The Buffalo and Black Rock Railroad was chartered in 1833 and opened in 1834, operating a horse-powered line from downtown Buffalo north to Black Rock, now the east end of the International Bridge. The line was mostly built on state land next to the Erie Canal.
The Buffalo and Niagara Falls Railroad was incorporated in 1834[1] to take over the Buffalo and Black Rock and extend it north and northwest to Niagara Falls. Construction began in August 1836, and included a replacement of the low-quality rails of the horse-drawn line. By 1837 the extension to Tonawanda was completed,[2] and around 1840 the rest of the way to Niagara Falls opened.
In or soon after 1852, the new Erie Street terminal was built in downtown Buffalo, along with a relocation of the tracks near downtown to the west side of the Erie Canal.
In December 1853 the newly formed New York Central Railroad leased the Buffalo and Niagara Falls,[2] which at the time did not connect to any other NYC lines. It was merged into the NYC in 1855.
Between 1948 and 1962, a bypass of Niagara Falls was built. This left the old alignment about halfway from Tonawanda and headed north to the NYC's old Rochester, Lockport and Niagara Falls Railroad, where trains turned west to Niagara Falls. The old alignment was abandoned, and part of it was used in 1970 for the LaSalle Expressway.
