I would like to model an HO Utah RR MK-50-3. Does anyone have any info on the dimensions of the cab and trucks for these units? The body is basically an SD50 (71'3") with a larger fuel tank. The big changes are the trucks(shorter) and cab(shorter). I contacted Boise Locomotive Works, who were the folks that purchased MK's ops, and with no success, no-one returned my emails or phone calls.
