If you’re sitting on a Metro-North car tomorrow afternoon, and it doesn’t seem to be going anywhere, and it’s a really nice car with headrests and electrical outlets and bathrooms that, if you close your eyes, you don’t even realize they’re there, you probably got on the new demo model of the M-8 that’s on display at 2 p.m. Thurs.

MTA Chairman Dale Hemmerdinger (that name’s a real humdinger!) and Metro-North president Peter Cannitto will be there to say a few words at track 25.

The M-8s will be pressed into service on the New Haven line at some point next year.
