M/W COSTS: HOW THEY ARE AFFECTED BY CAR WEIGHTS AND THE TRACK STRUCTURE

Using a combination of theory and actual field measurements, the author develops the relative maintenance costs associated with axle loads and the type and condition of the track. The article attaches definite values to variables such as total tonnage carried, track condition and car size. The Illinois Central Gulf considers that 53% of total track expense and capital investment is incremental--varying with the tonnage moving over the railroad. This incremental cost is then broken into its own increments based on rail deflection, rail bending stress, rail life and miscellaneous costs.
