Speeding could be the cause of Taiwan's worst train disaster in decades. Sunday's derailment claimed 18 lives and left nearly 200 people injured. Investigators say that the Express train was going too fast when it entered a section of a curved track before it ran off the tracks in Xinma Station, Yilan County. The designated turning speed there is 75 km/h but the train was running over 80 and perhaps even over 100. The investigation continues. The Yilan procuratorial authority has filed a case to detain the driver on suspicion of causing deaths by negligence. Local media reports the driver and the conductor reported brake faults and problems with the power system before the accident happened.
