Google Maps has announced a new update to the Transit site. When you visit, now you'll find a map with markers showing every city where full schedule routing is available.
It's been quite a couple of weeks for Google Maps and their transit features. Earlier this week, Google and New York City launched nycgo.com and opened a public Information Center in Manhattan. A week ago, Google launched a new Transit layer in their Maps feature.
