Line 105:
Trainset 102 was taken out of service due to the 2004 Tonghe Xincun crash. After replacing car 92113 and changing of the traction systems and motors, trainset 102 renamed separately as '''DC01A''' and backed to service in September 2007.<ref name=":0" /><ref name=":2" /> It also needed to be expanded. Unlike DC01B, the expansion program for 102 is to order a batch of 2 new carriages (14652 and 14663).
Between 2008 to 2009, a contract for DC01 from Shentong Metro includes a third batch of 30 carriages to expand the remaining trains, 111-113 and 115-116. During the expansion, 10 original carriages (93371, 93421, 93431, 93481, 94011, 94061, 94131, 94181, 94191 and 94241) underwent extensive renovation. After that, trains renamed '''DC01C'''.<ref name=":1" />
