Rail Switching Device for Turnout using Electrohydraulic Actuator and its Performance Tests

This study aims to develop a prototype of a new switching device of switch rails with a focus on labor-saving for the maintenance of turnouts.Initially, the authors designed and produced the switching device using the electrohydraulic actuator installed in bearer, which can control and monitor the displacements and switching forces of switch rails.Subsequently, a series of performance validation tests were conducted.As a result, we confirmed that the device satisfies the concepts and can operate the switch rails stably monitoring the switching forces and displacements of rails.
