What is the term for the designated track adjacent to a main track used for meeting or passing trains?

• A. Siding
• B. Single Track
• C. Two or More Tracks
• D. Yard

Answer: (A)

A siding is the designated track that runs alongside the main line and is used for meeting or passing trains. It provides a separate space where a train can pull off the main track, letting another train pass or meet, without blocking the primary route. This is why a siding is the best term here—it’s specifically the extra track laid beside the main line for those tactical movements.

The other ideas don’t fit this particular role. A single track describes the overall configuration of the line rather than the special passing track. Two or more tracks similarly refer to the number of parallel lines in a corridor, not the function of a specific track for meeting or passing. A yard is a cluster of tracks used for assembling, sorting, and storing cars and locomotives, not for passing trains on the main line.
