I am beginning my first G scale (or any scale, now that I think about it) bash, a Santa Fe CF7. I am either going to do 2417, 2420, or 2427. I disassembled the USA GP7 I am using as a base tonight and am going to order parts soon. I am doing it for the Model Railroader kitbash contest, but if it does not win, I will send it to GR. I'll post my progress when I have time (which I hope will be fast because it has to be done by June.)
