Under route signalling, a driver is informed which route the train will take beyond each signal (unless only one route is possible). This is achieved by a route indicator attached to the signal. The driver uses their route knowledge, reinforced by speed restriction signs fixed at the lineside, to drive the train at the correct speed for the ...
Signalling in the UK uses route signalling. Most railway systems around the world, however, use speed signalling. Under route signalling, the driver is informed which route has been set by an illuminated Junction Indicator mounted on the signal post. The signal will display a restrictive aspect to make the driver reduce the train's speed. Once ...
There are two main types of signaling aspect systems found in North America, speed signaling and weak route signaling. [citation needed] Speed signaling transmits information regarding how fast the train is permitted to be going in the upcoming segment of track; weak route signaling transmits information related to the route a train will be taking through a junction, and it is incumbent upon ...
The US and Canada departed from UK practice wherein a semaphore blade is devoted to each route (Route Signaling). General North American practice is to group routes by speeds and use a single blade for, say, "medium speed" regardless of the number of routes involved (Speed Signaling). The primary exception to this situation is in the field of ...
A railway signal is a visual display device that conveys instructions or provides warning of ... At that specific station the selected route ends on a stub track ...
Once a route is set and a train is given a signal to proceed over that route, all switches and other movable appliances in the route are locked in position until either the train passes out of the portion of the route affected, or; the signal to proceed is withdrawn and sufficient time has passed to ensure that a train approaching that route ...
A Thameslink service calling at the airport was delayed by nearly two hours. Rail services are expected to be disrupted for the rest of Wednesday due to the fault between London St Pancras and St ...
On a rail transport system, signalling control is the process by which control is exercised over train movements by way of railway signals and block systems to ensure that trains operate safely, over the correct route and to the proper timetable.
