tokio - The Japanese manufacturer of the train that derailed in Taiwan said that a design error was discovered on the train. Due to the error, which probably lay in the wiring, the central control system was not alerted after an automatic safety function was disabled by the operator.
The train driver knew in a Taiwanese court that he had disabled the speed control system himself. An employee of train builder Nippon Sharyo said that there is no problem with the automatic safety system itself. That system is designed to automatically brake when the train exceeds the speed limit.
