I am realy impressed with the service I received from Bachmann Service. My N scale Spectrum 2-6-6-2 Challenger released all it's factory installed smoke (burned out) when something went wrong with the Clubs electrical system at a recent show. I took it apart and found the motor was seized, freed it up but it still bound in one spot. I requested a replacement motor from Bachmann but they asked me to put the locomotive back together as best I could and send it back. They do stand behind their advertized Lifetime Warranty as I just received a brand new replacement locomotive last week.
