Centenary News

Going underground to keep London connect-ed

​It’s #throwbackthursday and we’re looking back to 2004 when our London rail team was going underground to help upgrade communications systems for the London Underground.

Blooming Marvellous

​Nothing says Spring – or ‘Happy Centenary’ - like a host of golden daffodils.

Inspiring the Engineers of Tomorrow

We have a proud history of training apprentices and developing the next generation of engineers – and that means we also work hard to promote careers in engineering and inspire the engineers of tomorrow. Our industry is facing a skills shortage and research shows that many young people aged 11 to 19 don’t know much about what engineers do or the many career opportunities it provides - and we want to change that.

A track record delivering rail projects

​Bringing buildings and infrastructure to life is central to the NG Bailey vision and our long history in the rail sector has seen us improving the travelling experience for rail users at some of the busiest stations in the UK.
