UP 4014 Project

[nachoman]

Cool project. One question, does the Revell loco have a rigid frame, or does it actually articulate? If it is rigid, this could be a huge problem. If I was doing this, I would probably replace all the wheelsets except for the drivers. Even though they roll, they may not roll well. You will have to add weight to keep it on the track. Good thing the prototype had it's valve gear disconnected, because I'm sure that would cause a bind of the model and the plastic would wear out quickly. Not sure how the drivers fit into the frame, but any way you could replace the driver axles with steel?
