Because the IE website upgrade broke a lot of existing links including the Network Statement
I have uploaded it to Scribd. Obviously some of the info in it is going to be stale because of upgrade work done in 2011 but some may find it helpful when trying to understand stuff like why Rosslare 22K trains can't be 6 car length etc.
Interestingly it lists the Roscrea 2nd platform as active which is presumably an oversight on whoever compiled the data's part since we know from the issues around the new evening services that that platform is not in use. It was a draft admittedly but they never did upload the final version. Hopefully IE will get around to publishing another some time in the next decade.
