摘要： A train detection mechanism for detecting the presence of a train on a section of track, the track section including first and second rails 1, 2 and delimited by first and second ends thereof, includes current injector for injecting current into the first rail at the first end of the section and current receiver for receiving current from the second rail at the first end of the section, and a shunt 3 connected between the first and second rails at the second end of the section, characterized in that the shunt includes a switch 4 for controlling current flow through the shunt, the switch being operable by the passage of a train.
