Is anyone aware the date when P series relays were introduced and where was the first large installations carried out.Are there any large installations still employing P series relays left in the UK?

Slightly off topic - Tomteboda marshalling yard in Stockholm used P series relays (I say used as the room still exists but the hump it controls is no longer used). My one and only visit to the relay room left me feeling rather at home, with 'Alert' fuses, British nomenclature and circuits I could at least follow, if not fully understand at the time!

That isn't too surprising as Westinghouse had a number of contracts in Sweden including Malmo box miniature lever frame.
