bell buzzer codes railway

How many bells does a train send to box a?
Box B sends 2 - 1 bells to box A (Train out of section) after confirming that the train has arrived complete and no portion of it remains within the block section between A and B or the clearing point for that section. This could be done by the guard of the train notifying the signalman or by the signalman observing the tail-lamp.
What is a bell code on a train?
Bell codes, buzzer codes or Communication Signal Appliance codes entail a series of bells or buzzers used on passenger trains for communication between the driver and guard . All codes, except 3—2—1, must be acknowledged by repeating the code received. In the United States, these are known as Communication Signal Appliance codes.
What does a buzzer message mean on a train?
When used, the buzzer message must be repeated back to the sender by the recipient to signify full understanding of the message. The most common code likely to be heard by the passenger will be the guard sending '2' (ready to start) to the driver, who then repeats back '2' to the guard and starts the train.
Why do drivers tapped out codes on a buzzer?
To provide concise communication, a series of codes tapped out on a buzzer was developed. Although nowadays it is more than likely that drivers and guards can talk directly through a telephone system, the codes are retained because each message has a very specific meaning. In a safety-critical environment, their use prevents misunderstanding.
