Across China: All aboard the fasting train!

Ma Shemu wipes the floor of the vestibule with paper hand towels, puts down his black jacket, faces West, kneels down on his jacket and prays for 20 minutes.

Ma, from northwest China's Gansu Province, is a member of the Hui ethnic group. As with Muslims everywhere observing the holy month of Ramadan, Ma prays five times a day, even when aboard a train.

The Z917 train from the provincial capital of Lanzhou is speeding Ma to Nyingchi in southwest China's Tibet. He is visiting his son who has been in business there for four years.

To catch the early train, Ma stayed at a relative's home near the station. At 4 a.m. he had beef noodles for "suhur," the meal eaten before daybreak that will sustain him through his day's fast.

Muslims do not eat or drink from dawn to dusk during the holy month, a practice widely observed in China by Hui, Kazakh, Kyrgyz, Tajik, Uygur and Uzbek ethnic minorities, among others.

On the train, Ma makes small talk with another passenger, Su Hebibu, also Hui, from Linxia of Gansu where they boarded the train together.

Su, 35, runs a fruit business in Nagqu, Tibet. He returns home every May or June, when business is quiet. He too is fasting.

"I sometimes feel dizzy and weak during the day, pretty much like the altitude sickness I encountered when I first arrived in Nagqu," Su said.

At 8:45 p.m., Ma takes out tea leaves, pancakes and some salad and begins to prepare "iftar," a most welcome meal taken when the sun finally sets. He bought the salad at a halal noodle stall before getting on the train.

"We usually break our fast at 8:40 p.m. at home, but on the train, I will delay my dinner because of the time difference," he said pointing at the sun, still hovering above the horizon.

At 9 p.m., bidding farewell to some fellow Muslim passengers disembarking at Golmud Station, Ma takes the first swallow of tea before tucking in to the salad and pancakes.

The train, carrying 787 passengers, is running on the Qinghai-Tibet Railway, the world's highest, and a lifeline between Tibet and the rest of China. The line celebrates its 10th anniversary on July 1.

According to chief train conductor Yang Xiaomeng, during Ramadan, most Muslim passengers choose to pray in the restaurant car or vestibules. Many carry their own "sajjada," or prayer mat.

At 4 a.m. the next morning, as the train is arriving at Tanggula, the world's highest railway station, Ma takes his "suhur" once again and begins another long day's fast.

Ma has never taken a plane. The furthest he has ever gone is Lhasa, capital of Tibet, where has been three times by train.

"The railway keeps me close to my son," he says. Endi
