service along the Hudson line until it was folded into Conrail on April 1, 1976. Conrail continued to operate commuter service to Poughkeepsie & freight service north of Poughkeepsie (while, Amtrak's Empire Service continued to Albany and beyond). On July 1, 1973, along with several other stations in Penn Central's Metropolitan Region, the 138th Street, Oscawana and Manitou stops were closed. Manitou reopened in 1983. On September 10, 1974, the MTA announced that work would start on the construction of high-level platforms at eleven stations in the Bronx and Manhattan including at the Marble Hill, Spuyten Duyvil, University Heights, Morris Heights and Riverdale stations on the Hudson Line. The entire project cost $2.8 million. The work was expected to be completed in the late summer of 1975. As part of the work, the University Heights, Morris Heights and Marble Hill stations had island platforms installed, while side platforms were installed at Riverdale and Spuyten Duyvil. All of the platforms on the Hudson Line were -long with the exception of a -long side platform at Spuyten Duyvil and a -long platform at Morris Heights, which was set to be lengthened at a later date. The abandoned station building at University Heights was removed as part of the project. High-level platforms at Spuyten Duyvil and Riverdale were completed in early 1975. On May 2, 1975, the new platforms on the Hudson Line were formally put into service. The completion was marked with a ceremony with the head of the MTA, David Yunich present. The completion of these five stations marked the completion of a $22.8 million project to install high-level platforms at 43 Penn Central stations. The high-level platforms allowed the new Metropolitan and Cosmopolitan to use the stations. During the late 1970s, the Hudson Line's former northbound express track between Spuyten Duyvil and its merger with the Harlem Line was removed. The stations along the line between Spuyten Duyvil and Yankees–East 153rd Street were rebuilt on top of this track's roadbed. Metro-North In 1983, the MTA Metro-North Railroad took control of all commuter operations in the Hudson Valley. As part of the MTA's five-year capital program in 1982, the MTA planned to remove one of the four tracks on the line. The MTA expected that the change would provide more flexible train service as the line would have received a computerized system capable of running trains in either direction on the
