T is a service designation of the New York City Subway. It is not currently in use, but was previously used for a service on the BMT West End Line, originally BMT 3. It was discontinued in 1967, but a shuttle, designated TT, continued into 1968. This shuttle was replaced by the B, which in 2001 became the W. Since Sixth Avenue Express service was suspended, Broadway service replaced it. The W ran to Coney Island, and in 2004, was replaced by the D.
