I've just finished my Lionel Turbine rebuild, mostly. I've replaced the axle bushings, motor, worm gear, smoker, and side rods. I've quartered the wheels and greased the gear. My first question is, should I "break it in" or just go ahead and use it normally? If I do need to break it in, what's the best way? My second question, is about the trucks. The front truck spring has rusted and broken off, which I didn't notice until after I had placed all my parts orders. The rear truck spring is in rough shape too. Do I need to replace them now or is it something that's not really important? I'm considering adding a switch to turn the smoker on and off. Does anyone have ideas on where to mount a small switch without modification to the engine? Has anyone else done it to their engines?
