The smoke unit is from an MTH PS-1 4 Truck Shay (20-3023-1) which was in there 1997 catalog.

A foil trace on top of the board has failed and is a bit beyond my ability to fix things, or so it seems anyway.  In looking at the MTH Parts listing on their site for this engine the smoke unit is shown as the standard AA-0000011 PS-1 unit, however once I got my hands on one it only sort of resembles what I found inside.

So with photos below of what I actually found inside does anyone have a part number they can pass along and better yet a source to obtain a new one from, or at least the top board which is all the problem appears to be.

The apparent problem is the fried foil trace at top center.
