Location of point control means in a railway track installation

摘要

A track system has sleepers of predetermined width and at a predetermined spacing and a pair of running rails fixed to the sleepers. A switch has inner and outer transversely displaceable tongues engageable with the running rails and a pair of parallel hollow box sleepers of the predetermined width and at the predetermined spacing fixed to the running rails and on which the tongues are transversely displaceable. A drive rod extending transversely in one of the box sleepers is connected to both of the tongues so that a drive connected to the drive rod can transversely shift the tongues. Inner and outer position-monitoring rods extending transversely in the other of the box sleepers are connected to the respective guard rails.
