Rich,
Many thanks. I suspect that the plastic connectors on the axels on one of the trains rotted, but the other ones seem good. Will follow-up with Backman service tomorrow.

Hi,
I recently purchased a "new" model 4454, (circa 1976; sill in box). It derailed and I, unwisely, allowed the drive wheel assembly to come free. I took it to a local repair store and was told, with a shake of the head, no way. Then I purchased another new locomotive  4446 (circa 1985) model. It ran a few feet and derailed. When I picked it up the wheels fell off. The plastic connectors between the wheels looked good so I began to reassemble, but was unable to get it properly quartered. I just received an NWSL quarterer (#44-4), but it doesn't fit, and I suspect that I should have purchased a #64-4.
I am new to this hobby and would love to resolve these problems.
Any advice or help would be appreciated. I am not certain if Bachman's warranty covers such things, if I should purchase another quarterer, send them both back for repair...

Thank you!

Michael C.
