Request stop

How it works

Procedures differ by operator and mode of transport but share common elements. A person waiting at the designated stop must make a clear visual signal so the driver can see them. Passengers already on board typically inform the driver or press a request button in advance. On some services the stop can be pre-booked so it appears on the crew’s manifest or the vehicle’s routing system.

Typical signals and systems

• Visual signals: standing visibly at a marked point, waving the hand, or using a flag or light where provided.
• Onboard requests: push-buttons, pull-cords, or informing staff to request the next stop.
• Advance booking: phone or online reservation that activates the stop for that journey.
• Audible acknowledgement: historically a horn or whistle from the train to confirm a request; modern practice relies on crew communication.

Uses by transport mode

Request stops are common on rural bus routes and branch railway lines where passenger numbers are low; they reduce unnecessary fuel use and shorten journey times. On some ferry and water taxi services, landings operate on request. In remote air services, especially in regions with dispersed communities, pilots may land at airstrips only when notified or when passengers signal need.

Benefits and limitations

Benefits include reduced travel time for through passengers, lower fuel consumption and the ability to serve dispersed communities without building full stations. Limitations include potential confusion for unfamiliar travelers, accessibility challenges for people who cannot easily signal, and the need for clear timetable information. Modern operators reduce these issues with signage, announcements, and electronic booking or onboard notification systems.

History and cultural note

The practice dates to early coach and railway services when passengers would literally flag vehicles to stop. In political campaigning, the phrase "whistle stop" came to describe brief public appearances from a train platform. The request-stop model remains a practical compromise between coverage and efficiency on lower-demand routes, adapting to new technology and scheduling methods while retaining traditional signalling in many areas.
