West Japan Railway Co. will ease disciplinary measures for train crews to prevent them from covering up errors, company officials said Friday, in what is the first such attempt in the industry.

In the wake of the deadly 2005 derailment near Osaka, the company, commonly known as JR West, will cease reprimanding crews for their mistakes in the hope that the new system will help it quickly identify accidents and faults, the officials said.

In the aviation sector, Japan Airlines Co. and All Nippon Airways Co. have already introduced similar rules.
