I wish I could help you, but I couldn't help posting to wish you luck, and to say Hi to a fellow 1/4 incher. We are rare on this forum. My husband and I are also O scalers, mostly standard gauge, but with a little bit of On3. You might want to get in touch with YO models, and ask them directly. I own a Sunset GE44 tonner that is standard gauge, and that has been converted to all wheel pickup.
GOOD LUCK!
Jennifer
I want to regauge on On3 Rich Yoder 45 tonner to either 33 or 16.5mm gauge. has anyone tried this and , if so, what are the pitfalls.
