Note that this is NOT the original compressor on Low-V #5466. According to youtube user electricrailwayman, this, and 2 of the 4 low-v cars at NYCT were rebuilt with WABCO D-3 compressors for the 1979 Diamond Jubilee. BERA has since replaced the D-3 compressor with this model. Former Westinghouse cars from the mainline Redbird SMEEs were retrofitted with WABCO D-4 compressors after they were rebuilt. WABCO, now WABTEC, still manufactures this model of compressor to this day. ... https://www.youtube.com/watch?v=i4_PJ-aGgnc

April 21 marked the 100th Anniversary of the original stations of the IRT Flushing Line, which were between Queensboro Plaza and 103rd St - Corona Plaza A special museum train of Mainline R33s painted in various color schemes and a pair of World's Fair R36s sporting the redbird paint scheme ran on the 7 line to commemorate the event, between Grand Central to Main St, Flushing, making a single one-way trip, making all local stops. Fun Facts: 103rd St was originally named Alburtis Avenue when the line first opened. The IRT and BMT originally shared trackage on both the Astoria El and the Flushing El, until 1949, when the Astoria El was converted to BMT, and the Flushing Line became strictly IRT. BMT trains were designated as the "9" when running on the Flushing line, and IRT trains were designated as the "8" when running on the Astoria line. All trains running on the two branches were built to IRT specifications. Despite the 7 being an A division route, all communications is done via the B Division's "BMT" channel due to the "IRT" channel being out of range in Queens. The Astoria Line is the Flushing Line's only connection to the rest of the subway system, at Queensboro Plaza, where it is the only station in the system to offer an across-the-platform transfer between two divisions (the 7 being A division and the N/W being B division). ... https://www.youtube.com/watch?v=HHjIKTa-vug
