The Train Driver
SJT Test
A workplace scenario appears on screen. You decide which response is most appropriate, and which is least. Here is exactly what the Situational Judgement Test measures, what assessors look for, and how to think about each scenario — plus five free practice scenarios to try right now.
Train Driver Tests is an independent practice platform. Our scenarios are original content modelled on the SJT format used in UK train driver online screening — they are not the official test, and we are not affiliated with any train operating company or test publisher.
What is the SJT?
The Situational Judgement Test (SJT) is a psychometric assessment used by most major UK train operating companies at the online screening stage of train driver recruitment. It presents you with realistic workplace scenarios — a defect spotted before a service, a conflicting radio instruction, a passenger emergency on a busy platform — and asks you to rank or pick the most and least appropriate way to respond.
Unlike a numerical or memory test, the SJT is not measuring whether you can compute or recall information. It is measuring your judgement — the values and instincts you would bring to the cab. Operators want to know that your default response under pressure is to escalate safety concerns, follow procedures, communicate precisely, and report your own mistakes honestly. The SJT screens out candidates whose instincts pull the other way before any expensive face-to-face assessment.
There are no trick questions. Every scenario has a model answer agreed in advance by subject-matter experts — usually current and former train drivers, recruiters, and safety specialists. Your score reflects how closely your judgement aligns with the model answer across the whole test.
What it measures
Six competencies tested in train driver SJTs
Safety culture
Holding firm on safety even under operational or commercial pressure
Rule compliance
Following procedures precisely, even when you personally disagree
Reporting honesty
Reporting your own errors and concerns promptly and factually
Communication
Clear, structured radio and verbal communication under pressure
Customer service
Treating passengers professionally without compromising your duty
Composure
Staying calm and methodical when scenarios escalate or change

Five-scenario SJT demo
Five realistic scenarios across the core competencies. Read each one, pick the most and least appropriate response, then reveal the answer with a detailed explanation of the underlying reasoning.
Scenario 1 of 5
0 / 5 completed
Safety vs. operational pressure
You are due to take a service out of the depot. During your pre-departure walk-round you notice a small but unfamiliar fluid leak under the leading cab. The shift controller radios to ask why you are delayed — they tell you the next service is already late and any further delay will affect the morning peak.
Tell the controller you will move the unit out and report the leak as a defect at the next stabling point, to avoid further delay to passengers.
Stop the walk-round there, drive the service as normal, and assume that maintenance will spot the issue at the next exam.
Tell the controller you have a defect that needs investigation before you can move the unit, and contact the fitter on duty.
Take a photo of the leak on your phone, then drive the service and email the photo to the depot manager when you finish your shift.
How to prepare
Step by step
Read the scenario fully before looking at the options
Resist the urge to scan the options first. The scenario sets the priorities — schedule pressure, a safety concern, a passenger need, a colleague issue — and you need that context to judge each option fairly.
Default to safety in any conflict
When two priorities pull against each other, safety always wins. Any option that compromises a procedure, conceals a defect, or rushes a check is almost certainly wrong, regardless of how reasonable the other priority sounds.
Choose options that report and clarify, not options that decide unilaterally
Train drivers operate inside a tightly coordinated system. The right answer is usually to escalate, report, or seek clarification — not to make a personal judgement call on a safety-critical issue. Acting alone is rarely the correct response.
Look for the response that protects the safety culture, not just the immediate outcome
An option that 'gets away with it' this time is still a poor answer if it conceals an error or weakens the reporting culture. Assessors are looking for candidates who would still report a near-miss even when no one would know.
Avoid the extremes
The least appropriate answer is usually obvious — ignoring a safety concern, lying, or refusing to communicate. The most appropriate answer is usually the calm, proportionate, by-the-book response. The two middle options are designed to look plausible but each compromises something important.
Work through several practice scenarios before assessment day
Pattern-recognition matters. Once you have worked through five or ten scenarios you will start to see the same competencies coming up — safety vs. pressure, reporting culture, clarification under uncertainty, customer service vs. dispatch. Recognising the underlying competency makes the right answer obvious.
FAQ
Common questions about the SJT
What is a Situational Judgement Test?
A Situational Judgement Test (SJT) is a psychometric assessment that presents you with realistic workplace scenarios and asks you to judge how appropriate different responses would be. For train driver applications, the scenarios focus on safety, rule compliance, communication under pressure, customer service, and reporting culture — the everyday judgement calls a driver makes.
Do all UK train operators use an SJT?
Most major UK train operating companies use a situational judgement assessment at the online screening stage — including operators in the Govia Thameslink Railway group, LNER, Northern, Southeastern, GWR, ScotRail, and others. The exact format varies between operators and between intake rounds, but the underlying competencies tested are consistent across the industry.
How is the SJT scored?
Most train driver SJTs ask you to pick the most appropriate and least appropriate response to each scenario from a set of options. Each scenario typically has a model answer agreed in advance by subject-matter experts, and your score reflects how closely your judgement aligns with theirs. There are no trick questions — answers that prioritise safety, clear communication, and following procedures consistently score well.
Can I prepare for an SJT?
Yes. While SJTs are designed to assess your underlying values and instincts, preparation helps in two ways. First, working through realistic scenarios calibrates your sense of what the operator considers appropriate. Second, understanding the underlying principles — safety over schedule, honest self-reporting, clarification over assumption — makes it easier to identify the right answer when you're under time pressure on the live test.
How long does the SJT take?
Most train driver SJTs run for around 25–45 minutes and contain 12–25 scenarios. Some operators include the SJT as part of a longer online assessment battery that may also include numerical, verbal, or basic cognitive reasoning. Check your invitation email for the exact format your operator uses.
Is this the same as the official SJT?
No. This is an independent practice resource. We are not affiliated with any train operating company or test publisher. Our scenarios are original content designed to model the format and competencies typically tested in UK train driver SJTs, so you can practise the reasoning before assessment day.
