First thing the tutorial asks you to do.... Switch on the locomotive tail lights in cab 2. *FACEPALM* WHY on earth would you ever do this, when you have rake of vans coupled to the back of the locomotive? Tail lights are used to mark the BACK of a train, so the guy in the signal box knows that you have no wagons missing when you pass his signal box. So you are never going to have a tail light between the loco and the stuff it is pulling switched on. It's just common sense. Oh, and they forgot to put a tail lamp on the back of the tutorial train (and some of those in scenario mode) too. Which breaks every regulation in the book... Can it really be that hard to script a tail lamp on the rear wagon?
