UCR & USR relay interlocking circuit
#1
Hi Signalling Professionals:

Can anyone explain the function of UCR Route Check Relay and USR Route Stick Relay, and the purpose of those 2 circuits?
and the meaning of these 2 relays when they are in the "pick up" state or "drop off" state? (i.e. route checked, or not checked etc.)




Thank you




Bill
