Selecting branch of railway points - involves guide elements which are alternately raised and lowered to position adjacent to permanent lines

摘要

The device can select which branch of track a rail car is to take. The lines (1 to 5) are permanently fixed, and in the crossing sections (2,3) recesses are formed which accommodate profiled elements (6,7). These elements (6,7) are alternately raised or lowered by hydraulic or pneumatic power housed underneath the crossing, on a pivoted cross arm (8). USE/ADVANTAGE - Railway points provide a reliable guide for the vehicle wheels.
