Thanks guys for all the info. This does have a "Fake" coupler in front, does run by itself & the rear truck (metal wheels) looks right under the cab. The bottom Drivers Cover is factory marked into the plastic "Bachmann". There are a pair of coil springs held on the front position for the leading Truck by a slotted screw. Looking at the current offering I have found a front Truck that may work p/n H11410 as a replacement for p/n 3004 (original) that they say doesn't exist??? I have left several message requests to speak to a "Supervisor" but I think they really don't care as they never have communicated with me. I can't even give them $$$ for "Smoke"!!! I do think 1970's is correct for this according to my friends recollection & the Original Box says U.P. but that was an option as well. I need to know more about the "Sound Board" & how they are "Powered Up". It says on the board "Kader 8011" which is "Bachmann". It has 3 wires going to a "Uni-Directional Power Plug" but uses only 2 of the wires. This is a "D.C. Motor" as my Layout is. I can bring power to it from wheels, but as the "Polarity" changes, how does that effect the "Board"

I guess they could use a "UJT" to make it go both polarities??? My understanding is that Sound Boards don't really have anything to do with Direct Computer Control Systems (not dependent upon), but that was the "Factory Girls Excuse" not to talk with me, sending me to a Supervisors answering machine. I guess they don't need my $$$? John
