Martinsville, NY is village in Niagara County north and east of North Tonawanda, NY. It was a station on the Erie Railroad‘s Lockport Branch.
In 1898 the Erie Lockport Branch was leased by the Buffalo and Lockport Railway, an electric railroad. This railroad was later merged into the Buffalo, Lockport and Olcott Beach Railway, Buffalo & Niagara Electric Street Railway, and International Railway Company.
An Erie Railroad valuation map shows the station in Martinsville was located on the north side of the tracks just west of the crossing with Sawyers Creek Road. I think that Sawyers Creek Road is now Niagara Falls Boulevard, but I am not sure.
