Abstract

See full text

A system for recording railroad track curvature utilizes linear motion transducers between the tracks of a railroad vehicle and the sides of the vehicle, or between adjacent vehicles, to continually measure the degree of curvature together with speed, stopped time and distance. A conventional event recorder is used for actual recording of the curvature information as a trace, which may be recorded on a conventional channel not then in use, such as the dynamic brake set up signal. A switching circuit substitutes that signal for the curvature signal immediately upon the dynamic brakes being applied. Thus substituting load (amps) for the curvature signal in the trace being recorded.
