[amp_mcq option1=”Track circuit\/axle counter” option2=”Circuit” option3=”Counter circuit” option4=”None of these” correct=”option1″]<\/p>\n
The correct answer is: A. Track circuit\/axle counter<\/p>\n
A track circuit is a device that detects the presence or absence of a train on a section of track. It does this by monitoring the electrical current flowing through the track. When a train is on the track, it interrupts the current, which is detected by the track circuit. This information is then sent to the IBS, which uses it to determine whether or not the line is clear for the train to proceed.<\/p>\n
An axle counter is a device that counts the number of axles that pass over a particular point on the track. This information is then used to determine whether or not the line is clear for the train to proceed.<\/p>\n
Circuit and counter circuit are not correct answers because they do not specifically refer to track circuits or axle counters.<\/p>\n","protected":false},"excerpt":{"rendered":"
