It was awhile before I realized this thread included locomotives, so here is my "Frankenstein" loco,..
THe story goes like this, years ago I bought an early Williams SD-45 with the idea of converting it into an SD-38. When I was ready to start the project, I opened the box and immediately noticed those Trainmaster trucks. Ugh! no way I can use those for an SD-38, so I decided to make a trainmaster. The shell is an MTH version, with Precision scale details, Scale coat paint, Shell scale decals, ERR sound commander and Evans designs LED Head light.
BTW I did eventually acquire another Williams SD-45 with the proper 6 wheel trucks, so that project will be done one day.
