Small train supplies water to mountain for 44 years

The train commutes between the towns of Songshu and Baihe, nestled deep in Changbai Mountain. Since 1975, it has run for more than 1.6 million km, delivering water to over 2,600 nearby villagers that had limited access to clean water.

Though cisterns have been built to store water unloaded from the trains, villagers along the line still keep the tradition of welcoming the train in person, clanking their buckets and bottles.
