Lubrication of engines. My son and I have complete a N scale layout. I've noticed that the "hand me down" engines he received from one set of grandparents, operate very "jumpy" and sometimes not at all, unless we take the engine of the track and work the wheels (they are old engines). Now his new engine has no problem at all with the track and runs very smoothly.
I'm assuming that there is some kind of maintenance that is needed on the engines to keep them operating properly. If there are links to web sites, that would be nice too. Any suggestions on the lubrication of the engines would be greatly appreciated.
