'Toilet revolution' right on track

GUANGZHOU - Janitor Huang Xueying has nine cleaning rags, two different colored mops, and several bottles of detergent, among other custodial supplies. "Colors are used to distinguish tools used for different purposes," he said. "The blue rag is for toilet seats, and the white for mirrors."

Huang, 43, works on the G79 high-speed train between Beijing and the southern city of Guangzhou, Guangdong province. The train is among thousands running during the Spring Festival travel rush, which began on Feb 1.

Around 390 million passenger trips are expected to be made during the 40 day travel frenzy, up by 8.8 percent compared with last year.
