A construction apprentice from Walthamstow had a brush with royalty when he helped show Prince Charles around a building site for the new Crossrail railway.

Bob Gridley, 34, is one of 130 apprentices working across the 40 construction sites that are building the 118 kilometre route through London.

Mr Gridley, of Higham Hill Road, was among a select group of workers who gave a tour of the works in Farringdon to the Prince of Wales and his wife the Duchess of Cornwall last week.

Mr Gridley is undertaking an 18 month Spray Concrete Lining apprenticeship with Crossrail contractor BAM Nuttall, and has been working 25 metres underground on new platforms and tunnels.

He said: “To find out about the apprenticeship training on Crossrail and then apply and get the job was really pleasing.

"It’s great to be working on something I can feel passionate about and that actually means something.

"The Tube is 150 years old so the idea that I’m now building something like Crossrail that’s still going to be around and in use in another 150 years is quite incredible.”

Crossrail, which will cost an estimated £14.8billion to build, is due to open in 2018.
