I suppose you could scratchbuild a new frame, but ordering a new one from Athearn would be easier.

OK, so you don’t want to buy a new frame. Is it possible for you to saw slots in the broken ends with sufficinet accuracy that when the frame halves are re-mated the slots match up exactly? (I’m thinking as viewed from the top) If so, can you get metal strip say copper, as thick as your saw blade? Insert the strip into the slots in one half of the broken frame, and make sure it’s a tight fit. Electrical continuity is what you’re after. Now mate up the other half, and before the halves just meet, inject a gap filling ACC . The glue should bond the halves, and the strips should hold them together adding strength and allowing electrical continuity which you need for power routing through the frame to the motor. Make sure the whole thing is square before the ACC sets up for good.

As the folks said, buy a new frame, unless you’re trying to atone for your accident. [;)]
