Sorry been off line for a while, Yes the Locomotive in Question is a 2-6-0, Northpole and Southern original set. I'll have to attempt to remove it by sliding the whole assembly forward and see what happens. And I agree there is not a screw shown as holding the upper body to the frame other than the one that appears to go through the smokestack. All the guy the does worki for me and I were able to do was damage one sanding pipe. Sure would be nice of Bachmann printed up a better blown up drawing of the locomotive. or maybe a spot on youtube.
