High-speed trains receive thorough clean

          


          


          Automatic cleaning of a high-speed train in Shanghai, Jan 8, 2017. The cleanup uses both automatic and manual efforts that take about 45 minutes for each 400-meter-long train. One group of workers cleans 20 locomotives each night.
