Transforming UK Rail
WJ’s Role in a Landmark Project 

High Speed 2 (HS2) is the UK’s most ambitious rail infrastructure project, set to revolutionize connectivity between London, the West Midlands, and eventually Northern England and Scotland. As the largest rail investment in UK history, HS2 is designed to cut journey times, boost capacity, and support sustainable transport across the country.

Nearly half of the 140-mile stretch between London Euston and Birmingham city centre will run through tunnels—highlighting the scale and complexity of the engineering involved.
