The first regularly operated subway in New York City was opened on October 27, 1904, and was operated by the Interborough Rapid Transit Company (IRT). The early IRT system consisted of a single trunk line below 96th Street in Manhattan, with three northern branches in Upper Manhattan and the Bronx, and a southern branch to Brooklyn. The system had four tracks between Brooklyn Bridge–City Hall and 96th Street, allowing for local and express service. Planning for the subway started in 1894 with the enactment of the Rapid Transit Act. The plans were drawn up by a team of engineers led by William Barclay Parsons, chief engineer of the Rapid Transit Commission. Heins & LaFarge designed elaborate decorative elements for the early system. The city government started construction on the first IRT subway in 1900, leasing it to the IRT for operation under Contracts 1 and 2. After the initial line was opened, several modifications and extensions were made in the 1900s and 1910s. In 1918, a new "H" system was placed in service as part of the Dual Contracts, splitting the original line into several segments. Most of the original IRT remains intact and operates as part of the New York City Subway; however, several stations were subsequently closed.
