Just Your Average 30 Car Train. On the early morning of Sunday, November 13, 2022, Track "M" on the 1/Broadway Line was occupied with overnight layovers of Metropolitan Transportation Authority - MTA NYCT Subway R-62A equipment (Bombardier, 1982-1985) that were beginning to enter service, but it certainly gives the appearance of one very, very long train. All A Division/IRT (Interboro Rapid Transit) trains use 10-car trains except for the Grand Central Shuttle (6-car) and the 7/Flushing Line (11-car).
