The New York and Stamford Railway was a streetcar line that connected the Westchester County suburbs of New Rochelle, Larchmont, Mamaroneck, Harrison, Rye, and Port Chester, with the Connecticut suburbs of Greenwich and Stamford. The company was formed in 1901 when the New York, New Haven and Hartford Railroad combined the Larchmont Horse Railway Company with the Port Chester Street Railroad Company. The Larchmont Horse Railway Company was founded in 1888 by the Larchmont Manor Company to construct a line from the New York, New Haven and Hartford Railroad Larchmont train station to its development 1.2 miles from town. The line was rebuilt for electric operation and extended to Harrison in 1901. The Port Chester Street Railroad opened in 1898 serving Port Chester, New York. The trolley line was soon extended west through Rye to Harrison in 1901. The two companies were merged that summer to form the New York and Stamford Railway. Trackage rights over the Westchester Electric Railroad were obtained for access to New Rochelle.
