美国堪萨斯城南方铁路公司(KCS)在对其已使用半个世纪的德拉马斯编组场进行扩能改造中,采用了“设计-施工”的理念和提高编组场效率的创新措施。扩能改造工程的设计目标是使编组场的生产能力达到最大。除采用独特的线路设计以提高编组场的编组能力外,还将原有的切点式减速顶更换为能够连续精确控制速度的活塞减速顶,并在峰顶设置了可以从最高点就开始对溜放速度进行控制的轨道衡。
In its capacity expansion of its half-century Delaware assembly site, the KCS Southern Company (KCS) has adopted the concept of “design-construction” and innovative measures to improve the efficiency of the assembly yard. The design goal of the expansion project is to maximize the production capacity of the yard. In addition to using a unique circuit design to improve the ability of the marshalling yard grouping, but also the original pointcut decelerator to replace the continuous precise control of the speed of the piston decelerating top, and set at the peak from the highest point on the right Sliding speed control of the track balance.
