Beijing No.4 subway line delayed in rush hours

The No. 4 subway line, which runs through Beijing from south to north, resumed operation after a two-hour delay in the rush hours on Friday due to signal problems, subway sources said.

Problems occurred to the signal system between the line's Zhongguancun and Yuanmingyuan stops at around 7 a.m.,which led to its partial closure to ensure the operation of other stretches.

Subway staff solved the signal problem at 8:53 a.m..to make the whole line return to normal.

During the delay, other parts of the busy line were also affected with slow running and longer intervals, causing a jam of passengers in many stations.

A passenger told Xinhua the train he rode only ran two stops in half an hour. Many had to take buses to work instead.
