Disclosed is a light rail vehicle having a predictive diagnostic system for a motor driven automated door ( ) to enable condition-based maintenance. The light rail vehicle ( ) has an automated door system ( ), at least one data acquisition board ( ), a data collection program ( ), an exponential smoothing algorithm ( ), and a neural network ( ). The need for maintenance is identified through the collection of various door system ( ) parameters, calculating current energy and time consumption from these parameters, and determining the rate of degradation based on current energy and time consumption of the door system ( ) as compared with historical energy and time consumption. From the rate of degradation, maintenance can be scheduled as needed.
