For residents in Huojugou village in China's Changbai Mountains, a train whistle is a euphonious sound that will bring gurgling water to their kitchen and bathhouse.
For 44 years, the mountainous village and several others in northeast China's Jilin Province have relied on a train, which only has one locomotive and one tank car, to provide their water supply.
