MEASUREMENT AND SIMULATION OF FUEL CONSUMPTION IN RAIL FREIGHT SERVICE.

Fuel consumption measurements have been carried out in cooperation with several railroads for a variety of types of revenue freight service. Intermodal operations have been emphasized, but this report also includes studies relating to branchline and general freight movements. The widerange of operating parameters examined include train speed, weight, length, type, power-to-weight ratio, and terrain. In particular, this report describes the test conditions, operating parameters and fuel usage indices for 85 separate line-haul movements on six different railroads, covering 52,700 train miles.
