After a several year absence, I've returned to Trainz from TSW 4 and TSC 2024. The graphics and depth of Trainz I think is superior to other train simulators. The issue I'm having - which I don't believe is related to this particular route (Clovis to Lubbock) - is that I'm having all kinds of trouble getting trains to drive to trackmarks. Often either the train gets stuck, waits indefinitely for clearance, or attempts to route to a trackmark only to be derailed by a junction getting switched while the train is travelling over it. I must not understand something about how Trainz logic is changed, at least as it applies to issuing commands to drivers. Is there something obvious I might be missing??
