目前,加拿大铁路可以有效地缩短判别超载、超限货列车物能否通过给定线路所需要的时间。在此之前,超载、超限货物能否通过某条线路,都必须由手工方式核对该线路上的邻近建筑物及桥梁承载极限,这项工作一般需要三天左右。而使用计算机模拟通过系统后, At present, the Canadian Railways can effectively shorten the time required to determine whether overloading or overloading goods can pass through a given line. Prior to this, overloaded and overloaded goods can pass through a certain line, you must manually check the line on the adjacent buildings and bridges load limit, this work generally takes about three days. After using computer simulation through the system,
