The operator of the Shanghai subway says it uses a signal system produced by a company blamed for a fatal railway crash in July.
The president of the subway operator, Yu Guangyao, spoke to reporters on Tuesday after a rear-end collision injured more than 270 people earlier in the day.
The accident on the Number 10 line may have been caused by a flawed signal system. An automatic braking device had failed to work.
A system failure on the same line caused a train to go in the opposite direction in late July. This was only days after the high-speed railway accident killed 40 people in Zhejiang Province.
Yu said the signal maker assured them the problem would not happen again after making repairs.
Shanghai citizens are posting online messages expressing their concerns over the frequent accidents.
