Rail infrastructure such as this will the life blood of the economy going forward. You can see that in any city abroad that you visit.
The gas thing is that most motorists going to Dublin from Navan every day use the old untolled N3 to avoid the tolls and the government is using the mobile speed detecting van to try and nab them every 2nd week on the stretch into Dunshaughlin and frighten them onto the M3. That infrastructure is a pure white elephant. The rail link won't be, not the way fuel costs and congestion are going.
It might be there for my retirement in 20 years!
