The college is part of government plans to train prospective engineers and construction workers to develop HS2 and other rail projects, as it looks to plug a potential post-Brexit skills gap.
The steel-framed Doncaster facilities are joined by a second campus in Birmingham, both of which were built by Willmott Dixon as part of a £52M contract.
Secretary of State for Education Justine Greening (pictured) said: “It has been great to attend the official launch of the NCHSR. It’s part of how we are steadily transforming technical education in this country, training up a new generation of skilled young people and the existing workforce so that British business has the skills it needs and people have the opportunities they want – a win-win for everyone.
“We can only do this in partnership with employers – the NCHSR is just one great example of this. The impressive new building and training facilities are at the forefront of our ambitions to create a world class system of technical education.”
