Signaller
Signallers are responsible for management the safe movement of trains around the UK. There are about 6000 signallers who work in signal boxes and control rooms and they use around 40000 signals to control how every train moves around its set route. Signallers may also control the direction of trains by moving the railway ‘points’ which determine on which track a train runs.The signals display messages in simple form to tell the driver whether or not to proceed with their journey. The messages are given either through the use of lights, or through signal ‘arms’, which are put into particular positions depending on the message required. The messages are delivered through a range of systems, from semaphore (arms) or colour light signals which are controlled by lever, to electro push-button system panels, which can be operated more quickly and have the capacity for faster and larger amounts of work.
Signallers have to play close attention to the schedule of operations for the day, making sure that they are aware of all train movements planned. They then plan the required routes and get ready to liaise with other control rooms or signal boxes to ensure that trains can move safely from one area into the next. They also have to alert the next signal box along the route once a train has passed by, so that they know that the train is approaching.
Signallers can also have responsibility for operating level crossings; lowering barriers to ensure that trains can safely cross public highways.
The starting salary for a signaller who has completed all required training is approximately £20000. This can vary based on responsibilities and may rise with experience.
