The underground system with the most stations is the New York City subway, with 468 stations (277 of which are underground) in a network which covers 370 km (230 miles). It serves an estimated 4.5 million passengers per day. Although the routes covered by the subway measure 370km (230 miles), the system has a total of 1,355km (842 miles) of track, including 299km (186 miles) in yards, shops and storage areas. Officially opened on October 27, 1904 with 28 stations, most of the existing network had been completed by 1940. In addition to the 277 stations situated underground, 153 rest on elevated structures, 29 are built on embankments and nine lie in 'open cuts' (trench-like depressions below street level). The Smith and 9th Street station in Booklyn is the highest at 27m (88ft), whilst Manhattan's 191st Street station is the deepest at 55m (180ft). During weekday rush hours 547 trains consume 495,000 kW of power, supplied by 214 electrical sub-stations. Operating 24 hours per day, seven days per week throughout Manhattan, Queens, Brooklyn and the Bronx, trains on the system cover around 1.6 million kilometers (1 million miles) on an average weekday.
