open in the coming fall. Work on the station was 65 percent complete as of that month. On July 18, 1910, several tons of rail fell through the roof of the tunnel onto the northbound track after an overcharge of powder was set off, nearly seriously injuring a dozen workers. The accident delayed service for two hours. Although not fully completed, the 191st Street station opened to the public on January 14, 1911. The ticket booths, which were to be in vestibules at street level, had not been finished, and temporary booths for the sale of tickets were built and put in the mezzanine. A special train with guests, including top IRT officials and Henry Morgenthau, ran from 137th Street to the station. Initially, the station was served by West Side local and express trains. Express trains began at South Ferry in Manhattan or Atlantic Avenue in Brooklyn, and ended at 242nd Street in the Bronx. Local trains ran from City Hall to 242nd Street during rush hours, continuing south from City Hall to South Ferry at other times. In 1918, the Broadway–Seventh Avenue Line opened south of Times Square–42nd Street, thereby dividing the original line into an "H"-shaped system. The original West Side Line thus became part of the Broadway–Seventh Avenue Line. Local trains were sent to South Ferry, while express trains used the new Clark Street Tunnel to Brooklyn. By the time the station opened, several apartment buildings had been completed, though some lots still remained available for development. In the words of The New York Times, "prior to the opening of the 191st Street subway station ... no high-class residential building was to be found north of 187th Street." The newspaper expected the Fort George area to become one of the "choicest" apartment areas of the city. In January and February 1912, work was completed on the station finish, and a small amount of work was done toward the completion of the elevators. Construction of the station cost $381,000 and was done as a modification to Contract 1 between New York City and the IRT for the construction of the first subway. Space for four elevators in one shaft was included in the station going down to the mezzanine, however, only two of the elevators were installed. The remaining elevators were to be added once ridership at the station justified it. These elevators rise to the surface
