, Flank Protection and Trapping

3 Definitions

Overlap
The distance beyond a stop signal which must be clear, and where necessary locked, before the stop signal preceding the signal in question can display a proceed aspect:

a) Full Overlap - An overlap of at least 180 metres (or 400 metres in the case of a semaphore signal where the preceding caution signal is also a semaphore type).

b) Reduced Overlap - An overlap that is shorter than the minimum permitted length of a full overlap, where the permitted approach speed is below a specified level which still allows an unrestricted approach to a signal at danger (ie approach control is not necessary).

c) Restricted Overlap - An overlap that is shorter than the minimum permitted length of a full overlap, which is available only when the preceding signal is subject to approach control by selection of a warning class route.
