Hey everyone! Recently I purchased the Santa Fe set from the local model store which included a Baldwin 2-8-0 with onboard DCC.  Just to make sure the engine worked, they connected it to the in store model layout to test it to see if it worked on both DC and DCC.  (They were really thoughtful!)
Currently I use it on a small temporary DC layout.  For the week I've had it everything has been running smoothly until tonight when I came to run it around the track, there was this terrible grinding/squeaking noise whenever the train moved forward.  The noise does not happen when it is in reverse.  I know for sure it is coming from the wheels.  I checked the bottom and nothing is sticking out and interfering with the tracks.  Unfortunately I think it is an internal problem.  Any suggestions on what to do?
