Jinshan Railway or Jinshan Line (Chinese: 金山铁路) is a commuter railway line in Shanghai, part of the planned Shanghai Metropolitan Area Intercity Railway. It runs from Shanghai South in Xuhui District via Xinzhuang in Minhang District to Jinshanwei in Jinshan District, crossing the Huangpu River on a dedicated railway bridge. Passengers can transfer to Lines 1, 3, 5 and 15. It was originally built in 1975 as a suburban branch it has since been upgraded into a high-speed commuter rail line which opened on 28 September 2012.
It is the first line to provide "high speed" commuter rail services, with trains travelling up to 160 km/h (99 mph), compared to 30–70 km/h (19–43 mph) for regular metro service, shortening the 56.4 km (35.0 mi) between Jinshan and downtown to 32 minutes travel time for express trains which make no stops, and 60 minutes for other trains, which stop at all stations on the line. The Shanghai-Jinshan line is the first local rail system that supports the public transportation card.
The line was branded as Line 22 before opening. However, there is another line in long-term planning called Line 22, see Line 22 (Shanghai Metro).
At first, the daily passenger flow was just 13,000 people a day, in 2019 has increased to 33,000. More than 60 million people have traveled on the line in the first seven years of operation. Four new trains (CRH6 model) with a larger passenger capacity of 1,950 started operating from 13 December 2019 on the Jinshan Line. The previous model could only take about 600 passengers.
