I recently purchased an O scale USRA heavy mountain locomotive. I hoped to modify it to closely resemble a 1500 series locomotive. I realize it may be off a little. I don't want to modify the boiler diameter or anything that dramatic. Will this be a pretty close approximation, or way off? Thanks!
Karl, you're good. Alan Hale would be proud. Although it describes an HO model, the following thread has good info: http://www.frisco.org/vb/showpost.php?p=10193&postcount=17 A USRA light mountain is pretty close; a USRA heavy mountain is still close enough for my tastes.
