Railway Signaler
Manages train movements across rail networks — ensuring trains don't collide and schedules run smoothly.
Did you know?
Swiss trains run on a 'clock-face' timetable: journeys between big hubs take multiples of 15 minutes, so trains meet at stations together.
How subjects help
- Mathematics: Space trains out along the line so each one has a safe stretch of empty track ahead.
- Computer Science: Operate the control screens that switch points and set signals across a rail network.
- Engineering: Understand how the track senses a train so you can act quickly when a signal fails.
- Communication: Talk a driver through a problem over the radio, such as passing a broken signal safely.
A famous name
John Saxby: Called the 'father of modern signalling'; patented interlocking of railway points and signals in 1856.
Try it yourself: Keep two trains safely apart
- Only one train may be on a single-track section at a time. Draw the line and the loop.
- What is the earliest Train 2 can leave C without ever meeting Train 1 on a single track?
- Write a timetable for both trains.
- Train 1 is 5 minutes late. What must change?
Railway signallers and train drivers work to exact timetables and signals so trains share tracks without ever meeting head-on.
