This is the 1-ton capacity cost per type of car and calculated by dividing car capacity into the average cost of car, plus the result obtained by dividing the total number of tons-capacity of the train into the cost of the locomotive. For the purpose of this study, a single unit Alco-Ge No. 1600 locomotive is considered as hauling what would be an average train over varying terrain; 1,600 gross tons, from information furnished by the builder; Erie Railroad uses 4 units to haul 5,450 tons eastbound and 4,000 tons westbound between Marion, Ohio, and Salamanca, N. Y.; Mopac uses 2 units for 5,000 tons and 3 units for 9,000 tons between St. Louis and Southwest; New York Central Railroad uses 3 units for 3,200 tons from Selkirk, N. Y. to Springfield, Mass.; Union Pacific Railroad uses 4 units for 3,000 tons eastbound and 4,000 tons westbound over Cajon Pass.

From calculations based on information in Transport Statistics the total revenue and nonrevenue 1,000 ton-miles freight, 664,521,565 is divided into total maintenance costs for locomotives and for freight cars; obtaining costs of $0.59 for all types locomotives and $0.86 for all types of freight cars per 1,000 ton-miles net. To this is added the proportionate costs of superintendence $56,132,892, shop machinery $22,882,406, and power machinery $4,284,743, deducting nonpertinent costs.

From Fuel and Power Statistics of Class No. 1 Railroads in the United States (I. C. C. statement M-230 (OSE)). For 4 months ending April 1957, 1.74 gallons Diesel fuel per 1,000 gross ton-miles including locomotive. The amount of 4.21 gallons per 1,000 net ton-miles of freight is obtained by dividing the total number of gross 1,000 ton-miles of freight trains, 1,616,207,357, by the total 1,000 ton-miles of freight, 664,521,565 and multiplying the result, 2.42 by 1.74. (Ton-miles from Transport Statistics.)

10 Ton-mile figure for labor productivity is obtained from calculations based on information in Transport Statistics, and I. C. C. Statement No. M-300, Wage Statistics of Class 1 Railroads in the United States. 1956. The total of freight train and enginemen thus classified in the statement is 94,580 and to this number is added the number of yard engineers, motormen, firemen, helpers and conductors who may be engaged in the handling of freight trains. Since the statement provides no breakdown for freight and passenger yard men, it was necessary to find some basis for such a determination. This was done by calculation of the percentage of passenger trains-gross ton-miles, of the total transportation service-total gross ton-miles (which includes everything freight and passenger), and which amounts to approximately 15 percent. On this basis 85 percent of yard men were determined to be engaged in freight service; 99,185. The total of 193,765 employees is then divided into the total of revenue ton-miles, 646,519,282,000, and results in the amount of 3,336,615 ton-miles per transportation employee. (Passenger trains, total gross ton-miles, 274,801,085,000; transportation service, total gross ton-miles, 1,891,008,442,000.)
