How did torn-tape relay centres speed up military messages during World War II?

During World War II, torn-tape relay centres were established to expedite long-range communication between military homelands and distant theatres of war. These centres functioned by allowing tributary stations to forward messages to major hubs, where operators could then retransmit them quickly by physically transferring the perforated tape from the receiving position to the appropriate transmitting position. This manual relay process allowed for the efficient routing of teletypewriter messages across vast distances, ensuring that commanders in the field could maintain rapid communication with headquarters.1
