Railway Point Lever Lock Circuit & The Indication Circuit

Lever Lock Circuit  Every set of points which has a passenger move over them, must be track locked as discussed in 9.17. Another way of achieving this is to prevent the controlling point lever from moving. In many situations, both methods are used to prevent the points from moving when a train is upon them […]

The Detection Circuit Figs 1.12 and 1.13 show a typical detection circuit for a single ended right-handed set of Four Foots. To change the phasing of the ‘R’ side the BX and NX feeds need to be changed by 180º (R1 and R2 feeds swapped around). In the detection circuit this is achieved by using […]
