Across the middle of North Bucks, the rebuilding of the 1850 railway is steaming ahead. Many local roads have been closed while works are carried out for the East West Rail project.
The project will create a rail link between Oxford and Cambridge, much of it on the routes of long closed lines, though there will be a brand new stretch of line on the far side of Bedford.
Often, it seems, the road are closed simply to keep a safe distance between workmen and the general public, but at Bletchley the road is closed while the 2,000 feet long railway flyover is being extensively rebuilt. The flyover was first in use in 1959.
The great piers are remaining, but a huge crane has been lifting the heavy concrete spans away one at a time. The first span was lifted in two parts, as it weighed 295 tonnes.
