REQUEST STOP

In public transport, a 'request stop' or 'flag stop' describes a stopping point at which trains or buses stop only on an as-needed basis, that is, only if there are passengers to be picked up or dropped off. In this way, infrequently used stopping points can be served efficiently.

Rail Transport


In rail transport, a 'request stop' or 'flag stop' describes a station at which trains stop only on an as-needed basis, that is, only if there are passengers to be picked up or dropped off. At request stops for which there are no passengers to be dropped off, trains need only slow in the vicinity of the platform — or, in some cases, pass it at speed — instead of coming to a complete stop at an empty platform. In this way, lightly-used stations can remain open and be serviced efficiently, rather than be closed.
The methods by which trains are notified that there are passengers waiting to be picked up at a request stop vary by station and country:
United Kingdom

In the United Kingdom, most request stop stations require that the guard is informed by passengers wishing to stop at the station and that passengers waiting to catch the train merely make themselves clearly visible to the driver as the train approaches at a speed slow enough to stop if necessary. In some cases the station platform is observable by railway staff either near the station (e.g. in the signal box at Kidwelly railway station) or at the station itself. In these latter cases the staff may inform the driver in advance so that there is no need for the train to slow down unnecessarily when no passengers are waiting.
Austria

In Austria request stops sometimes feature an electronic signal indicator that is operated by the passengers themselves. If a passenger presses this indicator, a control on the platform changes the signals for the driver to inform them that the train should stop at this station. Because these signals are well before the station, trains are able to pass at speed if no passenger is waiting.

Bus Transport


In bus transport the term ''request stop'' is used in two ways:
#A fixed bus stop which is only serviced if passengers request it, in a manner similar to a train request stop.
#A section of the route where passengers can request the bus be stopped at any point.
United Kingdom

In urban areas, some bus stops are mandatory (i.e, the bus always stops there) and others are request stops. Passengers wishing to board the bus at a request stop do so by hailing it with an extended arm as it approaches (although this is becoming less common and bus drivers normally stop when they can see passengers waiting, even when not hailed). Passengers wishing to leave the bus indicate this by using the stop bell or buzzer. Outside of urban areas, it is common for almost all bus stops to be request stops.
Request stops and mandataory stops have different signs. In London, mandatory stops have the TfL roundel symbol in red on white while request stops have it in white on red, as well as the word "Request".
The second type of request stop is also used in the UK, although it is not very common. It is normally referred to as "Hail and Ride". Passengers signal the driver in the same way as for a fixed request stop anywhere along the route of the bus, regardless of whether there is a fixed stop.
Canada

The term ''request stop'' is used on Canadian bus networks to describe a stop to let off or pick up passengers that is not at a marked bus stop. Several Canadian bus operators offer this facility on evening and night buses to make users feel safer and more comfortable using the bus. The term 'night request stop' is sometimes used for this.
