Line 16 (Shanghai Metro)

Line 16 is a rapid transit line serving the south-eastern suburban areas of Shanghai. The line was formerly known as the Lingang line. It was originally designated as Line 21 and was planned as the south part of line 11. The line runs entirely in Pudong New Area, starting from, via Shanghai Wild Animal Park, Huinan Town, ending at in Nanhui New City. The line is 59 km long and has 13 stations of which three are underground and the rest elevated. Construction begun in early 2009, and the line opened on 29 December 2013. The second phase was completed at the end of 2014.

The design speed of Line 16 is 120 km/h, and the actual maximum operating speed in the above-ground section is about 100 km/h. Line 16 is susceptible to further speed limits due to heavy fog, due to the high operating speed of the line requiring longer sight distances. The line is colored aqua on system maps.

History
The new line was originally designated as Line 21. Shanghai Metro Authorities have since changed this to Line 16, and will integrate into the planned transport hub of Lingang city.

Service routes
Line 16 is the only line in the Shanghai Metro planned to feature different stopping services, with a rapid service stopping only at Longyang Road, Luoshan Road, Xinchang, Huinan, and Dishui Lake stations. Between 30 January 2014 and 21 March 2016, due to insufficient rolling stock and overcrowding of the line, all rapid services were suspended. To further increase capacity, the existing 3-car train sets were to be expanded to full 6-car sets and the rush hour headway was reduced to a minimum of 4 minutes and operated with a mixture of 3-car and 6-car trains. Since 1 October 2018, rapid service trains also stop at Lingang Avenue station at weekends and public holidays. Since 16 November 2018, rapid trains of weekdays stop at Lingang Avenue station. Express and Rapid train services started on 18 June 2020, With express services reducing end to end travel time to 34 minutes and Rapid services reducing end to end travel time to 46 minutes.

Future expansion
The "China (Shanghai) Pilot Free Trade Zone Lingang New Area Territorial and Spatial Master Plan (2019-2035) (Draft for Review)" proposed that in the future, Line 16 will pass through the Dishui Lake and arrive at the future Nanhui New Town hub.

Rolling Stock
Contrary to other A-class trains with 5 doors on each side of a carriage, the Class A trains for Line 16 only have 3 doors due to the line's more suburban nature. The 16A01 trains initially operated in 3 car formations, leading to huge overcrowding issues upon opening. 16A01 primarily have transverse seating to suit its more suburban role. With the introduction of the 16A02 stocks, 16A01 trains now operate in 3+3 car formations. The 16A02 trains have more standing room and use more longitudinal seating, which will be able to take 200 more passengers than the 3+3 formation of 16A01. A six carriage train has a capacity of 2,378 passengers, 120% more than trains with three carriages. The tapering of the carbody between cars 3 and 4 where the "blind" cabs of the 3+3 set would be to match the dynamic envelope of a 3+3 set. 16A02 offer USB charging.
