ESTIMATING EFFECT OF HEAVY WHEEL LOADS ON RAIL LIFE: ROLLER BEARING ANALOGY

There has been considerable controversy as to the cost of operating unit trains consisting of 100-ton cars. Part of the problem was difficulty of estimating the cost of track maintenance. This paper utilizes roller bearing theory to offer a way to establish at least a part of the total cost.
