The 14900 seriesTrack Simulator features a front panel with standard set up resistors and terminals and electrically conductive model track to simulate a track circuit suitable for instructional and hands-on training purposes. A locked drawer provides additional switches, potentiometers, and controls that allow selective implementation of many faults commonly found in typical track circuits. These faults may be activated individually or in any combination by the instructor and secured from view by the trainee in the closed and locked drawer. The result is a realistic simulation of track circuits with a variety of common problems that serves as an effective and practical training aid.
