UKTrainSim ("UKTS") is a web site that acts as a kind of virtual club-house. People who enjoy Train Simulation gather here and share their work, knowledge and experience with others. It might be a new loco someone has built, or a route, or it could be sharing some knowledge about real world train operations. It could simply be recalling something memorable you saw on the line out of your bedroom window when you were a kid.
This pack has been checked and should work with Railworks 3 / Train Simulator 2012.
