Westinghouse Signalling Relays

All signaling systems provided by Westinghouse in the 1950's used their glass style relays, which looked a bit like a fish tank, the wiring is connected via terminals on the top of the realys. Below we can see Parsons Green relay room on London Transport. More details of individual relays are pictured below.
