Every train journey, whether a cross-country adventure on Amtrak or a mundane daily commute on Metro-North, starts with the same thing: a train station. Consider Grand Central (Terminal, not Station). The architecture is so rich, the spaces so varied, that any time spent in this cathedral to transportation is time well spent. You can have a sit-down meal or grab a beer and a sandwich, pick up a newspaper, or a new iPhone — it’s all there. GCT is clean (mostly), well patrolled and filled with people, each giving the others a shared sense of safety and community.
