Are you sure about those weights? Not quite apples to apples but a built up three piece 70-ton roller bearing truck with truck mounted cylinders and 34" wheels weighs 8,500-9,000 pounds (I have the exact weight somewhere). 50-ton trucks are 750-1,000 pounds less while 100-ton trucks on 1,000-1,500 pounds more.

Date: Thursday, October 5, 2017, 2:39 AM Dave, you might enjoy my article in _Model Railroad Hobbyist_ in the issue for September 2016 (download or read on line, for free, any time, at their website, www.mrhmag.com ). You will find all this discussed there. Bolsters weighed 1000 pounds or more, as did side frames, and then add the spring planks (if any), spring packages, and brake linkage. Most freight trucks in the transition era weighed between 12,000 and 14,000 pounds.
