Abstract

See full text

To avoid a locomotive from travelling with a disabled sanding system, a method and system are provided for ensuring that the sanding system is not disabled if a primary speed reference used to detect the locomotive's speed is faulty. The method comprises determining a first speed measurement from a primary speed source; if the first speed measurement is below a setpoint, determining a second speed measurement from a secondary speed source; and if the second speed measurement is below the setpoint, disabling the automated and/or emergency initiated sanding control system on the locomotive.
