-67- COST OF STEAM OPERATION. The steam locomotives used in the switching service on the Evanston Line of the C. M. & St. p. R. R. were of the Northwestern 1-5 class. This is a 0-6-0 type of switching engine having a tractive effort of 28,158 lb., a weight on drivers of 127,000 lb., and a grate area of 25.8 sq. ft. Com- plete dimensions and specifications are shown on the accompanying blueprint and table. This type of engine was used on the switch- ing service for the reason that it was the onl...y type of C.M.& St. P. switcher that was light enough to operate on the elavated structure. It so hap- pens that if its weight and tractive effort are calculated theoretically, they agree substantially with the actual results. As was ex|>lained before, the cost data on steam operation is largely of an arbitrary nature, and represents average costs on the Chicago Ter- minal Division of the C. M. & St. P. R. R. rather -68- than the specific cost of operation on the Evan- ston Line, To reduce these costs to the locomotive mile unit, three different methods were uded.
