Nassau Electric Railroad

The Nassua Electric Railroad was a short-lived trolley line operating in Brooklyn, New York. The name refers to the older name for Long Island which was Nassua Island. It was incorporated on March 13, 1893, by Patrick H. Flynn and became known locally as "Flynn's road." Prior to incorporation, Flynn secured franchises in many Kings County towns under a variety of operating and construction companies. He later consolidated those companies into NER. The line ran along Ocean Avenue from near Coney Island to central Brooklyn.

Flynn was a Brooklyn real estate developer who grew frustrated at the slow pace of street railway development in and around Brooklyn. He began promoting street railway lines that would connect Brooklyn with other towns on Long Island. In the promotion and construction of these lines, Flynn was often in court litigating or defending the legitimacy of his franchises or routes.

NER quickly earned a reputation as a passenger-friendly road. It charged a five-cent fare and free transfers to anywhere on its system. These policies were extremely competitive and forced other lines, including excursion railroads, to lower fares or offer free transfers.

By 1896, Flynn was buying up his competitors, the Atlantic Avenue Railroad, and the Brooklyn, Bath, and West End Railroad.

By 1899, Flynn was loosing control of the company to a railway syndicate controlled by Tom L. Johnson. In January, the Johnson syndicate leased the line to the Brooklyn Heights Railroad (also controlled by the Johnson syndicate) for 999 years, a move vigorously opposed by Flynn who was then without a controlling interest in the company and was powerless to stop it. By the end of the year, the NER ceased to exist as an independent entity.
