Dan,
There are some assets that have, what we call here in the US and Canada, is cab signalling. This where the signal indications are shown in the cab as well as on the signal post, and sometimes ahead of time. This gives the engineer/train driver a heads up on the signal indication before he gets there.
The MN content, also found in TS2009 and up, and originally from TC 1&2, has scripts for this and the signal indications change.
If you can get a hold of TC1&2, you can see how this works.
