Line 4 (Shanghai Metro)

Line 4 is a loop line of the Shanghai Metro network. Its rolling stock carry a bright violet colour belt to differentiate them from Line 3 trains which share a portion of its track. To determine the direction of travel, the line that travels counter-clockwise is called the Outer Loop (外环), while the other line is known as the Inner Loop (内环). Although it is a loop line, trains returning to the depot use Yishan Road as a terminal to let all passengers disembark. The first segment of the line between Damuqiao Road and Lancun Road (running in a "C"-shape) opened on December 31, 2005. The remainder of the line opened on December 29, 2007. The line is colored purple on system maps.

Type A	2014–2015	04A02	27	Tc＋Mp＋M＋M＋Mp＋Tc	Manufactured by Alstom and CNR Changchun; runs both on Lines 3 and 4

Notes

1. Out of system transfer with Line 1.
2. There are two stations named Pudian Road that are about 200 meters apart, one for Line 6 and one for Line 4. Free transfers between the two stations are physically not possible since both are distinct stations located along different parts of Pudian Road. A transfer between the two stations requires users to leave the fare paid area and cross an underground supermarket. This transfer will be counted as two separate journeys requiring two fares.
