Network Rail aptitude test: what you actually get sent

The short answer: there is no single "Network Rail aptitude test". What arrives in your inbox depends on the vacancy you applied for. Network Rail's own recruitment page — as last published, before it was removed in a site redesign — said applicants "may be asked to complete an assessment, which can consist of either a self-assessment, verbal, numerical or psychometric test". Trainee signaller applicants report something quite different from any of those: a battery of timed exercises built around multi-tasking, checking and judgement. So the first question to settle is not how to pass the test, but which test you are being sent.

Getting that wrong is the most expensive mistake in this whole process, because it is invisible. You can prepare diligently for weeks on the wrong material and go in feeling ready.

What Network Rail itself says

Very little, and less than it used to. As of September 2026 the live careers pages on networkrail.co.uk describe the organisation and link to the recruitment portal, but do not set out a recruitment process or name any assessment. The page that did — "How we recruit" — has been removed and now redirects to the careers landing page. The last archived version said this about testing:

"To enable us to discover your potential, you may be asked to complete an assessment, which can consist of either a self-assessment, verbal, numerical or psychometric test."

Three things are worth taking from that, and it is worth being clear that it is an archived page rather than a current statement.

• "May be asked." Testing is not universal across Network Rail vacancies.
• "Either ... or." Different roles get different assessments. There is no house test.
• It is written for the whole organisation — engineers, analysts, project managers, apprentices, signallers. It is not a description of the signaller assessment.

The same page said that safety is asked about at interview, and that offers are conditional on Baseline Personnel Security Standard checks, a medical and a drug and alcohol test. The National Careers Service also lists the medical and the drug and alcohol screening as requirements for railway signallers.

Which assessment goes with which role

Trainee signaller

This is the role most people mean when they search for a Network Rail aptitude test, and it is the one where the generic answer is most wrong. Network Rail does not publish the contents of the signaller online assessment. Applicants describing it publicly between 2024 and 2026 report a consistent set of exercises: a multi-tasking exercise with three tasks running at once, a concentration or pattern-checking exercise against the clock, a long multiple-choice job simulation, and a work-related behaviour questionnaire, with a memory grid on some applications.

Those are reported formats, not published specification, and the details can change between recruitment rounds — but nobody describes sitting a verbal reasoning paper. The signaller assessment explained goes through each stage, and every exercise has a free playable demo on the signaller practice tests hub.

Apprenticeships and graduate schemes

Network Rail's early careers schemes run their own selection, typically with online stages before a final assessment centre. Network Rail does not publish what those online stages contain on its early careers pages, and we are not going to guess at it here; the invitation email is the only reliable description. The National Careers Service does set out the entry requirements for the rail apprenticeships that lead towards operator roles: usually some GCSEs including English and maths for an intermediate apprenticeship, and five GCSEs at grades 9 to 4 including English and maths for an advanced one.

Train driver — not Network Rail at all

A large share of searches for Network Rail aptitude tests are really about driving trains, and drivers are not employed by Network Rail. Network Rail runs the infrastructure — track, signalling, most large stations — while drivers work for the train operating companies. That distinction matters here because driver selection is the one part of the railway where the assessment has a statutory floor: the Train Driving Licences and Certificates Regulations 2010 require an occupational psychological assessment covering attention and concentration, memory, perception, reasoning, communication and self-control, alongside specified medical standards.

That regulation is why the named test batteries you see discussed online — the Group Bourdon, the TEA-Occ and the rest — belong to driver selection. They do not appear in signaller applicant reports. Signaller vs train driver compares the two routes properly.

Operational, maintenance and track roles

Anything that counts as safety critical work sits under Part 4 of the Railways and Other Guided Transport Systems (Safety) Regulations 2006, which the Office of Rail and Road enforces. Signalling and the operation of level crossing equipment are named safety critical tasks in those regulations. That regime governs competence and fitness once you are employed rather than the aptitude test at the door, but it explains the shape of everything around the test: the medical, the drug and alcohol screening, and the assessment you go through at the end of training rather than at the start.

Why the wrong practice keeps getting recommended

Search for a Network Rail aptitude test and most of what comes back is generic psychometric practice — verbal reasoning passages, numerical reasoning tables, abstract sequences — usually sold as a bundle covering hundreds of employers. It is not that those publishers are inventing things. It is that "verbal, numerical or psychometric" appeared on a Network Rail page for years, and a generic product can be sold against it without anyone establishing which roles it applies to.

For a signaller application specifically, the mismatch is severe. Practising verbal reasoning does not make you better at keeping three tasks alive at once, and it does not calibrate your judgement on a safety scenario where two of the four answers look sensible. Nine ways people lose the signaller assessment starts with exactly this.

Pass marks, pass rates and scores

Network Rail does not publish a pass mark, a pass rate or a scoring method for any of its assessments, and no figure of that kind on this site or any other is a fact you can rely on. If you are quoted a specific percentage, ask where it came from — the answer is almost always another prep site.

What can be said without inventing numbers is that signaller vacancies attract far more applicants than there are places, which is unsurprising for skilled, well-paid work that needs no railway experience and comes with paid training. A competitive shortlist does the same job as a high pass mark, and it means capable people are turned down every round. What to do after failing the signaller assessment covers the practical side of that, including how to ask the recruiter whether and when you can sit it again.

Conditions matter more than they should

Signaller applicants describe sitting the online assessment unsupervised, at home, inside a window of a few days, often with webcam monitoring. That hands you a set of variables nobody is going to control for you:

• When you sit it. Not at the end of a shift, and not at 10pm because the deadline is tomorrow.
• What you sit it on. A real keyboard and a screen you can see properly. Timed exercises punish an unfamiliar trackpad.
• Interruptions. One knock at the door during a three-minute multi-tasking exercise is the whole exercise.
• Doing it once, properly. Read the instructions for each exercise before it starts rather than in the first ten seconds of it running.

What to do next

Work out which role you are applying for, then prepare for that. For a trainee signaller post, that means the exercises applicants actually report, in the order they report sitting them. The one-week preparation plan sets out how to spread that over seven evenings, and the free practice questions give you a sense of the job simulation before you commit any time to it.

If you are applying for something else at Network Rail, prepare for verbal and numerical reasoning by all means — but read the invitation email first, because it will name what you have been sent.
