LATERAL RAIL PRESSURES DUE TO LIGHT LOCOMOTIVE CONSISTS

A series of tests were performed to determine the lateral pressures against curved rail due to various light locomotive consists under various operating conditions. Analysis of the data indicates that an 8-unit consist generates somewhat higher lateral pressures than does a 5-unit consist. However, these pressures are less than half the pressures generated by head end and helper locomotive consists under heavy load. It was further noted that 6-axle light locomotives generate greater lateral pressures than 4-axle light locomotives by a factor of 30% to 60% depending mainly on speed. The pressures due to dynamic braking are the same as or less than the pressures generated by the use of air brakes. In both cases, these pressures when braking are about the same as pressures when coasting around a curve.
