Just received yesterday the Bachmann EZ Command Digital Command Control System with
DCC-Equipped HO Locomotive.  After putting the engine (GP40) on the track, I hear a grinding
noise from the engine.  I have a DC GP40 and it doesn't sound nearly as bad as the DCC engine.
Does anyone know about what this grinding noise is?  Should I send it back to Bachmann?
Thanks.

Hey guys.

Have a GP40 Bachman.  THe stock PCB has no inductors or capacitors, yet the old board in the
parts list has these electronic items.  What are they for?  lights?... something else?
