I occasionally buy Lima European and British locos in O gauge from the 70's. Last week I bought a rather nice French Diesel.
I buy these in the hope I can convert them into a suitable 3 rail loco from a donor 3 rail loco I already have. And this time I was lucky. I have a Lionel EP5 with TMCC and a Pullmore motor, a relatively recent re-release. It's a nice runner and I have another EP5. As it happens both the EP5 and the French loco have almost exactly the same wheel bases, chassis length and width. All I had to do was trim a little of cowling off both ends of the body to allow free movement of the trucks and grind about 1/8" off the ends of the chassis. Even the cab interiors with driver and offsider fitted perfectly from the EP5. I just added some extra Evan Design LEDs to both ends, and hot glued in a brass plate for the antenna, and fit the mounting brackets, and I've now got an unusual modern era French diesel. The trucks are still EP5, but I'm not a rivet counter and it looks good enough for me. Has anyone else done this?
