When new subway lines are built, it is often a struggle to get them to fit into the existing network of lines and stops – in particular in the New York City Subway, which currently has 468 stations. So, sometimes, a station gets abandoned.
This cool website has a list of all the former NYC stations that are now abandoned, with a brief history of each one (including some before and after photos): Abandoned Stations by Joseph Brennan. Here’s a few examples from the site:
Court Street Station, closed in 1946
In Brooklyn Heights, this abandoned station is now the Transit Museum which displays artefacts related to the history of the New York City Subway.
City Hall Station, closed in 1945
The first NYC subway station to open in 1904 was City Hall Station and it was elaborately decorated with high-vaulted, tiled ceilings and skylights. It was closed in 1945. It was supposed to be part of the Transit Museum, but the project fell through. It’s apparently still used by the subway cars as a turnaround at the end of the 6 line, so that at Brooklyn Bridge stop if you are not asked to exit the train, you can ride the car while it turns around in the old station.
Edit: A previous version of this post contained inaccurate information about 76th Street Station which has since been removed.
