Continuous linear route control telegram traffic maintenance - using intermediate loop at changeover point connected to track equipment both sides

摘要

The system provides uninterrupted flow of telegram traffic, in the course of linear route control, between sets of appts. along the track and vehicle-borne appts. An intermediate line conductor loop is provided at the area boundary between two adjacent track sets, with connection to both of these. On area change-over in telegram traffic, operation with one set can be continued until the next indicates readiness for take-over. This obviates any need for a break in data provision.
