Operating between Guiyang and the province's Yuping Dong autonomous county in Tongren since 1997, it is one of the few remaining green train routes in the country, with most having been replaced by high-speed railways.

Despite the slow speed, for villagers along the route, the train represents not only a means of visiting friends and relatives, but is also a vital link for transporting agricultural products to markets beyond the mountains.

Starting Jan 26, the beginning of this year's Spring Festival travel season, local authorities decided to turn the train into a brand by integrating agricultural, cultural, sports, tourism and commercial experiences along its 337-kilometer route.
