I'm having this problem with scenario designer with TSW4. After placing a few consists the stations and sidings stop being marked so i no longer know what stations etc I've already placed consists at. this causes further problems as you can place multiple consists at one place. When I start the scenario there are 3 consists all mashed together on a platform. If I set 3 different departure times all consists will leave one after the other at the final departure time for the final consist and will all occupy the same signal block.
