I have a freind who's a newbie in the hobby and he's asked me to have a look at why his Prairie 2-6-2 Isn't running. Thinking this was probably a simple case of a shorted wire against the frame, etc. I said O.K. Even though I've been in the hobby for several years, I havn't had much occasion to get into loco workings except for some of the popular locomotive kits and I'm not about to mess with any of my brass stuff. Anyway I'm completely stumped at how to get the superstructure seperated from the chassis. I've pulled the rear screw which was obvious and that area is loose but I can't for the life of me see what's holding the front section between the cylinders together and I don't dare apply force. I figured it would be better to get advice than break something.  Can anyone out there help me save face and at least get the thing apart??
