Dear Bach-Man,

we have a Disney Lilly Belle 4-4-0 HO train.  A year ago we sent in to be repaired, because a long plastic rod had fallen off the engine/tender.  All was fixed, but it has happened again.  We were just looking at it, it was not even running.  If we try to run it, the lights turn on, the engine runs, but the wheels do not turn.  What and where does this 2" plastic piece go?  Do we have to send it back in to be repaired or can I do this at home....frustrated.
