Dwell time measures which aspect of rail service?

• A. The time it takes for a train to travel from its origin to its destination
• B. The official schedule listing departure and arrival times, routes, and service frequencies
• C. The time a train remains at a station for passenger boarding and alighting
• D. The time interval between successive trains

Answer: (C)

Dwell time is the period a train sits at a station to allow passengers to board and alight. This is distinct from travel time, which is the time the train spends moving between stations, and from a timetable, which lists scheduled departures, arrivals, and service frequencies. It’s also separate from headway, the interval between successive trains on the same line. Dwell time matters because longer pauses at stops can delay the overall trip and limit how many trains a line can handle, while shorter, well-managed dwell times help improve reliability and capacity. Factors like passenger volume, door operation, and safety procedures influence how long a train stays at a station.
