Trainee Train Driver Training: What Happens After You're Hired (and the Licence You Earn)

Two documents, not one: the licence and the certificate

Driving trains on Britain's mainline railway requires both a train driving licence and a train driving certificate. They do different jobs, and understanding the difference explains much of how training is organised.

The licence is issued by the ORR. It shows that you meet the medical, educational and general professional requirements to drive trains. The ORR states that it is valid for 10 years, is your personal property, and stays valid if you move to a different train operator. You cannot apply for it yourself: the ORR only issues a licence on an application made by a train operator or infrastructure manager — in practice, your employer applies once you have completed the required training and examinations.

The certificate is issued by your employer. It lists the specific rolling stock (traction) and the routes you are competent to drive. It belongs to the operator, not to you. Under regulation 16 of the 2010 Regulations, it stops being valid when you leave that employer, although the employer must give you a certified copy and records of your training, qualifications and experience.

The licence requirement applies to the mainline network. The ORR notes that it is not needed to drive on heritage railways, metros such as London Underground, tramways, in depots or in engineering possessions — which is why Tube drivers follow a separate route, covered in our How to Become a Tube Driver guide.

Who is eligible for a licence

Regulation 8 of the 2010 Regulations sets the baseline. An applicant must be at least 18 and must have completed at least nine years of primary and secondary education. They must also pass the medical and occupational psychological examinations set out in Schedule 1, and an examination of the general professional knowledge set out in Schedule 3.

The minimum age dropped from 20 to 18 on 30 June 2026, when the Train Driving Licences and Certificates (Amendment) Regulations 2026 (S.I. 2026/461) came into force. In its consultation response the government was explicit that younger applicants go through the same selection and assessment process as everyone else. Individual operators still set their own entry requirements in each advert, so check the vacancy rather than assuming every operator now recruits at 18.

Phase 1: classroom theory and the rule book

Training starts in the classroom. The Department for Transport's description of driver training lists the theoretical content operators cover: traction and braking systems, recognising signalling and signage, working in degraded conditions such as extreme weather, identifying hazards, speed limits and risks, operating different rolling stock, dispatching passengers safely, and responding to emergencies. It also covers professional topics: shift work, stress management, maintaining concentration and keeping up with new technology and procedures.

Schedule 3 of the Regulations sets out the general knowledge every licence holder must have. It includes the legislation and rules for rail safety, the demands of working mainly alone on shifts across a 24-hour cycle, behaviour compatible with safety-critical work (medication, alcohol, drugs, illness, stress and fatigue), and using reference documents such as the rule book, route book and driver's manual.

This phase is heavy on reading and recall. You are expected to learn rules precisely and apply them correctly later, often when something has gone wrong. That is the same ability the TRP1 rules test probes at selection: read a set of procedures, retain them, and answer accurately from memory.

• ✓Expect regular knowledge checks rather than one exam at the end — trainees are assessed as they go.
• ✓Build a study routine early. Short daily revision of rules beats cramming before an assessment.
• ✓Ask instructors for the reason behind each rule. Rules you understand are much easier to recall under pressure.

Phase 2: traction training on your trains

Traction training teaches you the specific units or locomotives your depot operates. Schedule 5 of the Regulations sets out what a driver must be able to do after rolling stock training: carry out the checks and tests before departure, know every control and indicator (particularly traction, braking and safety systems), detect and report faults, and know what to do when the train fails or in an emergency, including protecting the train and evacuating passengers.

This is where mechanical understanding helps. You do not need an engineering background, but you will need to follow how air brakes, power supply and safety systems behave, and to diagnose faults using a fault-finding guide while the clock runs.

Phase 3: route learning

Route knowledge is what separates train driving from most other jobs. Schedule 4 lists what a driver must know about each line: speed limits for the train types driven, the signalling system and block regulations, station and signal box positions and how to sight them, gradients and topography, changes between power supply systems, and the alternative routes agreed for diversions.

Schedule 7 says the favoured method is for the trainee to accompany another driver for an appropriate number of journeys over the route, in daylight and at night, and it allows cab-view videos as an additional method. In practice route learning often takes months at a busy depot with a large route card, and you sign for each route only when you and your assessor are satisfied you know it.

Trainees who do well here tend to treat it as active study: annotating route maps, noting braking points and signal positions, and testing themselves before each trip rather than watching the line go by.

Phase 4: supervised driving

The final stage is practical handling. The Department for Transport describes trainees driving live trains under the supervision of an instructor, developing their ability to handle driving tasks including responding to different scenarios such as emergencies. Schedule 7 adds that training should balance classroom and practical work, and that simulators — while not compulsory — are particularly useful for abnormal conditions and rarely used rules.

Operators decide how many supervised hours and assessed runs a trainee needs before signing them off, and this is not published as a single national figure. Expect a final practical assessment over your routes before you are allowed to drive on your own.

How long training takes

The Department for Transport states that driver training typically takes 9 to 24 months depending on the size and nature of operations at the depot, that there is no set time limit, and that the average driver takes well over a year to become fully qualified. A small depot with one type of train and a short route card sits at the faster end; a large depot with several traction types and an extensive network takes longer.

Plan your finances for this period. Trainee pay is lower than qualified driver pay at most operators, and the step up comes when you qualify — our train driver salary guide covers the typical figures. Ask at interview what the trainee rate is, how long training usually takes at that depot, and whether the contract includes any repayment of training costs if you leave early.

Staying qualified: the checks never stop

Qualifying is not the end of assessment. The 2010 Regulations build in periodic checks for the whole of your career.

• ✓Medical examinations at least every three years up to age 55, then every year (Schedule 1). A recognised doctor can require more frequent checks, and one may be carried out after 30 days or more of sick leave.
• ✓Infrastructure (route) knowledge checked at least every three years, or after any absence of more than a year from the route (Schedule 6).
• ✓Rolling stock knowledge checked at least every three years (Schedule 6).
• ✓The licence itself lasts 10 years before renewal, and the ORR can suspend or withdraw it.
• ✓Operators also monitor driving performance day to day, including through on-train data recorders.

How the selection tests connect to training

Schedule 1 says the occupational psychological examination must check that a driver has no established deficiencies in operational aptitudes or relevant personality factors likely to interfere with safe working. The Department for Transport explains that the detailed psychological requirements are set in the Rail Industry Standard RIS-3751-TOM, and the medical and psycho-motor requirements (reaction time, balance and coordination) in RIS-3789-TOM.

That is why the selection battery looks the way it does. Sustained concentration (the vigilance test), visual attention (the ATAVT and Group Bourdon), and rule retention (TRP1) map directly onto the training you have just read about: hours of monotonous running where you must stay alert, constant scanning for signals and hazards, and a rule book you must know cold. Operators are using selection to predict who will get through 9 to 24 months of training and stay safe afterwards.

Practising those abilities before your assessment is the sensible first step. Our practice tests are original exercises built around the same abilities — they are not the official tests — and the free demo includes a shortened vigilance test, ATAVT scenes and a TRP1 taster.
