Rail's skills gap: How employers can prepare for an ageing workforce

The rail industry has always relied on highly skilled professionals to keep Britain's infrastructure moving safely and efficiently. From signalling specialists and engineering supervisors to possession planners and safety-critical operatives, many of the sector's most experienced workers have spent decades developing expertise that cannot be replaced overnight.

However, a significant skills challenge has been emerging across the industry for some time, with no clear solution in sight. A significant proportion of the rail workforce is approaching retirement, while employers continue to struggle to attract sufficient new talent for key technical and operational roles. A recent parliamentary report has warned that UK rail is facing a critical skills crossroads, with an ageing workforce and widening capability gaps threatening the sector’s ability to deliver a once-in-a-generation programme of investment.

The result is what many describe as a rail skills cliff edge: a point at which years of knowledge, experience and capability risk leaving the industry faster than they can be replaced. The good news is that employers can act now to protect their future workforce by recognising that the challenge is not simply recruiting more people. It is ensuring that the next generation is ready to carry the industry forward.

The challenge facing the rail workforce

Skills shortages are nothing new in rail, with the National Skills Academy for Rail’s (NSAR) workforce research highlighting this ongoing challenge. Employers have long competed for experienced professionals across engineering, signalling, maintenance and safety-critical disciplines. However, when employers identify potential skills gaps, the instinct is often to focus on hiring. But while recruitment plays an important role, it is only part of the solution.

Many of the roles experiencing shortages require years of training and industry exposure before individuals reach their full capability. Finding experienced candidates in an already competitive market can be difficult and costly.

This means employers need to think beyond immediate vacancies and focus on long-term workforce sustainability. Building future-ready teams requires a combination of recruitment, development, mentoring and succession planning.

In other words, businesses need to grow talent as well as attract it.

Preserving knowledge before it walks out the door

One of the biggest risks associated with an ageing workforce is the loss of knowledge. Experienced rail professionals often hold information that extends beyond technical qualifications. They understand local networks, operational practices, stakeholder relationships and lessons learned from previous projects.

Capturing this expertise should become a strategic priority. Forward-thinking employers are increasingly introducing structured knowledge-transfer programmes that encourage experienced employees to share their insight with younger colleagues before retirement.

This can include:

• Mentoring programmes
• Job shadowing initiatives
• Skills-sharing workshops
• Documenting best practices and lessons learned
• Cross-generational project teams

By creating opportunities for knowledge exchange, businesses can preserve valuable expertise while helping newer employees develop more quickly.

Succession planning shouldn't start when someone resigns

One of the most common workforce planning mistakes when dealing with an ageing workforce is treating succession planning as a reactive exercise. Succession planning should begin years before critical roles become vacant and well before retirement begins.

Employers need visibility of their workforce demographics, anticipated retirement timelines and future skills requirements. Understanding where capability gaps may emerge allows employers to make informed decisions about recruitment, training and development.

Why apprenticeships and early careers matter

If the rail industry is to address long-term skills shortages, it must continue to attract new entrants to the sector. Apprenticeships, graduate programmes and early-career opportunities all play an important role in building sustainable talent pipelines. NSAR’s 2025 Rail Workforce Survey shows why this pipeline matters: workers aged 25 and under account for just 6.8% of the rail workforce, while more than 30% are aged 50 or over. Without stronger early-career routes, the sector risks losing experienced capability faster than it can bring new talent through.

These pathways provide opportunities for individuals to develop technical skills while gaining practical experience within real-world environments. They also help businesses shape future capabilities to meet the evolving needs of the industry.

However, employers should view apprenticeships as part of a broader workforce strategy rather than a standalone solution. Future workforce planning requires a balanced approach that combines experienced professionals, emerging talent and continuous skills development across all career stages.

The skills needed in the future may be different

The succession challenge in rail is not simply about replacing retiring workers on a one-for-one basis. The rail workforce is evolving alongside advances in digital technology, automation, remote monitoring and data-driven decision-making.

The professionals entering the industry over the next decade are likely to require a blend of traditional rail expertise and emerging digital skills. This creates an opportunity for employers to think strategically about the future capabilities they need, rather than focusing solely on historical job requirements. Building future-ready teams means preparing for the railway of tomorrow, not just replacing the workforce of yesterday.

Building the next generation of rail expertise

The rail industry's skills gap retirement cliff is not inevitable. While an ageing workforce presents real challenges, it is also an opportunity to strengthen talent pipelines, modernise workforce strategies and create more sustainable approaches to skills development. Employers that act now can protect valuable knowledge, develop future leaders, and build the capabilities needed to support the next generation of rail infrastructure projects.

The question is not whether the industry will experience workforce change. That change is already happening. The real question is whether employers are preparing today for the skills they will need tomorrow. For rail businesses looking to strengthen workforce resilience, succession planning is no longer a future challenge. It is a priority that starts now.
