In fact, it takes more than 10 minutes to walk from one station to another along the mountain trail, and it takes nearly 20 minutes to take the train. So why are these three railway stations so “close”?
China Railway conducted a popular science today: it turns out that this special design is called “exhibition line”.In order to solve the problem of large height difference within a short distance of some railway sections. To put it simply, it means increasing the mileage and reducing the slope. The same is true for the “man”-shaped railway designed by Zhan Tianyou.
According to reports, the height difference between Maocaopao Station and Sanjiazhai Station is 541 meters. When the train passes through this section,Through the Beipanjiang Zhan Line, it circled four times around the three stations of Maocaopao, Duchuanzhai and Sanjiazhai, and extended the railway for 38 kilometers, so as to be able to pass safely and smoothly.
Three stations are set up here, mainly to ensure the safe operation of trains under a certain railway gradient. At the same time, the Shuihong Railway is a single-line electrified railway in the mountainous area. On average, a station is set up every 8 kilometers on the line, which is convenient for trains to stop and meet and receive and dispatch trains. In addition, these stations also greatly facilitate the travel of villagers along the line.
