The Tube Driver
Test
Becoming a London Underground Train Operator is one of the best-paid driving jobs in the UK — and one of the most competitive. Selection is not one test but a sequence: an online SJT, then cognitive and psychomotor tests at an assessment centre. Here is every test you will face, what each one measures, and how to prepare.
What is the Tube driver test?
When people search for the "Tube driver test", they are really describing the whole London Underground Train Operator selection process — not a single exam. It typically starts with an online Situational Judgement Test, and candidates who progress are invited to an assessment centre where a set of cognitive and psychomotor tests is administered under standardised conditions, alongside a structured interview and a medical.
Several of these assessments come from the same family of psychometric tests used across the UK rail industry — which is why you will see names like the Vigilance Test (WAFV), the ATAVT, the TRP1 and the Group Bourdon. The exact mix can vary between recruitment campaigns, but the underlying abilities measured — sustained attention, perceptual speed, concentration, rule retention and sound judgement — are consistent. Below is every test you are likely to meet, with a full breakdown and practice for each.
The assessments
Every test, explained
Situational Judgement Test (SJT)
Judgement & safetyThe core online assessment every London Underground applicant takes. Workplace scenarios with response options to rank or choose. Measures whether your decision-making aligns with a safe, customer-focused, procedure-following Train Operator.
Full guide & practice →Vigilance Test (WAFV)
Sustained attentionA 30-minute test of your ability to stay alert on a long, uneventful task. A stimulus changes at random intervals and you respond the instant it does. It mirrors the concentration needed driving repetitive Underground sections, shift after shift.
Full guide & practice →ATAVT (Perception)
Perceptual speedA scene flashes for around one second; you identify which elements were present. Tests how quickly and accurately you take in a complex visual scene — the rapid scene-reading a driver does approaching platforms and signals.
Full guide & practice →TRP1 (Rules & Procedures)
Rule retentionYou read a set of fictional operating rules for a few minutes, then answer questions from memory. Measures how well you absorb, retain and apply procedural information under pressure — central to safe operation on the Underground.
Full guide & practice →Group Bourdon
ConcentrationA concentration task: scan rows of dot groups and mark every group containing exactly four dots. Measures accurate, systematic working sustained over time without losing focus.
Full guide & practice →London Underground's process shares much of its cognitive battery with mainline train driver selection — see the full train driver aptitude test guide for the wider set of tests, including SCAAT, TEA-OCC and 2-hand coordination.
The London Underground selection process
London Underground recruits Train Operators directly, usually in batches rather than continuously, so campaigns open and close quickly and attract very large numbers of applicants. After your online application, the first hurdle is normally the Situational Judgement Test, completed at home and often monitored. Clearing it earns an invitation to an assessment centre.
At the centre, the cognitive and psychomotor tests are usually completed in a single session alongside a structured interview. Most tests are computer-based and timed; the longest single component is the 30-minute Vigilance Test, which many candidates find the most demanding simply because of how long you must hold your concentration. A medical and reference checks follow a successful assessment day. No prior rail experience is needed — everything is taught during paid training.
How to prepare
A practical plan
Take the SJT seriously
The Situational Judgement Test is the first filter and quietly screens out a lot of candidates. Practise scenario-based questions and let safety, clear communication and following procedure guide your answers — that is the profile London Underground is selecting for.
Practise the full battery, not just one test
Assessors build a cognitive profile from your whole performance. Spreading practice across Vigilance, ATAVT, TRP1 and Group Bourdon protects you from a single weak test dragging down the overall picture.
Build Vigilance stamina early
Thirty minutes of unbroken concentration is the hardest single demand. Start practising the Vigilance Test weeks in advance and build up — leaving it to the last few days is the most common preparation mistake.
Train accuracy before speed
Across the concentration and perception tests, errors hurt you more than a slightly lower volume. Get the rule right consistently first; speed follows naturally as recognition becomes automatic.
Simulate real conditions
Sit timed, full-length runs in a quiet room without interruptions. Familiarity with the format and timing removes a major source of assessment-day anxiety so you can focus entirely on performance.
FAQ
Common questions about the Tube driver test
What is the Tube driver test?
There is no single 'Tube driver test' — London Underground Train Operator selection uses a sequence of assessments. It usually begins with an online Situational Judgement Test (SJT), and shortlisted candidates are invited to an assessment centre that includes cognitive and psychomotor tests such as the Vigilance Test (WAFV), the ATAVT, the TRP1 rules-and-procedures test and the Group Bourdon concentration test, alongside a structured interview and a medical. The exact combination can change between recruitment campaigns.
How much does a London Underground Tube driver earn?
Tube driver (Train Operator) base pay is around £71,000 a year as of 2026, with overtime and shift allowances commonly taking total earnings into the £70,000–£80,000 range. The package also includes a strong pension, generous annual leave and travel benefits. It is one of the best-paid driving roles in the UK — always check the current vacancy for confirmed figures.
How do I become a Tube driver?
London Underground recruits Train Operators directly, usually in batches rather than continuously. You apply online when a campaign opens, complete the SJT and any online ability tests, then — if shortlisted — attend an assessment centre for the cognitive and psychomotor tests and an interview, followed by a medical. No prior driving or rail experience is required; all traction and route knowledge is taught during paid training. Competition is intense, with very large numbers of applicants per campaign.
How hard is the London Underground selection process?
It is competitive and the cognitive tests catch many candidates out — particularly the 30-minute Vigilance Test, which demands sustained, unbroken concentration. The tests are not academically difficult, but holding accuracy and focus across the full set is genuinely demanding. Candidates who practise the format in advance consistently outperform those who arrive cold.
Can you practise for the Tube driver tests?
Yes, and you should. You cannot revise facts for an aptitude test, but the abilities measured — sustained attention, perceptual speed, concentration, rule retention and judgement — all improve with practice. Sitting realistic, timed versions of each test builds both the skill and the familiarity that reduce assessment-day nerves and lift your performance.
Are these the official London Underground tests?
No. These are independent practice tests modelled on the format and parameters of the assessments used in Train Operator selection. We are not affiliated with Transport for London or London Underground, and no practice site can replicate the exact proprietary software — but the format and timing are calibrated to be similar so nothing surprises you on the day.
