I can,t envisage exactly how your layout works so I can,t pinpoint the cause of your problem. However I can give you a few pointers in the right direction. You said the trains emerge from the portal and stop? So it is not a portal problem. That suggests either a pathing problem to the station or the location you want the driver to go to. You said when you swapped platform numbers around the opposite effect occurs. That would suggest the location is the problem. Here are a few testsfor you to carry out although I get the feeling you may have downloaded the station which is faulty? Place a loco with driver outside portal (s). Select driver Command "drive to" and check to see whether the name of each platform you want to go has been duplicated. If so that is the problem. By the way I,m not certain whether your "platfoms" are part of a station industry (I think they are) or a red track marker at the station. Next instuct driver to "drive to" (platfom x). If driver stays put, assuming platform is part of an industry, place a track marker next to far end of platform and call it "test 1" Instuct driver to "drive to" test 1. If the driver still doesn,t want to know you have a pathing problem. If the driver disappears into the sunset you have an industry problem. Repeat test for each portal and platform as appropriate and post your findings. If it is an idustry problem there is an easy work round.
