Once large pieces of machinery, such as earthmoving equipment, have been manufactured, they must be shipped to the buyer. This paper discusses the operations of one railroad, the Illinois Central, in handling this problem. Due to route obstacles, the railroads classify loads into two categories: those under 10 ft 8 in. width and 15 ft 1 in. height, and those under 10 ft 8 in. width and 15 ft 6 in. height. Loads beyond these dimensions must be routed with care to avoid the obstacles creating these limits. The method used by IC is described. Weight limits are similarly outlined.
