Ping-Ping: C'mon Jordan, hurry up. Help us out here, please mate!
Erm, don't know boss. I had one of the lovely Red Caboose GP9 locos here for a while until a mate spirited it away about a year ago. My guess is 'yes', but I think Jordan has one of the drive sets in one of his locos, so he'd be a better man to ask...
I'll be interested in the reply too!

Sorry Steph - this thread has taken off since I last looked...!! Now I'm catching up at work, so I can't just pop up the shed and measure some axles either.... :
:-[
Offhand I
think the axle dia. is the same as UK; I've used sprockets from P&D with Delrin chain okay,
BUT...
(and it's a
big BUT....)
I have to say I'm not that impressed with the Weaver drive method - not as smooth as new Atlas stuff, and not much of an improvement over the original 1970's Atlas drive (central motor/gear towers), and yes the current draw is horrendous- I have a 1-1/4 Amp handheld controller that struggles to give my GP40 any decent speed - lash it up with my F7 which is also Weaver drive and they barely move!! It is also a bit noisy compared to Atlas/Heljan, (like my Delrin Class 22), despite lubrication.
It could all just be me, of course, and the effect I have whereby something that works perfectly for everyone else simply falls to bits in my hands....
My Red Caboose GP9 has the '70s Atlas drive but with flywheels, which transforms it - I have spare flywheels to fit to my FP7 (same drive) to see if they'll help there.
I'm actually considering getting a second original Atlas chassis for the F7 and ditching the Weaver drive. The GP40 is stuck with it for now.
Sorry this is A) not much help with the axle dia. question, and B) a bit of a thread hi-jack....
