bold effort necessary step to relieve system-wide congestion and increase train frequencies, Shanghai Metro is planning to split overlapping lines 3 and 4 tracks by 2015.
Lines 3 and 4 currently share tracks between Baoshan Road and Yishan Road stations – a total of ten stations. Shanghai Shentong Metro Group hopes that splitting the two lines will allow it to increase frequencies of both lines and prevent something horrific like this from happening everyday.
The main component of the 2.89 billion yuan project involves constructing a 2.6 kilometer branch line between Shanghai Railway Station and Baoshan Road Station. Lines 3 and 4 will still meet at Baoshan Road Station following the re-routing project.
After the project’s completion in 2015, line 4 will exclusively service most of the shared tracks while line 3 will be split into two disjoined sections: northern (from Shanghai Railway Station to North Jiangyang Road Station) and southern (Yishan Road to Shanghai South Railway Station).
Line 4, also known as the “loop line,” is an important transfer line for passengers getting from one part of the city to another. As of writing (because Shanghai has one of the fastest growing rapid transit networks in the world), line 4 provides at least one interchange to every line in the Shanghai Metro system besides line 5.
Line 3, on the other hand, is one of the busiest and oldest lines in the system.
Last month, the metro authority began a two-year “frame repair” maintenance project on all line 3 and 4 trains that has resulted in limited capacity on both lines. At the same time, the metro system registered a daily ridership record of 8.486 million passengers on March 9.
