国际铁路重载运输发展概况

The Development of International Railway Heavy-Duty Transport

目前,世界范围内的货物列车重载运输技术迅速发展,重载运输的国家已经遍及五大洲和几乎所有的铁路大国。重载运输技术已被国际公认是铁路货运发展的方向,重载运输取得的效益已由各国的实际运输业绩所证实。提高轴重是世界各国重载运输一致采用的一项重要举措,长期的运行考核证明这项措施既提高了运输收入,又降低了维修成本。同时,提出进一步强化新技术、新装备的研究开发,推动重载运输取得更大的进展。

Atpresent, the railway heavy-duty transport technology for freighttrains is in a rapid development worldwide. The heavy-duty means is seen in allfive continents and almost all important railway countries. It is widely recognizedthat the heavy-duty transport technology is the developing trend and solid evi-dence for the benefit of heavy-duty transport has been well observed from thepractical data in every country. To increase the axle-load is an important solution,which has been broadly adopted by these countries. The transport income hasbeen improved and the maintenance cost has been cut down during the opera-tion and examination that lasted for a long time. In the meanwhile, the paperstates to further enhance the R&D work of new technology and new equipmentso as to further push forward the development of heavy-duty transport.
