I used to take Metro-North from New Rochelle down to Grand Central, and I miss it so much. Four trains an hour during the rush, always arriving within a minute or two of schedule. The 8:03 Amtrak between Baltimore and DC hasn't been on time in two weeks. As for the wide socieconomic spectrum--the only thing that ever bothered me about the crowd on MNR was the drunk suburban kids that'd take the 1am with me Saturday morning. Nothing like coming home from a long day at work and having some 19 year old Westchester brat puke all over the floor.
