Bachmann Chattanooga coal Tender constantly derails

[choochooBrad]

Just set up the track last night and it appears as if the connection to the engine is being pinched when the train goes into a corner. I wish they had just used a regular coupler for that car because we could just run without it. I do not know if the frame of the engine is not aligned with the body and is causing it to pinch the plastic nub that rides in the groove between the body and frame? Any ideas would be helpful - my boy is very disappointed at the moment.

Brad-

The Chattanooga is a notoriously inexpensively manufactured, train set locomotive. I wouldn't count on it for long-term use
nor would I put a significant amount of time into getting it operation smoothly because something else will be a problem before
long. I believe you would do much better going on line to purchase a new loco without all of the gremlins you'll find in the
Chattanooga. In the alternative, check a recent Model Railroader for ads and you'll find some excellent prices for new,
reliable merchandise.
