There is no humming. The engine is only 3 years old, and I am the original owner.

My 4-6-2 steam engine won't run, but the headlight still lights up. What should I be looking at?

Will 85' passenger cars operate on 18" radius track?

My new 4-6-0 runs inconsistently, slowing down on straightaways and speeding up on turns. Any suggestions, or does it just need a drop of oil?
