Has anyone costed an express route from Donabate to Drogheda for Enterprise/express suburban/Tara to avoid 4-tracking Donabate-Balbriggan? The right time for this was during M1 land take but we couldn't have road and rail sharing infrastructure...
I'm a bit concerned about the Clontarf GC-M50 route - property values are depressed enough so I imagine the locals won't be thrilled at the possibility of a TBM putting cracks in their foundations, given the lack of a nearby arterial to run under.
@comcor - if BXD happens Interconnector is dead, and the article above makes no reference to Heuston.
