The trains are clean. The stations are clean. However, the sewage systems are overwhelmed by the sheer number of passengers.

Toilets in China's 42000 km HSR network,the top pick for intercity travel, are "clean, spacious & often with other amenities" but underestimated passenger flows. Ind Rlys is also grappling with this but slower trains is a plus, for oncehttps://t.co/bUKKAuoFzt

China’s high-speed trains are overwhelmed by poop, study says
Researchers find levels of human waste compounds are hundreds or even thousands of times higher at railway stations than rest of urban sewage system As scientists race to develop new technology to prevent ‘system meltdown’, bacteria-based method might offer answers
The explosive growth of high-speed rail in China has brought a boom in human waste on trains, threatening a meltdown for the railway network’s sewage treatment facilities, according to researchers commissioned by the government to solve the crisis.
“The processing capabilities of waste treatment facilities are declining, some of them already out of service,” said the team led by senior engineer Xin Siyuan with the China State Railway Group in a peer-reviewed paper published in journal Railway Standard Design on May 24.
Xin’s team said that after spending a year closely monitoring the waste water quality at a major high-speed rail station in Beijing, they were deeply worried about the results.
