The Ninth and Sixth Avenue Elevated trains, constructed in the second half of the 19th century, were built as an answer to the city's growing congestion problem. By the 1940s the Els were outdated and inefficient in comparison to the newly constructed modern subways. Between 1939 and 1958 (largely though in 1939 and 1940) the massive steel structures were dismantled piece by piece.

This series is the complete line of the Ninth Avenue El as it existed between the 1870s and 1940.

Completed in 1873, the 23rd Station was originally the penultimate stop for uptown service on the Ninth Avenue El. The station included two side platforms for local trains, and was bypassed by express service via single central track, added in 1916. The station closed and was permanently dismantled in 1940. In the background, the signature facade piers and front gardens of the original London Terrace complex are visible. The unified full-block development of Greek Revival townhouses stood until 1929, when they were replaced with the high rise apartment complex of the same name.

By Lawrence Stelter Since the beginning of European colonization, the trade of goods and ideas created prosperity throughout the area around New York Bay. Industrialization further fueled growth and expansion, sometimes at exponential levels. As the population spread out, people worked, worshipped and took their recreation in places far from where they lived. Thus public transportation developed and inexorably grew. In 1832 the horse-drawn coach appeared, and soon thereafter came the horse car, which ran on rails. After the Civil War the horse-car network became inadequate to serve a population that was approaching one million. City leaders sought a means of transportation that would be separate from and unimpeded by the congested streets. Read this in its original format here.
