Abstract: A method, system, and computer readable medium may be provided for train monitoring. Track circuit data may be received including an indication of a shunted track circuit on a train track. The received track circuit data and shunted track circuit may be analyzed. A train may be tracked on the train track based on the received track circuit data. A loss in physically expected track circuit occupancy in a path of the train may be detected. A graph may be generated showing the at least one shunted track circuit over time. The graph may indicate losses or abnormalities in physically expected track circuit occupancy in the path of the train, velocity of the train, acceleration of the train, and/or a size of the train. An alert with the severity and track circuit identifier may be generated and transmitted.
