What We Do

Rail Infrastructure

We specialise in delivering complex rail infrastructure projects in collaboration with our customers, stakeholders and our supply chain partners. Our dedicated teams possess a deep understanding of the railway, helping us to develop safe and efficient solutions that consider the needs of the passenger during design, construction and throughout the life of the new infrastructure.

Our experience affords us the ability to advise and support our customers in developing cost-effective practical solutions to keep the railway moving.

Rail Services

We are committed to keeping our fleet on track and fully operational at all times. With dedicated facilities and fully trained maintenance staff, we operate a 24/7 service all year round and provide a high level of expertise in rail operations and logistics across the UK.

Our services include the operation and maintenance of On Track Plant and Rail Freight, Rolling Stock Refurbishment and Maintenance, as well as Rail Grinding and Milling services.

Our maintenance depot accommodates On Track Plant and Locomotives up to 148m long and undertakes the servicing and repair of our On Track Machines, Plant and Locomotives by our fully trained staff. We also have operational depots across the breadth of the country, enabling us to offer nationwide coverage.


Urban Rail

We have over 25 years experience’ in designing and delivering Light Rail systems in more than 50 cities around the world.

In the UK, we deliver design, construction and maintenance for light/metro rail projects. Our range of skills and experience affords us the capability to offer our customers a flexible service, focused to meet their specific needs. We seek to work in partnership with our customers to identify optimal engineering and value-based solutions through Early Contractor Involvement, considering the impact of design decisions on a whole life cost basis.

Urban Rail transit offers low energy consumption and high efficiency travel, opening up under-populated areas and aiding regeneration. Increasingly becoming an integral part of urban planning, it provides one of the most convenient and safest modes of transportation within inner city areas – enhancing regional quality of life and having a positive impact on the local community, the environment and the economy.


High Speed Rail

We have been involved in key strategic projects in France, Germany, Italy, Belgium, Morocco, South Korea and the UK.  
We have delivered the track on 14 high speed lines in both ballastless and ballasted track systems in open route and tunnels extending to over 6602 Single Track Kilometres (STK).  

Colas Rail’s high-speed Overhead Catenary Systems (OCS) experience is significant having delivered 4151STK many of which currently operate at 320km/h.

Our services include project management, coordination, installation, testing and commissioning and maintenance as well as the integration of our supply chain for the benefit of our clients, stakeholders and rail network users.
