On May 3, 1967, Rockefeller signed a bill that allowed the MCTA to oversee the mass transit policies of New York City-area transit systems. The unification agreement would take place the following March, upon which the MCTA would take over the operations of the LIRR, NYCTA, TBTA, New Haven commuter services, New York Central commuter services, and the Staten Island Railway. Initially, the TBTA was resistant to the MCTA's efforts to acquire it. Moses was afraid that the enlarged MCTA would "undermine, destroy or tarnish" the integrity of the TBTA, One source of contention was Rockefeller's proposal to use TBTA tolls in order to subsidize the cheap fares of the NYCTA, since Moses strongly opposed any use of TBTA tolls by outside agencies. In February 1968, Moses finally acquiesced to the MCTA's merger proposal. New York Central and the PRR also merged in February 1968, forming the Penn Central Transportation Company.
