秋念11的博客  
好雨知时节,当春乃发生。 随风潜入夜,润物细无声。野径云俱黑,江船火独明。 晚看红湿处,花重锦官城。

能不能发明不停列车?
   

现在列车越来越厉害,趋势甚至是要抢了飞机的风头。最爽的当然是不停直达列车。但可能只有上海北京才有.


列车按站停确实很合理,聪明,但毕竟每次到站停启,上下可能都是少数人,如此既浪费了能量,更浪费大部分人时间。实在应该发明这样一种列车。这种车永远只有起终点,中间是毫不减速的。但旅客仍然可以在中间站上下,办法是:在快到站时,比如说南京,一节将停的车厢(要在南京下的旅客必须提前进入)脱节停靠,而从南京出发的单节车也可以同时出发接上来。当然,接上的车厢必须有动力。这个拖挂点在尾部可能比较合适。


这样,比如上海到北京,南京如果第一站,则北京乘客坐车头,南京乘客坐车尾巴比较合理。


这种列车轨道要复杂一些,技术要求高一些,然现代技术应该早不在话下了。当然,脱挂操作时速度低一点技术指数要求也会低一点,但如果减速过分,那这种发明本身意义就失去了。


这样,脱,挂各需要一条短道。但来往的两条道是可以考虑共享一段的,而脱,挂二道只需要和这共享道连接,而来往列车就可以共享脱挂二道,甚至月台都是合用,效率甚高。(注意来往列车脱挂方向也是相反的)。


主要问题是要调度好,不能撞车,当然,万一时间冲突,那其中一列车就只能放弃此站脱挂,但也不至于撞车。如果实在为了安全,那就来往各用其两条短道和月台。
