Bob,

Can you tell me what the wheel base is? NWSL has some 2 axle drives and Lambert Locomotive Works makes an underfloor drive for the Corgi PCC that could be candidates.

I happen to have my personal LIRR critter kit apart on my workbench right now, so I have included some photos to help you. The Lionchief Junction type donor frame that your kit was designed around has a wheelbase of almost exactly 2.5", as shown here.

Lionchief chassis wheelbase 2 1_2 inches

The entire motor frame is made of plastic, so you mostly have to worry about insulating the axles. Ground is picked up by brass contacts wiping the steel axles. I'm not very experienced with 2-railing locomotives (I just design new bodies for existing frames), but I would think that if you could just insulate one wheel on each axle and split the axle wiper in half, you could pick up one rail on each axle. Of course, the real trick would be finding or making the wheels-- particularly the geared wheels-- that would fit the existing axles.

Hope that helps, Ken

I think @Trainguy Ken covered the main points. By the time you modify the LC chassis it might be better to find a 2 rail donor. OTOH- the right wheels and axles might match up with the rest of the drive.
