But... think how the Cotswold Line redoubling would help FGW▸ . Less delays through Reading caused by single track, less delays throughout the region.
Excuse me for acting thick
but please explain how a train running late off the single line at Swindon causes noticable delays at Reading. I haven't had many considerable delays over the Kemble branch for ages and there is enough slack in the timetable between Swindon and Reading for even the windyest of drivers to make up the small amount of time lost recently
. However that said there is a case for the upgrade to double track required along with more signals to enable more trains both freight and passenger to run!
