Westinghouse M63 Style Point Machines
The M63 was a development of the Style M3A machine, the M63 was supplied to British Railways from 1968 onwards. The Style 63 is a 'combined machines' in that they contain not only drive and locking mechanisms but include in their circuit-controller compartments electrical detection contacts which prove that one or other switch blade is fully closed against its stock rail and that the points locking bar is fully engaged in the locking slide.
The M63 point machine in a training school environment. The motor [130vDC] is seen at the top, the drive shaft is in the center are and all the electrical detection connections are at the bottom of the picture. This setup is used to allow signalling technician to test out various mechanical and electrical scenarios by adjusting / mal adjusting the point motor to see what happens within the point motor. In this setup this motor can be power worked from the location in the background. Picture reproduced by kind permission of Ian J Allison
The M63 point machine in a training school environment. The large external steel bar is a mechanical linkage between the point drive connection in the centre of the machine, this is tied to the 'red' facing point lock bar and the two detections rod connections on the left hand side of the unit. This setup is used to allow signalling technician to test out various mechanical scenarios by adjusting the nuts on the left hand end connections, and then hand wind the point motor to see what happens within the point motor. A they say a really useful setup teaching aid.
