I want to set up a scenario where a train runs into a platform, unloads its passengers, the loco runs round and then moves the train into a bay before loading. The problem I have is that I can unload the train with the terminate command, but when the loco couples up again, the slight movement of the carriage triggers the platform's load command so that instead of moving an empty train, it has unwanted passengers. Is there any rule or script that will stop this loading? Looking through them doesn't give me anything obvious.
