Which statement best describes Single Track Operation?

• A. The operation of trains in both directions on a single track
• B. Operation of trains in only one direction on a single track
• C. Two parallel tracks with bidirectional operation
• D. A single track with passing sidings

Answer: (A)

Single Track Operation means trains traveling in both directions share a single track. Because there isn’t a second track to pass on, schedules are arranged so trains don’t meet on the same section; passing sidings or designated points let one train wait while another passes, enabling bidirectional service on the same line. The other statements describe either one-way operation, double-track layouts, or sidings as a feature, but the essential idea is that the same track carries trains in opposite directions.
