i believe Network Rail are in the design phase for Great Western
electrification so work is happening even if nothing obvious has
turned up "on site".

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 actual wires will only appear much later, but the civils part of the
project is definitely underway...
