Learn how a multi-million-pound overhaul of Darlington station is strengthening rail connectivity on the East Coast Main Line while creating a more accessible and welcoming passenger experience within a treasured Victorian landmark.
Few places are more closely tied to the origins of the modern railway in Britain than Darlington. It was here, in 1825, that the Stockton and Darlington Railway opened, carrying passengers on what is widely recognised as the world’s first public steam‑hauled railway journey.
Two centuries later, the town’s station remains a critical interchange on the East Coast Main Line, connecting local, regional and long-distance services across the North East of England and beyond.
Today, Darlington station is at the centre of a £140 million masterplan to upgrade the station and surrounding areas, strengthening connectivity across the region and creating a more accessible, welcoming and future-ready place for passengers. The wider regeneration includes new platforms, improved station access, better connections to surrounding streets and public spaces, and enhanced passenger facilities.
Led by Tees Valley Combined Authority (TVCA) and Network Rail, the station upgrade forms a cornerstone of this wider regeneration, delivering the rail capacity and access improvements needed to support the masterplan’s ambitions.
Working for BAM UK & Ireland, AECOM supported the design of the two new platforms, the footbridge linking the new station building to the existing station, the fit-out of the new building concourse area and the supporting rail infrastructure, from early concept through to delivery.
Delivered while the station remained operational, the upgrade was designed to be implemented within a Grade II* listed building, introducing modern enhancements while carefully protecting the historic character of one of Britain’s most significant railway landmarks.
The Darlington station upgrade underway
Expanding capacity and improving the passenger experience
At the centre of the scheme are two new platforms on the eastern side of the rail corridor, increasing capacity and operational flexibility on a busy section of the East Coast Main Line – and improving links between Darlington, London, Newcastle, Edinburgh and the Tees Valley.
The scheme includes a new station building and upgraded entrance hall, creating a clearer, more welcoming arrival and improving wayfinding through the space. A striking new footbridge links the new platforms with the existing station, providing step-free access and opening up previously unseen views of the historic clocktower, bringing old and new parts of the station together.
Beyond the main building, the wider project – delivered by TVCA and its partners – includes a new multi-storey car park with more than 650 spaces, a new entrance and transport interchange area linking the station with Central Park, and upgrades to the Victoria Road entrance on the western side of the site. New road layouts, wider pavements and improved walking and cycling routes also make the station easier to reach – whether on foot, by bike or by public transport.
Heritage as a design driver
Darlington station’s historic character shaped every design decision. As a Grade II* listed building, careful protection of its fabric was a key consideration from the outset.
We brought in heritage specialists as part of the design team and supported early engagement with the local planning authority and Historic England. This helped ensure new interventions complemented the station’s original architecture.
As Mark McIntosh, Regional Director at AECOM, Europe and India, and Architectural Technical Design Lead on the scheme, explains: “Protecting and preserving historic assets and the station’s heritage is an important requirement of this regeneration project. The beauty of the station’s original designs has been a constant source of inspiration for this revitalisation.”
That thinking is reflected most clearly in the new footbridge, which blends modern engineering with older feats of engineering while complementing the station’s Victorian architecture.

Integrating station architecture and trackside rail infrastructure
Alongside the station buildings and public spaces, our rail teams designed the trackside infrastructure needed to bring the new platforms into use and connect them safely into the live East Coast Main Line.
We designed the platforms and track interfaces, working closely with rail partners to coordinate track layouts, signalling and overhead line equipment. Our scope also included supporting infrastructure such as lineside cable containment, foundations for signals and equipment housings, and points heating apparatus (to prevent switches freezing in cold weather).
To enable the new layout, we also designed the widening of Smithfield Road bridge so the railway could pass safely over it. Where existing Network Rail facilities were affected, we provided replacement maintenance access routes and laydown areas so that teams would continue to have safe access to the railway once construction was complete.
This joined-up approach ensured station design, platforms and rail systems were developed together, supporting safe and efficient operation once the new infrastructure was brought into use.
Collaboration from design through to delivery
From the outset, we brought together architects, engineers and rail specialists into a single multidisciplinary team. The station, platforms and rail infrastructure were developed in parallel, allowing interfaces to be resolved early and operational requirements to shape the design.
Digital visualisations were used throughout to test ideas and communicate proposals, helping partners and stakeholders understand how the station would look and function as it evolved.
Working closely with BAM UK & Ireland and Network Rail, we maintained a regular site presence from early design through to construction. This helped resolve issues quickly, manage interfaces with third-party rail systems and align design decisions with construction sequencing.
We also worked with local authorities and delivery partners to ensure the station upgrade aligned with surrounding improvements, including the Victoria Road entrance, car park, pick-up and drop-off facilities, and wider public realm changes, improving access and connectivity across the area.
“The beauty of the station’s original designs has been a constant source of inspiration for this revitalisation.”
Keeping the railway moving during construction
Keeping the station operational throughout construction was essential. Trains continued to run and passengers continued to use the station while major new infrastructure was delivered around them.
We designed the works to be delivered in carefully planned phases, with only brief periods of track closure used where necessary. Temporary routes and safety measures were put in place to minimise disruption, while close coordination with operational teams helped maintain reliability throughout delivery.
A more accessible and connected station for the future
Alongside protecting its historic character, the upgrade significantly enhances accessibility. New lifts and escalators provide step-free access across the station, making it easier for passengers with reduced mobility, luggage or pushchairs to move between platforms and entrances.
Two hundred years after Darlington helped launch the modern railway, the station continues to evolve as a key gateway for the North East, strengthening connections across the region.
By combining integrated design, close collaboration and sensitive intervention within a historic setting, the project ensures Darlington station continues to serve as a modern, accessible and future-ready transport hub for generations to come.
