“Naoki Sato, an official at Nippon Sharyo, said on Friday that the company’s investigation into the crash had discovered a flaw in the blueprint for wiring the connection of the train’s automatic train protection safety system to the control station.
There is no problem with the safety system itself, which is designed to automatically apply the brakes when the train exceeds the speed limit, the official said.
Nippon Sharyo’s Sato said the flawed blueprint was used in 19 train sets built for Taiwan, including the one that crashed. He said any decision on whether to fix the wiring was up to the Taiwan rail authority, which owns the trains.
The Taiwan Railways Administration said in a statement it has asked Nippon Sharyo for a more detailed explanation. It did not elaborate. It was not immediately clear whether the remaining 18 trains were currently in operation.”
