由于专用线(专用铁道)上装载加固不良造成脱轨颠复行车重大、大事故的问题已成为全路行车安全中的突出问题。严格把好专用线装车关是确保行车安全的关键,西安东站取得一万二千九百多天无货运责任行车重大事故的好成绩,这方面的经验是值得推广借鉴的。 As the special line (dedicated railways) on the poor loading and unloading caused by derailment reversing traffic heavy, the problem of major accidents has become a prominent issue in the road traffic safety. To strictly control the loading and unloading of special lines is the key to ensure traffic safety. Xi’an East Railway Station achieved a total score of 12,900 days without any responsibility for carrying heavy-duty freight vehicles. This experience is worthy of reference.
