The BMT Lexington Avenue Line (also called the Lexington Avenue Elevated) was the first standard elevated railway in Brooklyn, New York, operated in its later days by the Brooklyn Rapid Transit Company, the Brooklyn–Manhattan Transit Corporation, and then the City of New York.

The Brooklyn Elevated Railroad opened the line to passengers at 16:00 on May 13, 1885, with a five-cent fare[2] for trains every five minutes.

After a half day of infrequent service, trains began serving the new station on a regular schedule the next morning.

[7][8][9] Several weeks before the line was completed to Van Siclen Avenue, the western terminal at Fulton Ferry was opened at noon on November 11, 1885.

Thus passengers transferring between the two lines could disembark at Navy Street and simply enter the next train on the other route.

[citation needed] This was the only part of the New York City elevated system to be permanently closed without ever having been electrified.

[28] An extension of the Brooklyn elevated east to Cypress Hills, over Fulton Street and Crescent Street, opened on May 30, 1893, and the Brooklyn Union elevated extended both Lexington Avenue Line and Broadway Line trains to the new terminal.

[31] On April 27, 1950 it was announced that the line would be demolished at the suggestion of the Board of Transportation and the Brooklyn Borough President John Cashmore.

[32] The last Lexington Avenue train ran at 21:00 on October 13, 1950, with a small celebration, 65 years after the line opened.

Transportation Commissioner G. Joseph Minetti joked that "if we had this many passengers riding regularly we wouldn't have to shut it down.

[32] The original service pattern was a single line from Fulton Ferry to East New York.

[35][36] Lexington Avenue trains were extended from Sands Street over the Brooklyn Bridge to Park Row in June 1898.

Trains began at either Park Row in Lower Manhattan or Sands Street in Downtown Brooklyn, and ran along the Broadway elevated at least to East New York and sometimes to Jamaica.
