Dug the K27 out tonight, to check out the drive train. Finally! Have discovered that I have at least 4 loose counterweights on the locomotive!! Does anyone know how/where I can have the drive train repaired, so I can actually run this locomotive again?? Somewhere that will NOT break the bank?? I can NOT order new counterweights, direct from Bachmann, as they do NOT have the parts in stock any longer. Prefer local, as I'm not sure I want to ship this beast!! Any and all information is much appreciated!! Thanks.
