Checked 25 October 2026. Updated for RIS-3751-TOM issue 4 (in force from 7 December 2024). Rules are from the Train Driving Licences and Certificates Regulations 2010, ORR's guide of 9 April 2026 and RSSB's December 2024 FAQ; support and research from RSSB's "Driving inclusion" report, The OPC, Translink, The Train Drivers Academy and GOV.UK, read 25 Oct 2026. This page is not medical or legal advice; the train company and its recognised doctor decide your case.
No official rule we read bars ADHD or dyslexia by name. Great Britain's train driving regulations test effects instead: a driver must not have a condition, or take medication, likely to reduce attention or concentration. A recognised doctor judges that at the medical, and you can ask for adjustments to the psychometric tests.

The short answer, from the rules themselves
This page is about Great Britain's mainline railway, where anyone employed to drive a train needs a licence from the Office of Rail and Road (ORR). To get one, ORR says, a driver must pass both a medical examination and an occupational psychological fitness examination before appointment. Northern Ireland has its own: Translink, the Northern Ireland Transport Holding Company's group, says its train driver assessment process complies with the Train Driver Licences and Certificates Regulations (TDLCR) (NI) 2010. Translink's policy is quoted below where it differs.
| Question | What the official documents say | Source |
|---|---|---|
| Is ADHD or dyslexia a bar by name? | None of the documents we read names either one as a bar: not the regulations' medical schedule, not ORR's guide, not RSSB's FAQ, The OPC's guide or Translink's policy. | TDLCR Schedule 1; ORR guide; RSSB 3751-FAQ; The OPC; Translink HR023 |
| What does the medical rule test? | Effects. A driver must not have a medical condition, or be taking any medication, drugs or substances, likely to cause any of five things, one of them "a reduction in attention or concentration". | TDLCR Schedule 1, paragraph 1(1); ORR guide, paragraph 2.8 |
| Does a health condition mean you fail the medical? | "Having a health condition does not automatically mean you will not pass, but it may need to be reviewed in more detail." | The Train Drivers Academy |
| Who decides? | Medical examinations must be conducted or supervised by doctors on ORR's register of recognised doctors, and doctors or medical assessors should consider the five restrictions during the general medical examination. | ORR guide, paragraphs 2.8 and 2.14 |
| Can the psychometric tests be adjusted? | Yes, you can ask: RSSB says candidates with a disability or condition, "including neurodiversity", can ask for suitable adjustments. Evidence will be required. | RSSB 3751-FAQ, question 15 |
| Do neurodivergent people drive trains? | Yes. RSSB's "Driving inclusion" report is based on interviews with eight neurodivergent train drivers, and names ADHD and dyslexia among the conditions neurodiversity covers. | RSSB, "Driving inclusion" report |
Two answers that are too simple
- "A diagnosis rules you out." Not in any document we read. The medical rule is about likely effects, judged person by person.
- "A diagnosis never matters." Also not what the rules say. A condition or a medicine likely to reduce attention or concentration is exactly what the medical rule is about, so it may be reviewed in more detail. Attention is also the first selection criterion in the psychometric standard.
Our summary of the official documents above.
What the medical checks, in the regulations' own words
Schedule 1 of the Train Driving Licences and Certificates Regulations 2010 sets the medical requirements. Its general requirement reads: "Drivers must not be suffering from any medical conditions or be taking any medication, drugs or substances which are likely to cause—"
The five effects in Schedule 1, paragraph 1(1)
- a sudden loss of consciousness
- a reduction in attention or concentration
- sudden incapacity
- a loss of balance or coordination
- significant limitation of mobility
Quoted from TDLCR 2010, Schedule 1. ORR's guide (paragraph 2.8) repeats the list and says doctors or medical assessors should consider these restrictions when carrying out the general medical examination.
The minimum content of the medical before appointment includes, among other things, "tests for psychotropic substances such as illicit drugs or psychotropic medication and the abuse of alcohol calling into question the fitness for the job", and "cognitive: attention and concentration; memory; perception; reasoning" (Schedule 1, paragraph 2(1)). Medicals then recur: at least every three years up to the age of 55, every year after that.
Two things the documents do not tell you. No source we read lists which medicines a recognised doctor accepts, so we do not either. ORR names RSSB's RIS-3789-TOM, "Train Drivers – Medical Fitness Assessments", as industry good practice for the medical; we could not read its contents, so we quote none of it.
Which tests assess attention and vigilance
In RSSB's standard, each psychometric test assesses a selection criterion. Attention comes first in RSSB's table, with two tests, and a third test, the WAFV, assesses vigilance. The publishers of TEA-Occ and the WAFV both say their test measures sustained attention:
| Test | What it assesses (official) | Format | Publisher or official detail |
|---|---|---|---|
| Group Bourdon | Attention | Paper and pencil | No official source we read publishes its layout or timing. |
| TEA-Occ | Attention | Paper and pencil | TalentLens (its page): sensitive to selective attention, sustained attention and attentional switching; subtests include counting tones while ignoring other tones, and searching a mock telephone directory. |
| WAFV (vigilance test) | Vigilance; reaction time | Computerised | Schuhfried: measures vigilance and sustained attention; 18 to 32 minutes depending on the test form. |
| TRP1 and TRP2 | Memory; reasoning (Trainability for Rules and Procedures) | Paper and pencil | RSSB lists TRP1 under memory and TRP2 under reasoning. The OPC says the tests on the day look at, among other things, your ability to recall and retain job related information and learn new information. |
Criteria are from RSSB's FAQ (table 1) and formats from Translink's policy (Appendix B). The other tests (ATAVT perception, two-hand coordination, the situational judgement exercise and the interview) are in our guide to every train driver psychometric test, and TEA-Occ has its own guide.
Our reading, not an official statement: if your difficulty is holding attention over time, the Group Bourdon, TEA-Occ and the WAFV are the tests to practise for and ask about. If it is reading speed or accuracy, the TRP tests, which by their name assess trainability for rules and procedures, are where to ask whether an adjustment such as extra reading time is possible. RSSB's report notes that neurodivergent people "[m]ay experience periods of hyperfocus or (conversely) difficulty sustaining attention on tasks": the same person can find one test easy and another hard.
Practise the attention tests
Find out whether your accuracy drops late in a run
The result screen of our trainer compares your accuracy on the first half of the sheets with the second half, when both have reached groups (on an odd number of sheets the middle one is left out), and counts your missed and wrong marks apart. Level 1 is free, with no sign-in. It is attention practice, not a copy of any official test.

Medication and the medical: what to disclose, and what to ask your GP
There are four points in the process where your condition or your medication may come up. The documents give different people a role at each one:
When you apply, or as soon as you are invited to assess
Who: The train company's recruitment team
If you want adjustments at the assessment centre. Ask early: without prior notice support is not guaranteed and the assessment might be rescheduled. Evidence of your disability or condition will be required.
Source: RSSB 3751-FAQ, question 15; The OPC; Translink asks you to note it on the application form
Before you sit the tests
Who: The company or assessment centre
If you are unwell or something may affect your performance. Translink asks every candidate to sign a declaration that they are fit to sit: sitting certifies that you are fit and well, and waives any right to contest this later. If circumstances arise during the session you may be advised to leave and attempt the rest later, and mitigating-circumstances claims must reach Translink within 2 weeks.
Source: Translink HR023, section 11.1
At the pre-appointment medical
Who: The ORR-recognised doctor or medical assessor
The medical may look at general health, medical history, drug and alcohol standards and mental health. The minimum content includes tests for psychotropic substances, including psychotropic medication.
Source: The Train Drivers Academy; TDLCR Schedule 1, paragraph 2
Once you are a driver
Who: Your employer
A driver who considers that their state of health calls into question their fitness to drive must inform the employer immediately. A change of medication may trigger a medical referral.
Source: TDLCR regulation 17(3); ORR guide, paragraph 2.10
ProSyllabus summary of the documents named under each step, for Great Britain's mainline railway (step 2 is Translink's own policy). Your train company tells you its own process.
On the medical itself, The Train Drivers Academy says it "may look at eyesight, hearing, general health, medical history, drug and alcohol standards and mental health". The medical decision rests with an ORR-recognised doctor. ORR's guide says that if a recognised doctor thinks a driver should seek their GP's advice on matters beyond the scope of the medical, the reasoning should be clearly explained to the driver.
Questions to take to your GP or prescriber, before the medical
- Could my condition, or any medicine I take, be likely to cause any of the five effects the regulations list: a sudden loss of consciousness, a reduction in attention or concentration, sudden incapacity, a loss of balance or coordination, or significant limitation of mobility?
- Can I have a copy of my diagnosis, or a letter confirming it? The train company asks for evidence before it considers adjustments to the tests, and The OPC says the evidence typically outlines the adjustments recommended for you.
- What is the name and dose of each medicine I take, so I can give the recognised doctor an accurate list?
- If my medicine or dose changes after I qualify, what should I tell my employer? (ORR says a change of medication may trigger a medical referral.)
Our list of questions, not medical advice. The decision on fitness to drive trains rests with an ORR-recognised doctor at the medical. Do not stop or change a medicine for an assessment or a medical without speaking to whoever prescribes it.
Our advice: give the recognised doctor a complete and accurate account of your diagnosis and every medicine you take. A medical that later turns out to be based on missing information helps nobody, and once you are a driver the duty to report a health concern is written into regulation 17(3).
Reasonable adjustments: what is known, and who to ask
RSSB's FAQ, question 15: "If you have a disability or condition, including neurodiversity, or may need adjustments to be made at the assessment centre, you can ask for suitable adjustments." It tells you to contact the train company's recruitment team as soon as possible, warns that "Without prior notice, support is not guaranteed, and your assessment might have to be rescheduled", and adds that evidence of your disability or condition will be required.
| Point | What the sources say | Source |
|---|---|---|
| Who to ask | The organisation you applied to (The OPC); the train company's recruitment team, as soon as possible (RSSB). | The OPC; RSSB 3751-FAQ, question 15 |
| When | As early as possible, before the test date. Translink: adjustments cannot be requested or agreed on the day of the assessment, and should be noted on the application form. | RSSB; Translink HR023, reasonable adjustments and section 11.2 |
| Evidence | Required (RSSB). The OPC: the company will ask for evidence of your diagnosis, as it typically outlines the adjustments recommended for you. | RSSB 3751-FAQ, question 15; The OPC |
| What adjustments can look like | Translink: modifications to test format, additional time allowances or alternative testing arrangements, reviewed with its external test supplier. No source we read says which adjustment applies to which test. | Translink HR023, section 11.2 |
| Neurodiversity and disability | Translink treats an applicant who highlights a "neurodiverse condition" as meeting the definition of disability in the Disability Discrimination Act 1995 (as amended). | Translink HR023, reasonable adjustments |
The law behind this, in Great Britain, is the Equality Act 2010. GOV.UK says you are disabled under it if you have a physical or mental impairment with a "substantial" and "long-term" negative effect on your ability to do normal daily activities, and that employers must make reasonable adjustments, including "changing the recruitment process so a candidate can be considered for a job"; and GOV.UK's guidance for employers gives the example of allowing candidates to complete a written test using a computer. RSSB's report adds that a formal diagnosis is not required for a person to be considered disabled under the Act. That is the legal definition; at the assessment centre, RSSB says, adjustments still need evidence.
Two limits are written down too. GOV.UK says some jobs may have an essential requirement that cannot be met with a reasonable adjustment, and the medical requirements in Schedule 1 apply to every driver. Some companies also run disability schemes: Southeastern's trainee driver advert (closing date 1 January 2026) says that, as a member of the Disability Confident scheme, it will offer an interview to applicants who apply under the scheme and meet the minimum criteria.
Help with the cost of support at work comes from Access to Work (England, Scotland and Wales; Northern Ireland has a different system). GOV.UK lists "having ADHD or dyslexia" among the conditions it can cover and says you do not need a diagnosis to apply. It can also help pay for communication support at a job interview, under its own eligibility rules.
What neurodivergent drivers told RSSB
RSSB's report "Driving inclusion" (its page is dated 19 March 2026) is based on interviews with eight neurodivergent train drivers and three workshops with employer representatives. Many drivers described the cab as a place that suits their strengths: fixed timetables, clear rules, largely solitary work. The strengths they named include focus, attention to detail and route learning. The challenges included reading rotas and dense written material, and fear of disclosing. One driver said: "I was too scared to say anything in case it costs me my job."
The report's ideas for employers include clear processes for adjustments, and, for learning and competence assessments, options such as "Consider removing exam time limits, if time is not part of the criteria being assessed". These are suggestions for training and workplace assessments, not rules for the selection tests. RSSB's Right Track gives one example in practice: a GB Railfreight train manager with autism said that during his driver examinations a manager can reword questions and he can answer orally instead of writing. In September 2026 RSSB also published a tender for research into neuroinclusive principles for driver training, development, competence management and related workplace activities, while maintaining safety-critical competence requirements.
How to prepare: a plan that does not depend on luck
| Step | What to do |
|---|---|
| 1. Before you apply | Gather the evidence of your diagnosis and, if you take medicine, the name and dose of each one. Take the questions above to your GP or prescriber. |
| 2. When you apply | Tell the company's recruitment team, early and in writing, if you want adjustments, and ask what evidence it needs. Translink asks for it on the application form. |
| 3. When the practice materials arrive | The OPC says you should receive them at least 7 days before the assessment day, from the organisation you applied to. Work through them early, and note anything that would make an adjustment worth asking for. |
| 4. In the weeks before | Short, regular attention sessions rather than long ones, at the time of day of your assessment. Track your own accuracy run by run. |
| 5. On the day | If you are unwell, or something may affect your performance, tell the company before you sit: Translink asks candidates about mitigating circumstances before the assessment, and takes claims within 2 weeks of it. Attempts are limited: for candidates starting from 7 December 2024, three failed attempts end the process, with long waits between them. |
Steps 1 and 4, and "in writing" in step 2, are ProSyllabus advice; the rules in each step are from the sources named. The attempt rules, a date checker and a 12-month plan are in our guide to train driver retakes and pass rates, and the order of the day is in what happens on the assessment day.
Frequently asked questions
Can you be a train driver with ADHD?
No official document we read bars ADHD by name. The medical rule is that a driver must not have a condition, or take medication, likely to cause a reduction in attention or concentration (or four other effects). An ORR-recognised doctor judges that at the medical, and you can ask the train company for adjustments to the psychometric tests, with evidence.
Can you be a train driver with dyslexia?
No official document we read bars dyslexia. RSSB says candidates with a condition, including neurodiversity, can ask for suitable adjustments to the psychometric assessment, and evidence will be required. RSSB's "Driving inclusion" report on neurodivergent train drivers names dyslexia among the conditions it covers.
Do I have to tell the train company about my ADHD or dyslexia?
The documents we read do not say you must mention it on the application. If you want adjustments to the tests, contact the recruitment team as soon as possible; evidence will be required (RSSB), and Translink says adjustments cannot be requested on the day. The medical may look at your medical history and mental health and tests for psychotropic substances, including psychotropic medication, so answer its questions fully. Once you drive, regulation 17(3) requires you to tell your employer about a health concern that calls your fitness into question.
Will ADHD medication stop me becoming a train driver?
No source we read lists which medicines are accepted or refused. The test in the regulations is whether a medicine is likely to cause effects such as a reduction in attention or concentration, and the recognised doctor decides. Ask your prescriber, and do not change a medicine for the medical without speaking to them.
Can I get extra time on the Group Bourdon or the TRP tests?
Possibly. Translink says adjustments may include additional time allowances, but no source we read says which adjustments are given on which test. Ask the company you applied to, before the test date: Translink says adjustments cannot be requested or agreed on the day.
Do I need a formal diagnosis?
For adjustments at the assessment centre, RSSB says evidence of your disability or condition will be required, and The OPC says the company will ask for evidence of your diagnosis. Separately, RSSB's report notes that a formal diagnosis is not required to be considered disabled under the Equality Act 2010, and Access to Work does not require a diagnosis to apply.
Does this apply in Northern Ireland?
Not exactly. Translink's policy cites the Train Driver Licences and Certificates Regulations (NI) 2010, and GOV.UK says the Equality Act 2010 does not apply in Northern Ireland. Translink's policy treats a neurodiverse condition as meeting the Disability Discrimination Act 1995 definition of disability and sets its own adjustment rules.
