A railway points control system has a stretcher bar lock rod and a lock blade connected to the lock rod. The lock blade has first 19 and second 15 components. A first adjustable coupling 16 is provided between the first component of the lock blade and the stretcher bar lock rod; and a second adjustable coupling 20 is provided between the first and second components of the lock blade. The first and second components of the lock blade are each provided with a position detection recess (17, 21 Fig.5), each for the detection of one points position, and the system further comprises a position detector 18 for engagement with the position detection recesses. The invention allows essential checks and adjustments to be carried out on railway point machines from a position of safety separated from trains. It also allows adjustments to be made more easily, more accurately and more often without creating delays to the railway. |
