Guest Writer article from Damien Lambert, Rail Director Ireland at AECOM.

Ireland’s rail network is at a crucial turning point. Ambitious plans for expansion, decarbonisation and improved passenger services are under way, and how we approach delivery today will shape the railway for decades to come. For organisations across our industry, the question is how to deliver a modern, resilient network while maintaining today’s services and preparing for tomorrow’s operations. The answer lies in adopting a programmatic, operationally grounded and people-centred approach.

First and foremost, as Ireland’s rail investment accelerates, organisations must be structured not only to deliver infrastructure but to run it effectively. Readiness was a central theme of AECOM’s Ireland Annual Review 2026 report, as we called for organisations to implement a process of strategic preparation that begins early and continues through commissioning. Workforce planning, systems integration, safety validation and trial operations all contribute to a smooth handover. Organisations that embed operational expertise throughout programme delivery are better placed to make the most of the new infrastructure and provide consistent service from day one.

In Ireland, the readiness challenge is particularly relevant due to the rapid scaling up required for the country to meet its infrastructure goals. The rail sector is now tasked with delivering an ambitious pipeline of major projects, programmes and portfolios at pace, within a system that faces numerous limiting factors while also grappling with the expectations that come with unprecedented scale. Improving readiness internally and across the delivery ecosystem will help organisations manage constraints, accelerate timelines and deliver consistently and confidently.

Achieving our rail infrastructure goals will require taking a programmatic, system-wide approach rather than approaching projects in isolation.

Fleet upgrades, electrification programmes, signalling improvements and station modernisations deliver the greatest benefit when they are coordinated as part of an integrated programme – the total benefits from the network of projects being greater than the sum of those same projects when measured individually. Treating them as a series of disconnected schemes is a recipe for inefficiency, missed opportunities and frustrated passengers.Considering how individual projects interact allows us to optimise investment, minimise disruption and deliver value for passengers more quickly.

At the same time, operations must be central to design. Railways must continue to operate while construction is underway, as decisions made during planning have long-term implications for how efficiently services can be operated. From track layouts and depot design to signalling philosophy and construction staging, integrating operational considerations into delivery helps ensure the network is maintainable, reliable, and flexible for future needs.

Key to this operations-focused approach, however, is that future planning moves beyond technical optimisation to genuine user-centred design. Service design should reflect the public’s needs – reliability, accessibility and frequency – while also considering the impact on local communities. Engaging passengers and residents early and throughout the development process builds trust, ensures better outcomes, and helps infrastructure investment deliver the benefits it promises.

Ireland also benefits from a strong history of project delivery across other sectors, including water, energy and housing, all of which will be delivering major programmes in parallel with the rail sector. This environment, alongside the significant overlap in the resource and skills pool, will provide opportunities for sharing lessons learned and best practice across sectors, helping to guide decision-making and reduce risk.

At the same time, we have an opportunity to adopt new approaches to the development of electrification, digital signalling, and data-driven asset management – where they bring measurable improvements. Combining proven practices with appropriate innovation allows us to accelerate delivery while maintaining reliability.

Finally, the success of the network depends on the people working on it – no transformation is possible without having the right skills to hand. Ireland’s rail sector faces growing competition over skills from other sectors and the rapidly changing technical demands of modern rail systems. Developing skills across electrification, digital signalling and data-driven asset management is essential, alongside maintaining traditional operational expertise.

Apprenticeships, graduate programmes, upskilling, and closer collaboration between industry, academia and government will help ensure that the workforce is prepared to effectively operate and maintain Ireland’s railways. Given the scale of ambition mapped out in the All-Island Strategic Rail Review, there is an opportunity here for Ireland’s rail sector to become a shining light for railway technology and infrastructure investment, which can attract expertise in turn. However, while international partnerships may help bridge short-term gaps, long-term resilience depends on building domestic capability. The organisations that invest in people today will be the ones securing Ireland’s railway future in the years to come.

Ireland’s rail network is entering a defining decade. The choices made now – how projects are structured, how operations are integrated, how people are engaged, and how skills are developed – will shape the system for generations.

Success will not be measured solely by kilometres of track electrified or stations upgraded, but by the creation of a railway that is reliable, resilient, and centred on the needs of passengers and communities. By embracing a programmatic approach, grounding delivery in operational reality, and investing in people and knowledge, Ireland can build a rail network worthy of its future.
