South Western Railway guard assessment

London Waterloo to Hampshire, Dorset, Surrey, Wiltshire and the Isle of Wight connections

South Western Railway runs two guard grades — Commercial Guard and Metro Guard — and assesses in person on an assessment day rather than through a purely online battery.

South Western Railway publishes its four stages plainly, and the wording of the assessment stage is unusually direct: safety-critical tests measuring concentration, rule-following and awareness. The interview that follows is structured, with competency, specialist and hypothetical questions. Vision testing, including colour vision, sits at the medical at the end — not, as older applicant accounts describe, at the start of the day.

What to practise for South Western Railway

Matched to the stages above. Every demo is free and needs no account.

What we do not cover

  • A concentration test — timed sheets of symbols to scan and mark — is part of this process and is not practised on this site.

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.
