Colas Rail resulted from the merger of two companies acquired by Colas Group. The merger brought together two of Europe’s major players in the railway sector and pooled their skills within one entity. Colas Rail UK was formed in 2007, firstly renovating tracks in the Western region in 2008, before entering the rolling stock market in 2009 and purchasing new tamping machines in 2010. After being awarded our first Network Rail Haulage contract in 2013, we have gone from strength to strength delivering major track infrastructure projects for Network Rail and the Midland Metro Alliance contract in Birmingham.

We are among the UK’s leading rail infrastructure service providers and are recognised as one of Network Rail’s five largest contractors. Operating the UK’s largest fleet of rolling stock and freight, we have secured a series of major long-term contracts and are looking to continually build long-term collaborative relationships with clients and partners in the future.

We specialise in:

• Track laying, renovation and maintenance
• Freight
• Lighting / underground railway lines / tramlines.
• High voltage lines and electric traction power
