The top rail roles keeping the UK network moving

The UK rail network is the backbone of our national infrastructure, supporting millions of journeys and critical trade movements every day. Behind the scenes, this rail network is run by a highly skilled workforce, that operates in challenging environments.

From trackside teams to supervisory roles, there’s a wealth of qualified professionals who keep Britain moving, but the sector is facing a shortage of these skilled individuals at a time when investment and demand is accelerating. Indeed, industry data has recently revealed the extent of this dearth of talent, with a significant proportion of the workforce approaching retirement and tens of thousands of roles needing to be filled in the coming years to maintain and modernise the network.

For those looking to accelerate their career in or from adjacent sectors such as engineering, there are currently many benefits to a career in rail. From competitive pay, clear progression and job security, to being part of a strong team culture and broader purpose. The opportunities are endless.

If you are considering working in the rail sector, here are some of the most in demand roles to be aware of.

Track Operative

Rail infrastructure is constantly exposed to wear, weather and increasing usage, and as the network expands and ages, the need for reliable, trained operatives remains strong. Often seen as the backbone of rail maintenance, Track Operatives ensure the safety and functionality of the railways. Track roles also act as a gateway into more specialised rail careers, making them a vital foundation across the workforce.

Key responsibilities include:

• Inspecting and repairing track, sleepers and ballast
• Maintaining bridges, tunnels and drainage systems
• Clearing debris and responding to weather-related damage
• Supporting planned maintenance and renewals works

Skills required are:

• Practical, hands-on experience (often from construction or engineering)
• The ability to work safely in high-risk environments
• Physical fitness and resilience
• Basic technical knowledge of tools and machinery

COSS (Controller of Site Safety)

Safety is non-negotiable in rail. Every project, regardless of size, requires competent safety leadership. As more projects are delivered simultaneously across the UK, experienced COSS professionals are essential to ensure worksites remain compliant and teams are protected. A Controller of Site Safety (COSS) is responsible for protecting teams working on or near the line. They ensure that all activity takes place under a safe system of work.

Key responsibilities include:

• Setting up safe systems of work before work begins
• Interpreting rule books and safety procedures
• Managing communication with teams and signallers
• Ensuring no work starts until risks are controlled

Skills required are:

• Excellent communication and leadership
• A strong understanding of safety regulations
• The ability to make quick, confident decisions
• Attention to detail and risk awareness

Engineering Supervisor

With increasing investment in rail upgrades, electrification and renewals, demand for Engineering Supervisors (ES) is rising. These professionals are critical to delivering projects safely and efficiently, making them one of the most sought-after roles in the industry. This is a highly regulated job that is critical to maintaining safety-standards in rail. Every day can bring new challenges and opportunities, but broadly speaking, an ES handles worksites, protects the line and workers on site, controls train movements and manages the activity that goes on behind the scenes across the UK’s rail network.

Engineering Supervisors also take overall responsibility for worksites during possessions (when the railway is closed for engineering work). They coordinate activities and ensure everything runs safely and efficiently.

Key responsibilities include:

• Setting up and managing work sites
• Agreeing safe systems of work with COSS teams
• Authorising movement of plant, trains and workforce within the site
• Managing site boundaries and operational control

Skills required are:

• Advanced rail experience and technical knowledge
• Leadership and coordination skills
• Strong understanding of rule book requirements
• Ability to manage multiple workgroups simultaneously

Machine Controller

Modern rail projects rely heavily on specialised machinery. As technology advances and project complexity increases, skilled professionals who can safely manage these assets are in short supply.

Machine Controllers oversee the safe operation of on-track plant (OTP), such as rail-mounted machinery used for maintenance and construction.

Key responsibilities include:

• Planning and controlling machine movements
• Briefing operators before work begins
• Managing safe operation during on- and off-tracking
• Ensuring machines operate within safety and compliance standards

Skills required are:

• Strong situational awareness and safety knowledge
• Technical operational skills linked to rail management, such as On Track Plant (OTP) operations
• Communication and team management abilities
• Risk assessment and management

Crane Controller

Heavy lifting is a core part of rail construction and maintenance. With large-scale infrastructure projects ramping up across the UK, Crane Controllers play a vital role in ensuring these operations are carried out safely and efficiently. These professionals are responsible for supervising lifting operations on rail sites, often involving heavy materials and complex logistics.

Key responsibilities include:

• Planning and coordinating lifting activities
• Managing exclusion zones and site safety
• Communicating with operators and slingers
• Ensuring compliance with lifting plans and safety standards

Skills required are:

• Strong communication and coordination
• Understanding of lifting operations and risk management
• Ability to manage high-pressure situations
• Attention to detail and safety-first mindset
