Northern conductor assessment
Towns and cities across the North of England
- Trainee Train Conductor
- Conductor
Northern is one of the largest recruiters of conductors in Britain, and its Trainee Conductor vacancies appear across the North of England throughout the year. Northern conductors are safety-critical staff — the grade covers dispatch and door duties, not just revenue.
Northern itself describes the stage after the application only as “some online assessments”. Applicant accounts fill that in consistently: a timed calculation test built around percentages and figures read off charts, and a verbal reasoning test where you decide whether a statement is true, false or cannot be said from the passage.
In order
The Northern selection stages
This is not an official Northern process description. Your invitation letter is the authority for your own.
- 01Online application with competency-style questions on the form itself
- 02Online assessments — applicant accounts describe a calculation test and a verbal reasoning test
- 03Interview with the Northern conductor management team, with a team exercise alongside it at some sittings
- 04Talent pool
- 05Safety-critical medical, including drug and alcohol screening
Detail
Worth knowing about Northern
- Northern is unusual among the operators covered here: nothing in Northern’s own material or in applicant accounts points to a rules test or a concentration test for the conductor grade. Note that the two-attempt limit in Northern’s careers FAQ applies to the driver psychometrics, not to this process.
- Northern requires you to live within a 45-minute peak-time commute of the depot without relying on public transport, and defective colour vision is a bar.
- How long the talent pool runs is not something Northern publishes. The nine-month figure that circulates comes from a single applicant post from 2021, so treat it as folklore rather than fact.
Practice
What to practise for Northern
Matched to the stages above. Every demo is free and needs no account.
Fares & Numeracy
Excess fares, change, percentages and timetable arithmetic — in your head, at pace.
Customer Service & Verbal Reasoning
Read a passenger-facing passage or scenario and answer precisely what it supports.
Situational Judgement
On-train situations with no perfect answer — judge what you would actually do.
Every process on this list ends in a competency interview. Our guide to the interview and the role play covers the competencies operators assess and how to structure an answer, and the process guide sets out every stage across the sector.
Before you apply elsewhere
Not every operator has an on-board grade
If you are comparing operators, these run driver-only services and have no conductor or guard job to apply for:
- c2c
- Driver-only operation on the London, Tilbury and Southend route. No conductor or guard grade.
- Elizabeth line
- Driver-only operation. The concession changed hands in May 2025 and is now run by GTS Rail Operations; its frontline grades are customer and revenue roles, not a conductor grade.
- London Overground
- Driver-only. The concession passed to First Rail London in May 2026, but the brand and the six named lines are unchanged, and the frontline grades are station and revenue roles.
- Heathrow Express
- Driver-only, and run by GWR under a management contract, so its train crew hiring goes through GWR rather than Heathrow Express itself.
- Thameslink and Great Northern
- No conductor or guard grade — these run driver-only. Both do advertise a Passenger Host grade, which is revenue, customer and security work without door or dispatch duties. Southern, in the same group, is different — see its page.
- Freight operators
- Freight trains have not carried guards since single-manning in the 1980s. Note the naming trap: GB Railfreight advertises “Train Manager” and “Trainee Train Manager” vacancies that are train driver roles, and asks for a driver psychometric pass within the last five years.
