Underground Rail Train. While out to ride the Metropolitan Transportation Authority - MTA NYCT Subway/New York Transit Museum Holiday Train "Nostalgia Special" on Sunday, December 11, 2022, a visit to the Lexington Avenue Line was convenient to check out the rail replacement project around the Brooklyn Bridge/City Hall Loop. Due to this weekend work, these trains would be turning at Bowling Green instead, giving an opportunity to see these R-62As in a few stations that they do not normally visit. This "Contract One" section of the original Interborough Rapid Transit (IRT now A Division) is heavily utilized, and regular preventative maintenance with planned detours helps ensure that there will not be unplanned service disruptions. MTA NYCT Subway R-53 C255 (Fuji Heavy Industries, 1T Crane Car, 1979) carries a car load of stick rail to use during the rail replacement project.
