Sixth Avenue El demolition at 50th Street, 1939.

Constructed in the 1870s, the Sixth Avenue El was the second elevated line erected in the city (after the Ninth Avenue El). After nearly 60 years of shadowing Sixth Avenue, shaking its adjacent buildings, and dropping all sorts of debris from its tracks, the Sixth Avenue El's death knell was sounded when the city began work on the underground Sixth Avenue Line in 1936. The city purchased the line for $12.5 million and made plans for its demolition. Following a loud and boisterous trip, as passengers stripped the train car for souvenirs, the final IRT Sixth Avenue Elevated train rumbled into the station at 53rd Street and Eighth Avenue at 11:26pm on December 4, 1938. The last passengers made off with destination signs, light bulbs, and straps, all the while smoking cigarettes in flagrant disregard of the printed signage (which was likely stolen too)! The process of razing the elevated structure began in early 1939. The Wurts Brothers captured this crowded process of demolition at 50th Street. The IND Sixth Avenue Line opened in December 1940, two years and one week after the elevated ceased operations.
