==Platform lengths==
The IND was built with longer platforms than those of the IRT or BMT.  Initial plans called for stations to be built with {{convert|660|ft|m|0}} long platforms to accommodate trains of eleven {{convert|60|ft|m|1|adj=on}} cars. These lengths were shortened, as stations on the [[IND Eighth Avenue Line]] between [[72nd Street (IND Eighth Avenue Line)|72nd Street]] and [[163rd Street – Amsterdam Avenue (IND Eighth Avenue Line)|163rd Street – Amsterdam Avenue]] have lengths of exactly {{convert|600|ft|m|0}}. There were two exceptions: [[96th Street (IND Eighth Avenue Line)|96th Street]] was {{convert|615|ft|m|0}} on both levels, as that was the standard length of platforms built for the IND after the 1940s.<ref name="nycsubway.org"/>

The [[81st Street–Museum of Natural History (IND Eighth Avenue Line)|81st Street–Museum of Natural History]] station had an uptown platform that was {{convert|630|ft|m|0}} long, and a downtown platform that was {{convert|615|ft|m|0}}. Platforms of exactly {{convert|600|ft|m|0}} length can be found on some [[IND Queens Boulevard Line]] stations between [[Elmhurst Avenue (IND Queens Boulevard Line)|Elmhurst Avenue]] and [[67th Avenue (IND Queens Boulevard Line)|67th Avenue]].<ref name="nycsubway.org"/>

Some of the [[IND Sixth Avenue Line]] stations have much greater platform lengths. In [[34th Street–Herald Square (New York City Subway)|34th Street–Herald Square]], the uptown platform was originally {{convert|745|ft|m|0}}, long enough to hold a 12-car train of {{convert|60|ft|m|1|adj=on}} cars. The downtown platform was originally {{convert|685|ft|m|0}}. Both platforms of the [[23rd Street (IND Sixth Avenue Line)|23rd Street]] station are {{convert|670|ft|m|0}}. The [[47th–50th Streets–Rockefeller Center (IND Sixth Avenue Line)|47th–50th Streets–Rockefeller Center]] station has platforms that are {{convert|665|ft|m|0}}.<ref name="nycsubway.org"/>

In the [[IND Second System]], planned stations would have been {{convert|700|to|720|ft|m|0}} long and tile work would have been more "modern".<ref name="nycsubway.org"/>
