Google, Meet the MTA. MTA, Meet Google.

Read/Write Web is reporting this morning, via Bloomberg, that Google may be working with the Metropolitan Transit Authority and New Jersey Transit on incorporating New York City's subway and train system into Google Transit.

Google Transit currently covers 15 transit systems worldwide, which includes all of Japan and several major US cities. Google won't confirm that it's talking to the MTA and NJT, but both the MTA and NJT confirmed that they were speaking to Google in some capacity.

I say it's about time. They've been a little slow to the punch. Here are some sites that have done it already (or some variation of it):
