...600 feet of D types = 960,000 pounds/24 axles = 40,000 pounds per axle. ... Let's see. Each D-Type was 137 feet long, weighed on average 210,000 lbs. and was supported by 4 trucks each with 2 axles. Each car also carried 555 people @ 150 lbs each for an additional 83,000 lbs., bringing the D-Type weight up to 300,000 lbs That means a 4 car train was 548 feet long, weighed 1,200,000 lbs loaded and 840,000 unloaded and had an axle load of 37,500 lbs. loaded and 26,250 unloaded.
