Hi guys. So, assuming you have the above turned on and a random activity event occurs which identifies, say, "Car ID 0-25" with a problem, what happens if you have TWO cars with that ID in the consist? In my case I uncoupled the rear one as that was easiest but then got the randomization message back once I'd recoupled up to the consist, so I ended up uncoupling the other car 0-25 nearest the locos as well. Did I need to uncouple both, or was the system just seeing the car nearest the loco at the front of the train when it flagged up the hotbox problem?
