Metro North long ago removed "Commuter Rail " from their official title. Part of the the aim was draw more a of weekend and off hours crowd to come to the city. Shed itself of the 9-5 only stigma. As previously stated it will be interesting to see the commuting habits let's just say in the next 1-3 years alone.
I totally agree those mainline infrastructure improvements should of occurred years ago. I wonder how much money would've been saved with 2003(?) proposal for the third track.
