Network Rail signaller assessment practice
Practice for the online assessment Network Rail sends trainee signaller applicants 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.

What the signaller assessment is
After you apply, Network Rail sends trainee signaller applicants an online assessment. It is unsupervised and usually webcam-monitored, and it is not the verbal and numerical reasoning paper 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 experience is needed to apply. If you get through, initial training is around thirteen weeks, eleven of them in a classroom, and pay runs from roughly £36,000 at Grade 2 to around £59,000 at Grade 9 depending on the box. That combination — no entry requirements, good money, and a great many applicants per vacancy — is why the assessment does most of the filtering.
