NEW ALUMINIUM TRIPLE-HOPPER WAGON

In 1945 the American Car and Foundry Company completed the development of a triple-outlet hopper wagon having a nominal capacity of 70 tons and 2,840 cu. ft. with a light weight of 55,500 lb. The new type has a load limit of 154,500 lb. and the overall width is based on the A.A.R. unrestricted clearance of 10 ft. 2-1/2 in. The body is divided into three vented compartments which can be unloaded separately or simultaneously. The new car is 39.25 in. longer than the A.A.R. standard 70-ton steel hopper wagons, but can increase the payload by about 6.5 tons. The yield strength of the aluminium used is 38,000 lb. per sq. in. which gives a high factor of safety. The thick sheets and plates allows a long life when possible wear in handling abrasive materials is taken into account.
