Future of London transport revealed at secret site
A vision of the future of transport has been built at a secret location in Bedfordshire - a life-size model of a Crossrail station platform.
Crossrail is the massive project to link east and west London and is due for completion in 2018. The model will help designers and engineers make the right decisions about how the stations will look and feel.
Mike Ramsden takes a look at what some of London's new station platforms will look like in seven years.
