Airport link line (Shanghai Suburban Railway)

Airport link line of Shanghai Suburban Railway is a commuter rail line currently under construction in Shanghai. It runs from Hongqiao railway station in Minhang District to Shanghai East railway station in Pudong. The 68.6-kilometer (42.6 mi) express line is expected to shorten the travel time between the airports of Hongqiao and Pudong from 90 minutes (by Metro Line 2) to under 40 minutes. Construction started in June 2019. The line is expected to open at the end of 2024.

Description

The line leads from the Hongqiao hub, heads south along the east side of the Shanghai-Hangzhou Passenger Dedicated Line, crosses the Shanghai-Hangzhou Railway Passage, and then turns to the east and travels along Chunshentang, 1.6 kilometers (0.99 mi) south of S20, after crossing the Huangpu River. Walk on the south side of S20 and S1, pass through Pudong International Airport, and then follow the north side of S32 into Shanghai East railway station. The line is 68.6 kilometers (42.6 mi) long, of which, the elevated section is 4.313 kilometers (2.680 mi), the at-grade section is 2.578 kilometers (1.602 mi), and the underground section is 60.448 kilometers (37.561 mi). The project is divided into east and west construction. The west section is located in Minhang District, starting from Hongqiao Hub in the west and ending at the east end well of Huajing station in the east. It has a total investment of 9.549 billion yuan.

It will use a large tunnel boring machine for construction, developed by Shanghai Tunnel Engineering Co. The shield, named Qiyue, or "swift horse", weighs around 3,200 tons and is 99 meters (325 ft) long. It has 14-meter (46 ft) diameter blades, whereas normal blades used to dig the city's metro lines are 6.9 meters (23 ft). It can dig and push 60 millimeters per minute (12 ft/h) underground.

Operation

A rail transit style operation is adopted, with the platform design, train schedule, and other aspects being similar to metro lines. Citizens can use public transportation cards to enter and exit the station. Pudong International Airport and Resort station and the termini have a reserved length for 16-car CRH6F trains while other stations will accommodate 8-car Class C (Express train) stocks.

Proposed Stations

Service routes

T - Through line: Hongqiao railway station ↔ Pudong International Airport T3 (through operation on Lianggang Express )

Through operations

Through operations from Hongqiao Railway Station to Chengbei Road on the Jiamin are scheduled.
Through operations from Pudong International Airport T3 to Lingang on the Lianggang Express are scheduled.

Important stations

In terms of operation mode, a rail transit-style bus operation is adopted. The platform design, train schedule, and other aspects are similar to subways, and citizens can use the Shanghai public transport card to enter and exit the station.

Approximately 88 percent of the line will run underground while the remaining sections will be elevated. The above-ground section is between Qibao and Huajing stations. There are 7 underground stations and 2 above-ground stations. It will use EMU trains with a maximum operating speed of 160 km/h (99 mph).
