The Silver San Juan
Well, I've finally had success in this endeavor. Using Elvenor's script, I've managed to get interactive rear marker lamps on a caboose. They'll even swap ends if you move the caboose to the other end of the train. The other goal I'd hoped to achieve for a few months now was rear marker lamps for my tenders. Well, I successfully combined Elvenor's script with the script that Wulf wrote for my tender hatches. And it all works!
