[amp_mcq option1=”Signal over lap” option2=”Over lap” option3=”Block instrument” option4=”None of these” correct=”option1″]
The correct answer is A. Signal overlap.
Signal overlap is the adequate distance kept beyond the starter signal to take off the home signal. It is a safety measure to ensure that the train has enough space to stop if the starter signal changes to red.
The other options are incorrect.
- Option B, overlap, is not a technical term in railway signaling.
- Option C, block instrument, is a device used to control the movement of trains in a block section.
- Option D, none of these, is the incorrect answer.
