The 2 years of Engineering Access Statement (
EAS» ) - formerly the rules of the route - is publicly available online, currently up to December 2014, within a few weeks they'll put up 2015's info:
http://www.networkrail.co.uk/aspx/3741.aspxAlthough it takes some wading through to find the actual engineering works calendar which are in section 7, with separate sections for each
NR» route, and then it gets superseded by other documents as the planning becomes more refined, for someone wanting to know broadly what's being done month by month it's a reasonable start.
With the benefit of hindsight it's been reasonably accurate for Reading re-development...
