History
A separate entity exclusively for operating long-distance express services was conceived by the Government of Tamil Nadu in 1975, and the services were transferred to the newly formed express wing of Pallavan Transport Corporation with effect from 15 September 1975. It was registered formally on 14 January 1980 and renamed as Thiruvalluvar Transport Corporation (TTC) in honor of the Tamil poet Thiruvalluvar. During the 1990s, JJTC was formed, which operated interstate routes of the erstwhile TTC. JJTC was then renamed as RGTC in 1996. Both TTC and RGTC were later merged into the State Express Transport Corporation (SETC) in 1997.
