FUEL EFFICIENCY IMPROVEMENT IN RAIL FREIGHT TRANSPORTATION: MULTIPLE UNIT THROTTLE CONTROL TO CONSERVE FUEL

During tests performed in conjunction with the Burlington Northern and Union Pacific railroads and AMTRAK, significant fuel savings were realized by using a semi-automatic throttle control device or fuel saver system to take one or more units of the locomotive consist off-line when the available power and tractive effort exceeded the demand. This procedure effectively lowered the horsepower per ton ratio of the train, improved power management in various terrains, and decreased the rate of fuel consumption.
