Abstract
A fixedly mountable event recorder for a railcar for monitoring performance of a brake system thereof includes (a) at least one port for receiving air from one or more brake system components; (b) at least one sensor for determining a pressure of the air received from the one or more brake system components; (c) a processor operative for analyzing the determined pressure to determine an operational condition of the brake system; and (d) an indicator configured to visually convey the operational condition of the brake system. The indicator includes a plurality of activatable visual indicia corresponding to a plurality of predefined operational condition status qualifiers associated with a corresponding plurality of predefined ranges of operational conditions. The predefined ranges of operational conditions are defined as a function of expected pressures associated with the respective one or more brake system components during corresponding operational conditions thereof.
