Learning from Chiltern Green: Why Safe Planning Starts with Clear Communication

In April 2024, a track worker narrowly avoided a catastrophic incident at Chiltern Green, where a train travelling at over 100 miles per hour passed just moments after the individual had stepped off an underbridge. The RAIB report published this month offers not only a forensic analysis of the sequence of events that led to the near miss, but also delivers a sobering reminder of the very real risks that exist when even seemingly minor procedural oversights occur in safety-critical environments.


The individual involved (a tester undertaking telecommunications cable work) was returning from a welfare break and crossed a bridge which had restricted clearance but lacked the proper warning signage. The emergency brake application by the train driver and subsequent investigation revealed a chain of failings that extended from inadequate planning documentation and an absence of clear briefings to the inappropriate use of informal access routes not sanctioned by the project’s original safety plan.


It is easy to attribute such incidents to individual errors or unfortunate miscommunication, but that interpretation does little justice to the complexity of workforce logistics in modern infrastructure projects. What the Chiltern Green case highlights with painful clarity is that the presence of competent individuals on site does not in itself equate to a competent system of work. A person may hold the correct certification and understand the general risks associated with rail environments, but without precise, site-specific information and a structure of accountability that ensures briefings are thorough and understood, that competence can quickly be undermined by unclear expectations and systemic fragmentation.


The report draws attention to several systemic issues that many in our industry will find familiar: a disconnection between planning and delivery teams, incomplete records of signage assets, and gaps in communication that arise when multiple access points or sites of work are involved. These are not abstract problems, they are operational realities that directly impact the safety of frontline personnel. The bridge in question, though recorded internally as having restricted clearance, was not fitted with signage to reflect this. Moreover, the individual responsible for leading the team on the day had not been given clear guidance on the walking route that should have been taken, nor had they played a meaningful role in the planning process itself.


While Network Rail and its partners must now respond to the RAIB's formal recommendations, those of us working within infrastructure recruitment must also reflect. The risk does not lie solely in the actions of individuals, but in how those individuals are deployed, supported, and integrated into larger project systems. At Deploy, we understand that recruitment cannot be divorced from compliance, that safety is not simply a box-ticking exercise but a culture to be embedded, and that the quality of deployment planning directly shapes the conditions in which work is carried out.


For us, incidents like Chiltern Green underscore the importance of collaborative workforce planning, where our consultants don’t just fill vacancies but advise on workforce structure, mobilisation logistics, and role-specific risk profiles. This approach is not just strategic, it is ethical. When lives depend on precision and clarity, good enough is never good enough.


If your organisation is navigating the complexities of safe, compliant, and efficient workforce deployment across rail or infrastructure projects, we invite you to talk to us. Deploy offers more than recruitment; we provide insight, structure, and the assurance that every worker placed is part of a system designed to protect them.

After months of essential engineering work, the historic Blackheath Tunnel in southeast London has officially reopened—marking the end of a major £10 million upgrade project that promises to make journeys safer and more reliable for passengers.

UK infrastructure is facing a talent crisis. With a projected £750 billion investment over the next decade in areas such as rail, energy, roads, and flood defences, the pressure on skilled professionals from engineers to site supervisors has never been greater. Yet despite record funding, without strategic workforce planning, these bold ambitions may falter at the execution stage. Labour shortages are already causing average project delays of three to six months, with nearly 61 percent of engineering employers struggling to find candidates with the right expertise. The root cause is clear: infrastructure delivery is talent-intensive. Workforce scarcity directly translates to higher costs, fragmented schedules, and diminished quality. With nearly 40,000 vacancies in construction and engineering roles ranging from welders to high-voltage specialists and a wave of retirements ahead, the capacity to deliver complex schemes is being eroded. Even robust governance frameworks, such as those outlined in the IPA’s ‘Construction Playbook’, hinge on deeper succession and capability planning elements that cannot be ignored. Consider the A9 dualling project in Scotland or the Thames Tideway Tunnel in London, both critical infrastructure schemes that have been repeatedly delayed. The A9 upgrade was postponed from 2025 to 2035, partly due to shortages of civil engineers and project managers. And the Tideway Tunnel, a £4.2 billion sewer project, encountered setbacks when specialist technicians became unavailable. These cases illustrate the stark reality: even well-funded, high-profile projects stagnate when the right people aren't in place. That is where strategic workforce planning comes in. It’s about more than hiring; it’s proactive: predicting demand, developing talent pipelines, and deploying teams before crises emerge. Organisations must understand which skills are needed, when, and in what quantities, ensuring every phase from initial design to commissioning is staffed with fully competent professionals. At Deploy, we specialise in embedding that strategic foresight into your talent strategy. Our consultants create end-to-end workforce roadmaps aligned with project timelines and skill requirements. Through talent forecasting, succession planning, and targeted sourcing, we help clients access hard-to-find engineers, technicians, project controllers, and site leads, and keep those roles filled through to delivery. For example, we recently worked with an energy network operator facing a shortage of high-voltage engineers ahead of a major substation upgrade. By identifying the skill gap 12 months before project start, deploying bespoke training partnerships, and sourcing both experienced hires and apprentices, we secured a full complement of experts, avoiding costly delays. The future of UK infrastructure depends on two interlinked pillars: capital and capability. Funding alone will not deliver HS2 extensions, renewable energy deployments, or 1.5 million new homes. But with strategic workforce planning, supported by partners like Deploy, organisations can bridge the technical talent gap and build projects with resilience from day one. If you’re preparing for your next infrastructure milestone, talk to Deploy. We’ll help you forecast talent needs, secure specialist hires, and strengthen your delivery capability, ensuring your projects not only start but also finish successfully.
