Nearly 80 percent of the families who lost loved ones in the West Japan Railway Co. train derailment in April and who answered a Kyodo survey give the company's safety improvement measures low marks.
The questionnaire and interview survey, conducted in mid-July, indicates more than half the respondents have not recovered from psychological trauma caused by the accident that killed 107 people, including the driver.
Of the 106 families who lost someone in the crash, 40 families, or 41 individuals, responded to the survey, which was released Sunday.
Seventy-eight percent of the respondents, or 32 individuals, said that they think JR West's new safety measures are "insufficient" or that they "do not expect" the steps to be effective. The new safety measures include an automatic train stop system and looser timetables.
These respondents indicated that the steps are insufficient because they were mapped out before the cause of the accident was fully investigated.
Only 5 percent of the respondents, or two people, said the measures are "sufficient"
Asked about what they want most from JR West, 76 percent said it should develop measures that will prevent similar accidents.
