Transit

Transit networks for thriving cities.

Modernization of our urban transportation systems comes with many challenges.

Planning and regulatory approval. Existing underground infrastructure. Carbon reduction goals. Safety. Cost and schedule control. 

Whether starting the first line of a new system or expanding and improving existing networks, these are familiar issues for owners, operators, and constructors.

What can we do for you?

Successful  transit projects benefit from deep technical knowledge, experience, and a broad range of skills. That’s what you will get from us. We’ll work with you to develop the right solution for you, your customers, and communities. 

Find better solutions faster. Our use of digital solutions enables rapid optioneering, stakeholder engagement and feedback, and design optimization. Our digital tools, systems, and ways of working enable collaboration, creating integrated project teams.  

Manage complexity. Transit networks combine large-scale physical structures, such as stations and tunnels, with a wide array of complex supporting systems. This is where our multisector, multidisciplinary capability is at its best. We understand the requirements and how they interface.  

Maximize socioeconomic benefit. We work with you to achieve the greatest positive impact for your customers and communities. We can help you to create solutions that navigate the interface between trains, platforms, station concourses, and public realm which are intuitive and safe to use — and that maximize wider social, health, and environmental outcomes. 

Cut carbon and build resilience. Transit infrastructure owners and operators face a dual challenge: how to reduce and eliminate carbon emissions, and how to make their operations more resilient. Carbon management is integral to all our projects, frequently delivering cost savings as well as reducing emissions. We will also work with you to manage physical climate change risks and build long-term operational resilience.

Engineering modern transit for urban connectivity

Our experience

Our founders worked on the world’s first deep-level underground “tube” railway in London at the end of the 19th century, and we continue to support transit agencies and contractors around the world to create, maintain, modernize, and expand their networks.

  • Elizabeth line, London, England
    Our 30-year journey to bring London’s newest rail line into operation included route alignment, planning and approvals, excavation of26 miles (42 km) of tunnels under the city’s streets and buildings, station design, the integration of more than 50 systems, and the interface with existing services.
  • Northern line extension, London, England
    This 1.8-mile (3 km) extension to the Charing Cross branch of London Underground’s Northern line connects an area previously poorly served by public transportation. We combined digital tools and alternative construction solutions to deliver the line and design two new stations that provide the foundations for multistory buildings above.
  • Ontario Line, Toronto, Canada
    At 9.7 miles (15.6 km) long and with 15 stations, the line is the biggest of four current subway expansion projects in Toronto. We have helped prepare the way for its construction by defining and de-risking the works, as well as setting out stretching requirements for sustainability, quality, and value for money.
  • Regional Connector, Los Angeles, USA
    As detailed designer, we successfully navigated the challenges of earthquake risk and tangles of existing utilities to transform journeys for LA Metro passengers.
  • Sound Transit, Seattle, USA
    Working with the regional transit agency to radically expand its transportation infrastructure for a more sustainable future of community connectivity across Seattle. Our partnership with the agency has been forged over two decades and we are now providing multiple services, including rail systems engineering, construction oversight and inspection, systems integration, and interface management project controls.
  • Sydney Metro, Australia
    Over the next decade, the metro system will grow to encompass 46 stations and 70 miles (113 km) of track, helping the city’s residents go about their daily lives quickly and conveniently and enabling further growth of the extended urban area. Our role has evolved from designer and technical advisor to a trusted delivery partner.
  • Uithoflijn tram extension, Utrecht, Netherlands
    Uithoflijn is a 5.6-mile (9-km) light rail line in the Netherlands that replaced a bus route that was increasingly struggling to cope with high passenger demand. Our role over more than eight years included supporting both preliminary and detailed design, and providing procurement, supervision, testing, commissioning, engineering consultancy, and rolling stock services.

Carbon Portal

Identify, calculate, and reduce embodied and operational carbon emissions. This infrastructure carbon calculator is aligned to PAS 2080, the international specification for managing carbon across the built environment (coauthored by Mott MacDonald). It allows anyone across your business and supply chain to identify and calculate carbon emissions, not just carbon experts.

STEPS

STEPS was the first solution to map people in motion, from transportation interfaces to stadium evacuation. STEPS realistically simulates pedestrian movements to test design layouts and operational plans. It enables users to understand how people will act in daily situations and in emergencies.

TRAIN

TRAIN is world-leading software producing advanced simulations of rail systems under all conditions. The programme has been developed by us over decades and has been used on a broad range of high-profile projects around the globe. TRAIN complies with BS EN 50641 standard.
