摘要

The device has 2 direction detecting axle counters (1.1,1.4) remote from and 2 (1.2,1.3) close to the transition (6). One remote and one close counter are arranged on the left and right sides of the transition. Three counter sections are provided by adjacent counters. In the event of a fault in a close counter a higher priority counter section is formed between the left remote and right close counters or left close and right remote counters.
