Reply to "CONVERTING MTH 72FT CENTERBEAM'S FROM 3 RAIL TO 2 RAIL TRUCKS."

Newest project this is one of the very few accurate paint schemes from MTH for these cars, the prototype was an 86/87 Thrall car with the correct shorter truck spacing used I believe because of the 10'+ solid centerbeam paneling inboard from both ends before open posts. I have added end details plus Atlas 2 rail trucks would look better with the newer Atlas thin frame trucks, big advantage of Atlas trucks is ease of mounting a 10-24 3/4" machine screw and nut along with a suitable spring from any ball point pen with a fat spring works great, remove frame and mount trucks nut just fits round back side of frame after remounting frame trucks can be removed and nut stays in place without turning. I took this a step further by filing down top screw on plate of trucks to near flush with inside lower mtg post this is as low as you can bring carbody with out hitting tops of 36" wheels on under frame on curves still requires spacer under KD 706 long shank box about 1/32"  more if you do not file truck tops I make mine from sheet styrene , car is still to be touched up and weathered. When MTH first introduced this car some catalog pics were of HO model with correct truck spacing.
