On June 30, 1924, at what is now the other end of the line, a subway line initially known as the 14th Street–Eastern District Line, usually shortened to 14th Street–Eastern Line, was opened running beneath 14th Street in Manhattan, from Sixth Avenue under the East River and through Williamsburg to Montrose and Bushwick Avenues. In 1924, a temporary connection was built from the Long Island Rail Road's Bushwick Yard that ran via Montrose Avenue and then connected to the BMT Canarsie Line under Bushwick Avenue just near the Montrose Avenue station. This was done in order for the delivery of new BMT Standard subway cars for the then isolated Canarsie Line of the New York City Subway. The first of the cars were delivered by this ramp on June 18, 1924.
