New York Subway Begins Service

New York City's first underground rapid transit line opened between City Hall and 145th Street, using electric multiple-unit trains designed by Frank J. Sprague. This innovation alleviated severe street congestion in the growing metropolis and set standards for urban rail systems worldwide. Mayor George B. McClellan operated the inaugural train. The project involved massive tunneling under busy streets and introduced the now-iconic IRT system. Its success influenced subway construction globally and supported New York's emergence as a world financial capital.
