Was pleasantly surprised to find my Trainmaster 4.0 copy (that I forgot I owned) loaded and RAN on my Window7 computer! It has been my experience usually older stuff won't play nice in newer computer sandboxes.
Googling Trainmaster shows it is up to version 4.3 now and owned by RailDriver.
Without tying up alot of thread as this is OGR about model trains and not simulators, but just wondered what is/was better about 4.3 since it says upgraded in 2001? Better graphics, works with more video cards, better sounds, more trains and tracks? Worth upgrading if I wanted to?
