The 7 Train runs 8 miles (12.87 km) between Flushing Main Street, Queens and Times Square, Manhattan, NY on some of the most ethnically diverse strenches of road in the world. This subway/elevated rail route is a vital transportation artery for the borough of Queens. The current 7 Train is a direct descendent of the IRT Queensborough subway, which opened in 1916 and was the second rail tunnel to link Long Island with Manhattan (after the Pennsylvania Railroad's 1910 tubes). The IRT Queensboro route was extended into Queens and by 1928 reached its present Flushing terminal at Main Street. (See History for more info).
Noted as the "International Express", the 7 serves communities with ethnic groups from over 100 countries. For example, Chinese and Koreans cluster in Flushing, at the 7's north end, Hispanics in Corona, Indians and Pakistanis in Jackson Heights and Irish in Woodside and Sunnyside.
Rolling stock is also one thing the 7 train is noted for. The 1964 R36 cars, built for the New York World's Fair at Flushing Meadows of that year have become synonymous with the 7 and Queens in general. However, the 1986-vintage R62As have replaced the R36 "Redbirds" by 2004.
Shea Stadium and the US Tennis Center (home of the US Open) are both located on the 7, at the Willets Point-Shea Stadium station. The 7 is the only train on the world that can lay claim to fame as both the official train of the New York Mets and US Open. Several R36 and R33 WF cars have worn Mets and US Open logos.
The 7 currently is one of the most heavily used NYCT subway routes, with peak hour service every 2-4 minutes (with express service to Manhattan AM, from Manhattan PM), 4-5 weekday midday, 6-12 evenings, 5-8 Saturdays, and 6-12 Sundays. Overnight (12 Midnight-6 AM) service is every 20 minutes. For full service information, see the official 7 Train timetable.
