Frankly, I can't remember if there were batteries on that side, too, or if it was an air valving. The picture I have of a Frisco unit missing the very same door appears dark inside and I can't see what's in there. Further, it's been so long since I've run/been around GP7's that I can't remember either. I know on GP38's, 40's, etc, there were air valves were under the floor on engineer's side, and I think over under the Fireman's side, too. (I've had to change them out doing an FRA required scheduled replacement)
Anyway... I've thought about using a modified triple valve casting with some brass wire for piping inside that empty styrene box that I created, but I need to see if that's what's really inside on the prototype first. Once painted, the styrene box I built inside the open door will be painted black so you won't be able to see much in there anyway.
Joe! (Toth, right?)
How 'ya doing?
I gave up on S scale several years ago. I simply missed the huge variety available in HO. S is a great size crippled by a tiny (compared to HO) offering of product. From the looks of it (the demise of SHS, and now MTH/etc), I know I made the right decision in view of where I wanted to go with my model railroading.
V scale as a hobby outlet for me is safe and sound. I still indulge every now and then, but I've come to prefer to invest my time into my model railroading instead.
Good to see yer still kickin'! I love being retired. Had I known it would be this much fun, I would have retired when I was in my 20s.
All fer now.
Hm... perhaps I need to post the story of #427 later today?
All fer now.
