[1] The NRR was chartered by the New York State Legislature under The General Railroad Law of 1850 (GRL-50) on March 3, 1865 just 37 days prior to the end of the Civil War.
The two railroads promptly solved the route problem, but not before the City of Brooklyn tried to throw a monkey wrench into the whole deal.
The Nassau RR could not obtain consents for the Washington Avenue portion between Myrtle and Atlantic Avenues, and - of course - the emphasis shifted from Flatbush Village as a source of revenue to Grand Army Plaza, which was to be the most public portion of Prospect Park, which was then under construction.
[note 3] The two railroads finally admitted that they had lobbied in Albany for permission to consolidate,[2] and the legislature consented by passing Chapter 576, Laws of 1868, which authorized the consolidation.
The consolidation was consummated on July 31, 1868, and the Brooklyn City, Hunterspoint and Prospect Park Railroad was born.
