Practice for the exercises applicants report in the Network Rail signaller assessment

No railway experience needed, training provided, and far more applicants than places — so the online assessment does a lot of the filtering. It is not verbal and numerical reasoning. It is doing three things at once, checking figures at speed, and judgement calls where the safe answer is not the obvious one.

See each exercise, then try it

Every one of the five has a free playable demo — our full exercise, not a screenshot. Nothing here is behind a sign-up.

Multi-tasking

Three things at once: arithmetic, a shape stream to watch for repeats, and something to steer.

Try it free →

Concentration

Decide fast and repeatedly whether a figure meets the rule — and spot the one that does not.

Try it free →

Job simulation

“Day in the life” scenarios: what a signaller does first when something goes wrong.

Try it free →

Memory grid

Hold a sequence of dot positions in order while something else keeps interrupting you.

Try it free →

Questionnaire briefing

A multiple-choice briefing on the agree/disagree questionnaire: which skill each statement reads, and which answers contradict each other. Not a copy of the questionnaire itself.

And all five in one sitting

The full run puts them back to back with no break, which is the part preparing section by section never reproduces.

Also recruiting: crossing keepers

Applying to be a Network Rail crossing keeper?

Crossing keepers go through their own Network Rail online tests. Applicants have reported a risk and safety questionnaire and concentration and reaction tests. Our crossing keeper practice has the matching exercises plus 125 level crossing scenarios with the reasoning written out.

How the process runs

Signaller recruitment on Britain's main rail network is run by Network Rail. Its recruitment journey page sets out seven stages, from an eligibility check and two rounds of online assessments to a video interview, an assessment day and a conditional offer, and its FAQs are worth reading first. It does not publish the exercises in its online assessments; the detail below is the shape applicants have described between 2024 and 2026, and it can vary by role and round.

Online assessments

Sat at home and remotely invigilated. Applicants report four exercises: multi-tasking, pattern checking, a job simulation and a behaviour questionnaire. Some grades also get a memory grid.

Video interview

Around five competency questions. You watch the prompt and record your answer, with a second take available on each.

Assessment day

Network Rail describes an interview and simulated activities relevant to signalling. Applicants have reported a short presentation and a competency interview of up to an hour built on non-technical skills.

Full assessment bundle

One payment, yours for good

All five exercises unlimited, the full run that chains them together, and a worked explanation behind every scenario. No subscription and no 30-day window — access does not expire.

One payment · lifetime access · 14-day money-back guarantee

✓The multi-tasking exercise — Three tasks at once for three minutes, scored separately so you can see which one you drop
✓Pattern checking — 274 timed items on holding a standard steady, not on being clever
✓150 job-simulation scenarios — Every one with the reasoning written out, not just a key
✓The memory grid — Adaptive sequences with the interruption dialled up or down
✓The questionnaire briefing — A multiple-choice drill on the skills the questionnaire reads, not a copy of it
✓The whole thing end to end — All five sections back to back, which is where people actually come unstuck

Why this and not general aptitude practice

Generic aptitude practice is a different test

Search for signaller practice and you are often pointed at SHL verbal and numerical reasoning, or at train driver material. Neither is what signaller applicants describe sitting.

The hard part is divided attention

Every exercise in the battery is easy taken on its own. What is being measured is what happens to your accuracy when something else is also demanding it.

You cannot revise judgement, but you can calibrate it

The scenarios have a consistent logic — deal with the danger first, confirm rather than assume, own the mistake, and do not over-react when it is not a danger. A hundred and fifty of them is enough to make it automatic.

Guides to each stage

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.
