I'm still basically a DC guy, but am coming up with a limited roster of DCC equipment to run on others layouts and shows. I've done a lot of custom builds on my Climax kits with DCC now, not a total Luddite.
This project was taking one of the old Life-Like plastic frame PA's and putting a DZ126 in it - easy enough as lots of room in there, plastic frame, and it pulls like a mule, great contact. A fairly inexpensive project, too.
But - the ATSF ones had a mars light in the high nose and a headlight below that. Hmmm. How the heck do you do that without the extra F1 bulb leads? I'd read it could be done.
Finally decided to just ask.... and got a good answer in 24 hours, which CV's to set to what and it worked great. Just what I wanted. Mars light looks good and is controllable off of F1 off the rear headlight leads.
So I like to salute good support when I see it, as an old IT guy i've seen a lot of BAD support.
