History
See New York City Subway nomenclature for a complete explanation; this is just a table of when each service has existed (and been signed for the public). Shuttles were SS until 1985, when they became S (which had been used for specials). See here for the colors used for shuttles in 1967; in 1968 all six became green, and in 1979 all shuttles became dark gray.
