traction tire for steam loco?

[leon]

To all concerned: I have found the culprit! One of the passenger cars is the problem! I checked the trucks and found that the wheels darn near dissapear into the side frames causing all kinds friction drag!! This the cause of the difficulty on the up grade---on the level it appears to work fine. I guess I will have to send the car back to Bachmann for repair since it is a Spectrum train set.

Thanks to all; Leon
