Abstract

See full text

A method to determine fuel consumption, energy consumption, or both fuel consumption and energy consumption, during one test train run, or a plurality of test train runs, that is associated with modifying an operating parameter is provided. The method includes determining a reference fuel/energy consumption, and a cumulative ITE for one, or a plurality of reference train runs (CITERR) over a portion of track, and correcting the reference fuel/energy consumption using the CITERR of the one, or a plurality of reference train runs, to produce a corrected reference fuel/energy consumption value. The operating parameter is modified, and a modified fuel/energy consumption and cumulative ITE for the one, or a plurality of test train runs (CITETR), over the portion of track is determined, and a corrected test fuel/energy consumption value is obtained by correcting the modified fuel/energy consumption using the CITETR of the one, or a plurality of test train runs. The corrected reference fuel/energy consumption value and the test fuel/energy consumption value are then compared to determine the effect of modifying the operating parameter on the fuel/energy consumption during the one test run, or a plurality of test train runs.
