Yep. Nothing has changed. Before I set up the subway, I could turn the speed control on the Cab-2 and the bumper lights would come on. After I set up the subway, the subway runs fine but the bumper lights never come on.
When I was using TMCC, the bumper lights would turn on as soon as I started up the track power. I thought that's what should happen with Legacy, regardless of what's going on with the subway.
