I have used it successfully on most locos. BUT, I have some Bachmann locos that I have pulled the wheels out to EM gauge that work fine, and other Bachmann locos that fail dreadfully. It depends on whether the Bachman locos have a rubber retainer at the end of the axle. if so, the wheels wobble off when you clean them. An example is the 64xx, but perhaps other recent introductions would suffer the same consequences. I am rewheeling this loco as a consequence.
