at Port Morris itself across the river from North Brother Island. After the construction of the Oak Point Link at the Bronx's southern tip and its subsequent opening in 1998, trains stopped operating along the Port Morris Branch in 1999. Formal abandonment was declared in 2003, when CSX Transportation declared that the branch could be vacated due to the lack of use in the preceding two years. Rolling stock On the electrified portions of the line, M3As and M7As are usually used. As with the Hudson Line, diesel-powered trains are operated by dual-mode Genesis and BL20-GH locomotives, paired with Shoreliner coaches. While some peak-period trains operate directly to and from Grand Central Terminal, most Harlem Line diesel-only territory is operated as shuttle service between Southeast (where electrification ends) and Wassaic, north in Dutchess County. Stations Lake Mahopac Branch Built by the New York and Mahopac Railroad in 1871, the Lake Mahopac Branch diverges from the Harlem Line north of Goldens Bridge and merged with the now-defunct Putnam Division south of Mahopac. Known to some residents of Mahopac as the “Golden’s Bridge Branch”. The entire branch was abandoned on April 2, 1959. Port Morris Branch The entire line was used exclusively for freight. It diverged from the Harlem Line at Melrose and terminated at Port Morris, east of the Oak Point Yard. The line was formally abandoned in 2004.
