Abstract

This report presents the test results of SENTRAEN, a new top-of-rail lubrication system developed by Tranergy Corporation. The system was evaluated at the FRR Transportation Technology Center near Pueblo, CO. The concept of top-of-rail lubrication has demonstrated that it significantly reduces both the energy needed for trains, as well as the lateral wheel/rail loads on curved track. However, it was not possible to determine the exact amount of energy saved as the lubricant application rate left a residue on the rail which eventually led to locomotive wheel slip in the following trains. Electrical energy savings with this system, not including energy generated in dynamic braking, ranged from 23% to 30%. The average of maximum lateral forces developed in a 7.5 degree curve showed a reduction of 68% on the high rail, and 48% on the low rail, compared to dry conditions.
