Light rail vehicle having predictive diagnostic system for motor driven automated doors

An apparatus for identifying when maintenance is required on a light rail vehicle motor driven automated door system, comprising:

• means for indicating a position of a door through open and close cycles;
• at least one data acquisition board electrically connected to the motor and the means for indicating the position of the door;
• at least one computer including a data collection program, an exponential smoothing algorithm, and a neural network,
• wherein the data acquisition board collects data from the motor and the means for indicating the position of the door as the door system cycles open and closed, the data collection program and the exponential smoothing algorithm calculate a set of input values based on the data, and the neural network determines a rate of degradation and an estimated time of failure of the door system based on the set of input values and identifies when maintenance is required on the door system.
