The Leaning GP50

[cmsluss]

Greetings N Scalers....

A couple of questions regarding Bachmann GP50 (analog).  For some unknown reason, my GP50 "leans" slightly toward the engineer's side (short hood forward).  There are no obstructions under the frame... the split frame design only has the motor and gears inside... so my question is why would it lean?

Also... for some reason... this unit runs very smoothly forward (short hood forward)... but... in hesitates in reverse.  Again, no clear indication there is anything impeding electrical pickup.  The wheels and track are clean, all contacts are in place.  Forward direction is fine... reverse is hesitant with speed variations.

Thanks for your input!
