Abstract
The invention relates to a portable device for measuring lateral rail measurements under service to record and report excessive rail movement and angle differential to prevent a train from derailing. The device may be spring-loaded and light-weight. The device may include a microprocessor, sensors, and a display. The device may be installed on the rail. The device may sense an approaching train, automatically turn on the device, detect the train speed, and measure the angle differential, the real-time displacement, and the maximum/minimum displacement between the two rails while the train is operating over the rail at all speeds. The device measures and records the separation and angle differential of the rail to ensure the rail does not exceed separation that could derail the train.
