Should you find yourself exiting Penn station – the Amrak train station and needing a cab, anytime of day, or weather, there is another solution to standing in the long taxi line. The line seems like a logical solution if you are new to the City. And the taxis are obligated to join the line and not pick up customers around it. But they can pick up customers less than a block away, at the closest intersection. So if you arrive by train or bus, and need a cab, do the following homework: figure out if your address is north or south, and when you exit the station, head to the nearest intersection with traffic in the direction you need to go, and hail a cab there. Works like a charm
