Metro lines 3, 4 to split by 2015

THE Metro system soon will start the process of separating Line 3 and Line 4, which by 2015 is expected to increase the capacities of the two busiest lines in the city, a senior subway expert said yesterday.

The lines, which currently share part of their routes, will go their separate ways in a rerouting project that will involve 2.6 kilometers of track and cost 2.89 billion yuan (US$467.5 million), according to the National Development and Reform Commission.

"The city should start the project as soon as possible because the sharing on the routes has seriously limited the capacities of the two lines, especially the ring-shape Line 4 that links many other Metro lines of the city," said Sun Zhang, a Metro expert and professor with Tongji University.

Sun made the remarks after a new shuttle bus route meant to relieve crowding on part of Metro Line 3 during the morning was canceled over the weekend after it got light use due to road congestion.

Lines 3 and 4 share nine stations between the Baoshan Road and the Yishan Road stations, forcing passengers have to wait for at least five minutes for either of the lines' trains.

"After the separation, the train intervals of both lines can be shortened to about 2 minutes, doubling the lines' capacities," Zhang said.

According to the plan, Line 4 will run the ring-shape route alone. Line 3 will be cut into two separate parts - Jiangyang Road N. to Shanghai Railway Station in the north and Yishan Road to Shanghai Southern Railway Station in the south.

The Baoshan Road Station where the two lines will still meet after the separation will be renovated, Shanghai Radio Station news reported yesterday. Two new elevated rails will be built at the station for the new Line 3.
