I've been away from Trainz session creation for the last two years, but thought I'd give it a try with TANE. I have a train stopping short of an industry spur. I have the engine and 8 cars uncouple from the train, pull forward to clear the switch, then back into the spur to pick-up two cars. Here is where the problems start to occur. I have a track mark on the spur and use the Nav to Trackmark driver command, but AI refuses to throw the switch and back in. So, I tried the Path Rule and the Drive Path driver command. Now the switch stays locked in the position to the spur, and I can not get back to my train on the main. Is there a Driver Command that can be used to simply throw a switch and then throw it back when you are done? Or some other trick or combinations of commands?
