There's plenty of infrastructure clearance work going on now, mainly track
lowering and bridge rebuilding. A significant number of overbridge sites
on the stretch between Reading and Didcot looked like a disaster zone just
after the Christmas and New Year break. Civils work of similar nature has
just started between Reading and Newbury as well.

The bridge rebuilding was done as part of Southampton to Midlands freight
gauge enhancement (though was done to giver clearance for OHLE as well).
