A visual diagnostic system for a railroad network is disclosed. The visual diagnostic system may have a sensor associated with a train asset in the railroad network and configured to generate a signal indicative of an operational status of the train asset, and a user interface associated with the train asset. The visual diagnostic system may also have a controller in communication with the sensor and the user interface. The controller may be configured to display on the user interface a graphical representation of the train asset in response to the signal.
