For your information, the Glasgow to Carlisle Route has been updated to v2.01, with a couple of activities for it too. All on UK Trainsim. There is a single download and split downloads available. It looks much better now.
Aswell as the line to Carlisle, it also includes the Cathcart Circle and spurs to some nearby places such as Newton. A map can be downloaded from UKTrainSim. v3 is well under way and is expected to be released around Christmas.
