Modified Con-Cor MHC. How to: Cut off the ends of the frame just outside the last cross member. Turn the end pieces around at each end and the bolsters should now be in a little bit more of a correct spot, add MT BX express trucks and your ready to go. This one was a full repaint so I added the Kato MHC detail set to it as well. I did have to use the little spacer on the trucks too.
