Entry level signaller

Our entry level signaller roles are your start into a rewarding career at Network Rail. You’ll play an integral part in the safe movement of trains across our network; connecting people, businesses and communities. We’ll provide you with all the training you need to keep our passengers moving.

What will you do?

Your decisions make all the difference. As a signaller, you’ll take great care to make sure trains travel safely and efficiently along your part of the network.

And when things do go wrong, you’ll use your training, problem solving skills and quick thinking to get our passengers moving safely onwards to their destination.

Our signaller community takes great pride in putting our passengers first.

It’s not a job for everyone but if you make the grade then you can look forward to a rewarding and fulfilling career.

What is signalling?

Signalling is essentially a sophisticated traffic light system for the railway.

The complexities of moving trains around such a large network, keeping them safely apart, and allowing for their long stopping distances, means the signalling system is very complicated and comprises a great many parts.

The signals themselves are the lineside pieces of equipment that tell train drivers when it is safe to proceed and what route their train will take.

Watch the video to find out what signals do and how they play their part in the running of the railway.
