A subway train can take a five- or 16-minute "bath" after a long day's service in Xiamen, East China's Fujian province.
The train will receive such a service at least twice a week according to Xiamen Daily. Work staff will examine conditions every day to make sure the train is clean and tidy, aiming to provide the best experience for passengers.
