Don, good to see you still up to your old tricks with older trains ! Yep, we're both die hard train guys. I'm still up to my old tricks too, but albeit with slightly more recent types of trains . And mostly redoing things I already have or making changes and improvements. It was painful, all the trains I had to get rid of. And as always with hindsight, I'm kicking myself hard over a handful of them I wish I'd had to foresight to hang on to.
I can't help you with your latest project, but I'm sure you'll get it working!
