in eastern New Haven and East Haven, where the old alignment took it across many streets at-grade. The new line ran further east, requiring a tunnel to pass under the hills to merge with the NYNH&H main line at Air Line Junction, also the junction with the Boston and New York Air-Line Railroad. Other realignments include a section in Branford, where the old alignment is still partially in use to access the Branford Steam Railroad, as well as smaller sections in Old Lyme and just east of Rocky Neck State Park in Niantic. The Shore Line Railway was merged into the New York, New Haven and Hartford Railroad on March 17, 1897, becoming its Shore Line Division. In 1969 the New Haven merged into Penn Central, and then at the latest the Shore Line was extended along the whole New York City-Boston route. In 1976, Penn Central merged into Conrail, and Amtrak bought much of the Shore Line, now known as the Northeast Corridor, including the former Shore Line Railway. Shore Line East now provides commuter rail service between New Haven and New London, connecting at New Haven to Metro-North's New Haven Line for continuing service to New York City.
