Signaller assessment practice
Practice for the online assessment trainee signaller applicants in the UK are sent after the application form. It is not verbal and numerical reasoning — it is a battery of short, fast exercises on attention, memory and doing several things at once.
Multi-tasking
Three things at once: arithmetic, a shape stream to watch for repeats, and something to steer.

What the signaller assessment is
After you apply for a trainee signaller post — on the main rail network that means applying to Network Rail — you are sent online assessments. You sit them at home and Network Rail says they are remotely invigilated. Network Rail calls the first one a short reasoning assessment, but applicants do not describe the generic verbal and numerical papers that most aptitude-test preparation will sell you. Applicants consistently describe a battery of short, fast exercises: doing three things at once, checking figures against a rule at speed, working through workplace scenarios, and a questionnaire about how you prefer to work. Some grades also get a memory grid.
No railway experience is needed to apply, and training is provided and paid once you are offered a post. Every Network Rail signaller starts on Grade 2 pay (a Grade 2 trainee post was advertised from £36,196 in October 2026), and each advert states the grade and salary structure for that post. A secure, well-paid job with no railway entry requirement attracts a great many applicants, which is why the online assessment does so much of the filtering.
Network Rail's own signaller page covers the job, requirements, training and pay, its recruitment journey page sets out the seven stages, and its FAQs cover the online tests. Read both alongside anything here.

The pace shown is the pace our practice sections run at. Network Rail does not publish the contents or the timings of its assessment, so ours are our own settings, based on what applicants describe rather than an official specification — always follow the guidance sent with your own application.
Guides
Plain-English background on each exercise, the video interview, the assessment centre, and how signaller recruitment actually works.
These are original practice exercises written to reflect the assessment format described by recent Network Rail signaller applicants. Network Rail publishes the stages of its signaller recruitment but not the exercises in its online assessment, so treat the format as reported rather than official, and always follow the guidance sent with your own application. These are not the official exercises, and this site is not affiliated with or endorsed by Network Rail.
