Crossrail’s final public exhibition before it transforms into a public railway has opened at the Transport Museum, showing off some of the engineering behind the tunnelling project.

At the same time, a new tunnelling gallery has opened in the main museum as part of the national programme to celebrate Year of Engineering 2018.

The Secret Life of a Megaproject explores the lesser-known stories about the Crossrail project with prototypes, construction footage in a 270 degree cinema, interactive maps and stories from the new generation of engineers who are building the Elizabeth line.

Look out for the new Elizabeth line moquette cubes — which you can buy from the museum shop, although they do cost £175 each.

The new exhibition runs until December 2018, which is also when the railway opens as the Elizabeth line for the public.

Entry to the museum is £17.50, but if you are (or want to be) a regular visitor, the membership of the Friends is just £26 and gets you unlimited entry for a year.
