At the start of the 21st century a new housing estate was built called Calvert Green,[3] greatly enlarging the original village.

The East West Rail project, announced in 2011, is expected to see the line reopen in 2025, with the closest station at Winslow.

The currently under construction High Speed 2 (HS2) will run along the Great Central Railway north–south corridor in this area, to the east of Calvert.

It has been noted that the convergence of HS2, East-West Rail, and the Oxford-Cambridge Expressway at this location would offer opportunities for future provision of a key regional facility, such as an airport, or a New Town
