Trumansburg, New York: World's Smallest Railroad Diner (Closed)

Made from the cab of an old locomotive. Outdoor ordering and bench seating was for a lucky few.

Black Diamond Diner.

World's Smallest Railroad Diner

Was there in April 2017, on the way back from hiking, and had two hot dogs + chops and Coke. It was excellent.

Hot Dog Machine.

World's Smallest Railroad Diner

Jerry the owner has bought a new portable hot dog maker that he has sitting on a trailer at his diner. He's currently testing it out. Pretty cool machine. He blew the steam whistle for us while we were there.

The way he talked, it sounded like he may be closing the World's Smallest Railroad Diner. He was talking about just using his new hot dog maker where he can put it away in a building every night.

The Black Diamond Diner is only open in the summers. Cute little diner we spotted on the way home. Great food, plenty of outdoor seating.

The diner is made from the cab of an old locomotive. Black Diamond was the name of a passenger train that used to pass through Trumansburg before the tracks were torn up.
