本文简要介绍了运行于加拿大西部加拿大太平洋铁路运煤专线上第一代单元列车的装备,即采用的浴盆式敞车技术和机车无线电控制技术,这一系统几乎无改变地运行了近20年。加拿大太平洋铁路发展了第二代单元列车,其目的是大大地改进列车操纵技术,减少列车设备和线路的维修量。这个多年的发展规划已进入最后阶段,期望在1989年初在运煤专线上开行第一列第二代单元列车。第二代单元列车系统既能体现固定编组列车高运行效率的优点,又不需要更新机车车辆设备。相反,该系统是在改进和加强现有机车车辆,大量采用成熟技术,如导向式转向架、改进的机车无线电控制技术和发展一些新枝术如车辆无间隙连接装置和机车分散布置枝术的基础上发展起来的。今后的第二代单元列车还将使用分立的多路机车远控技术而使列车冲动进一步降低,并使列车运行能耗达到最优值。文中还介绍了有关第二代单元列车设备研制及试验中的性能数据和第二代单元列车系统的组成。
This article gives a brief overview of the first generation unit trains running on the Pacific Railroad coal transportation line in Canada’s western Canada, the bathtub gondola and the locomotive radio control technology. The system has been running almost unchanged for almost 20 years. The Pacific Railroad of Canada developed the second generation unit train, which aims to greatly improve the train control technology and reduce the maintenance of train equipment and lines. This multi-year development plan has entered its final phase and expects to launch the first generation of second-generation unit trains on the coal feeder in early 1989. The second-generation unit train system not only reflects the advantages of high-efficiency train operation, but also does not need to update the rolling stock equipment. Instead, the system is based on improvements and enhancements of existing rolling stock, extensive use of proven technologies such as guided bogies, improved locomotive radio control technology and the development of new technologies such as vehicle gapless linkages and locomotive decentralized deployment On the development. In the future, the second-generation unit train will further reduce the train impulse by using the separate multiple-locomotive remote control technology and achieve the optimal energy consumption of the train operation. The article also introduced the second generation unit train equipment research and test performance data and the second generation unit train system.
