试验和理论研究结果表明,只在列车头部挂有机车的各种可能的运行工况下,纵向力的安全水平在牵引重量小于8000t的列车中才是有保证的。重载列车的运行安全性只在某些附加条件下才能得到保证。资料表明,如果编组列车将机车沿列车长度配置,并借助无线电操纵司机阀进行同步制动,列车重量实际上可以提高到18000～54000t。同时,这种列车的运行安全性在紧急情况下,即制动主管在最薄弱处发生断裂时仍可得以保证。这是借助于专门装置(包括靠近断裂处机车上的无线电操纵司机阀)来实现的。
The experimental and theoretical results show that the safety of longitudinal forces is only guaranteed in trains with a towing weight of less than 8000t under all possible operating conditions in which locomotives are hung on the train head. The operational safety of heavy-haul trains can only be guaranteed under certain additional conditions. The data show that if the grouping of trains locomotives along the length of the train configuration, and by means of radio control valve driver synchronous braking, the train weight can actually be increased to 18000 ~ 54000t. At the same time, the operational safety of such trains can be guaranteed even in emergency situations where the brake master breaks down at the weakest point. This is done with the aid of special devices, including radio-controlled driver valves on the locomotive near the breakout.
