CITY Metro authorities said yesterday that they have teamed up with the Shanghai-based military technology institute to develop a sonar system that can be rigged to the subway train's front and rear to prevent accidents if signal facilities break down.
The move is among a slew of safety measure taken in the wake of the two-train collision on Metro Line 10 last year in which hundreds of passengers were injured.
Yu Guangyao, president of the Shanghai Shentong Metro Group, the Metro operator, said the sonar has been put for testing on a city subway line, which will help Metro staff locate trains riding in the same tunnel.
Yu said the system has been found to be helpful in train dispatch especially "when the signal control system suffers glitches under emergency."
Yu apologized in a press release hours after the Line 10 collision on September 27 last year.
Human error was blamed for the accident in which Metro staff used manual dispatch procedures following a signal failure due to power cut but failed to strictly comply with management regulations. Shentong said it has learnt lessons from the accident.
