The West Shore Railroad was the final name of a railroad that ran from Weehawken, New Jersey, on the west bank of the Hudson River opposite New York City, north to Albany, New York, and then west to Buffalo. It was organized as a competitor to the New York Central and Hudson River Railroad, but was soon taken over by that company.
