NEW YORK (AP) — Happy anniversary, New York City subway!
The Metropolitan Transportation Authority is marking the 115th anniversary of the opening of the first rapid transit subway.
The subway line running along Manhattan's east side connecting City Hall with Harlem opened on Oct. 27, 1904.
That line was owned by a private company. In following years, another private company and a city-owned company also opened subway lines.
The lines came together in what's now the city subway system in 1940.
The MTA is marking the anniversary in a number of ways, including a digital exhibition of photos from the construction of the original subway line.
The photos are being displayed at the subway stations on that line.
