I think there is a bug in the script. I had several AJS Invisible stations and getting the trains to stop was a hit and miss. Some times a train will stop, other times it will pause and speed off. This occurs after the Call At, Navigate To, or Drive To, commands were issued. The next command was not carried out, usually a load command and any other command which followed, if it was track mark that was passed, the train would stop, back-up, and then carry-out the next command, sometimes!
