There were no trucks and buses for a long time. Now the Beijing-Guangzhou line is so busy, where is the chance to insert such a train? Baoding is now transported to the urban area by land, and it takes up to one hour by car. It doesn't matter that some train tracks will not be stripped and waste manpower and material resources.
This small train should have been built in the 1960s when the three-proof construction industry entered the mountains. It has been abandoned for many years.
