Working on the London Underground isn't something you can simply turn up and do. Before anyone sets foot on the network's infrastructure, they'll need to hold specific qualifications that prove they can work safely in one of the UK's most complex, high-risk environments. The Underground runs around the clock, carries millions of passengers, and operates with live traction current, active train movements, and confined spaces that demand careful management.
Whether you're a contractor, operative, or supervisor, getting the right training is a legal and operational requirement. Here's a closer look at six key courses that workers will need to consider, and what each one will prepare them for.
1. Worksite Safety Induction (LU-WSI)
Before any other London Underground qualification can be pursued, workers must complete the London Underground training courses starting point: the Worksite Safety Induction (LU-WSI). This is the mandatory entry-level course that grants access to LU worksites, and it's a prerequisite for every other qualification on this list.
The LU-WSI covers everything from health and safety procedures and site access controls, through to fire prevention, asbestos awareness, and working at height. Workers will also be expected to understand fatigue management and how to safely operate around escalators and moving walkways.
2. Basic Track Awareness (BTA)
Once the LU-WSI is completed, the Basic Track Awareness (BTA) course is the natural next step. It's mandatory for anyone who'll need to access the track in an operational setting, whether that's during engineering hours, traffic hours, or within depots and possessions.
The BTA qualification teaches workers how to recognise and manage hazards in the track environment, including the risks associated with live traction current. They'll also learn communication procedures, how to work under protection, and how to identify and report incidents. Both an initial and a refresher course are available, making it straightforward for experienced workers to maintain their compliance.
3. Protecting Workers on Track (PWT)
The Protecting Workers on Track (PWT) suite is designed for those with responsibility for keeping colleagues safe while working on or near live LU infrastructure. It isn't a single course but a collection of four specialist pathways, each addressing a different working context:
Engineering Hours (PWT-EH)
Traffic Hours (PWT-TH)
Depots (PWT-D)
Train Movements (PWT-TM)
Each pathway is aligned to current LU rules and legislation, preparing delegates to manage worksites confidently in their specific environment. A valid LU-WSI and BTA are required before attending any PWT course.
4. Site Person in Charge (SPC)
Those taking on a supervisory or leadership role at an LU worksite will need the Site Person in Charge (SPC) qualification. This course gives delegates the authority and knowledge to plan, oversee, and control safe work activities across the Underground network, protecting both personnel and assets.
Delegates will come away knowing how to apply LU operational rules, communicate effectively with Protection Masters and Controllers, and identify and mitigate hazards in a live rail environment. The course draws on scenario-based discussions alongside classroom learning to give delegates practical confidence. Like other courses in the LU pathway, the SPC is available as both an initial and refresher qualification.
5. Track Trolley Controller (TTC)
Workers responsible for the safe movement of materials and equipment using track trolleys will need the Track Trolley Controller (TTC) course. It covers the full lifecycle of track trolley operation, from assembly and pre-use safety checks right through to disassembly and storage.
Learners will also cover how to supervise the loading and unloading of materials, how to operate safely under protection and within defined track zones, and the communication procedures needed to coordinate with track teams. The course combines classroom instruction with hands-on practical training, giving delegates real confidence in controlled and live LU environments.
6. Fire Watchperson (FWP)
Anyone involved in or overseeing hot work activities on London Underground premises such as welding, grinding, or cutting, will need to complete the Fire Watchperson (FWP) course. Fire risk in confined underground environments is a serious concern, and this qualification equips workers to manage it effectively.
The course teaches delegates to recognise and assess fire risks, monitor work areas for signs of combustion, and react quickly and correctly in the event of an incident. It also covers LU safety procedures and emergency response protocols, along with effective communication with on-site teams and safety controllers. A valid LU-WSI is required before attending.
Closing Up
Each of these six courses forms part of a structured competency pathway on the London Underground. They're designed to build on one another, starting with the LU-WSI and progressing through to specialist roles. Whether you're just starting out on the network or you're an experienced operative looking to renew existing qualifications, having the right certification in place is what keeps you, your colleagues, and the wider network safe.
Always make sure that training is delivered by experienced practitioners with real-world rail backgrounds, combining classroom theory with practical environments that replicate genuine LU working conditions.
