More details about a rail line linking Cambridge and Oxford have been unveiled.
The East West rail project aims to connect the university cities, and the first section between Oxford and Bletchley is set to open in 2025.
In Cambridgeshire, two new tunnels are being proposed, as well as new stations for Cambridge South, Cambourne and Tempsford.
The scheme has been heavily criticised by some locals, but was given its backing by the new Labour government in the autumn Budget.
A public consultation on the proposals has been launched here.
