The PATH train in New York City that connects NY and NJ by underwater tunnel turns 100 today. The New York Times has a slideshow of images detailing the history of the former Hudson & Manhattan (H&M) Railroad Company, known since 1962 as PATH (Port Authority Trans-Hudson).

To celebrate, the PATH train is FREE today from 6AM to 11PM.

Coincidentally, I posted the New York Times front page 100 years ago and one of the front-page news stories was the opening of the “trolley tunnel” to New Jersey (read the original PDF news article from 1908 [pdf]). I’m really loving this TimesMachine thing! It’s so nice to read old news stories exactly how they were printed.
