Does anyone know of a source of new wheel and gearsets for the old Tri-ang EM2 power bogie? A significant number of my existing ones I suspect have been worn oval (the plastic gear wheel). I am aware of the very nice Ultrascale items but they are way too slippery to allow the loco to gain traction so want to avoid them. Halfway house would be a replacement axle and gear to use the existing Tri-ang wheels I guess (I'm using code 100 track).
Thanks in advance
