What is a siding used for in railway operations?

A siding is primarily used as a track for meeting or passing trains. In railway operations, it provides a way for one train to let another pass, which is essential for efficient scheduling and the continuous flow of train traffic on single or double mainlines. This capability is crucial in managing traffic and reducing delays, as it allows the train on the main track to continue its journey while another train temporarily moves into the siding.

Options related to freight handling and designated storage areas have specific functions but do not encompass the primary purpose of a siding in facilitating train movement. While scenic routes may enhance the passenger experience, they do not accurately describe a siding's operational function within the railway system. The use of a siding for meeting or passing trains is essential for maintaining operational efficiency and ensuring safety on the rail network.
