China in Slow Motion: A Journey on the Green Trains

Learning that I would ride the “green train” to explore the traditional heart of China, my mother bombarded me with advice: “Pack enough clothes. Be wary of pickpockets. Remember to bring toilet paper.” At 68, hailing from chic Shanghai, and a little anxious, she has in mind the journeys of her youth on these noisy trains. The crowded cars, the whistling locomotive, everyone elbowing to preserve their personal space in the smoke-filled air of cigarette smoke…

Forty years later, in Wutai, in Shanxi province (northern China), the mood is quite different in this April when, dressed in her enduring dark green, the train 8817 bound for Taiyuan enters the station. Passengers wait neatly in single file at the door of their car. Only Emeric, the GEO photographer who accompanies me, prowls near the edge of the platform to capture the train’s arrival. The station officer, cap on his head and a small flag in hand, watches him, more tolerant with the foreign visitor than with his fellow countrymen.

In the Bowels of the Country

One only has to gauge how some travelers react to the presence of an Occidental to understand that this China does not share the same openness as the coastal megacities. On the train, as Emeric, stocked with his two backpacks, passes by, children whisper to their parents, adults take his picture… As soon as we are seated, our neighbor greets us. Mr. He, in his fifties, is taking this train to return home to Xinzhou, three hours away. “I organize artistic activities with residents of Wutai County and I go back home once a week”, he explains, noting that he works for a rural revitalization program.

A project of President Xi Jinping. “I am a bit like this train”, he concludes with a smile, pointing to the characters inscribed on the window:

“A slow, not-for-profit train serving rural renewal.”

Getting on a lüpi huoche (“green-skin train”) means boarding with the China of the rural, those small hands that keep the gears turning the world’s second-largest economy. Of the 4.6 billion rail journeys made in 2025 in the country, only 20% were aboard these trains, introduced in 1959, which, for some, race along at the maddening average of… 30 km per hour. In the 1990s, the entire country traveled only with them.

Motion Sickness: This Hidden iPhone Feature Could Change Your Routes

Dizziness, nausea and vomiting, sweating, excessive salivation, headaches — motion sickness can turn a vacation road trip into a real nightmare. More common in children, though it also affects some adults quite severely, motion sickness can strike in a car, on a boat (the famous seasickness), but also on a plane and, though rarer, on a train or even in the subway.

Motion sickness is thought to stem from an inadequate brain response to two conflicting cues: the eyes perceive a stationary environment, while the vestibular system, located in the inner ear, detects the vehicle’s movements. A range of techniques, more or less effective, can help lessen the symptoms. But a solution might lie deep within your iPhone.

Make the body believe it is in motion

Homeopathy, acupressure bracelets, antihistamine medications, choosing the right seat, or simply keeping your gaze fixed on the horizon — all of these tips can help limit motion sickness, provided you avoid reading or watching a moving screen. And yet, as the BBC details, the lead may lie in the little-known functionality of your smartphone that could help you better cope with travel.

Called “Vehicle Motion Indicators”, it displays animated dots along the edges of the screen that move in sync with the vehicle’s movements in which you are traveling. All of this, without interfering with using the phone.

“If you can send signals to your body about how you move through space, this can alleviate motion sickness,” explains to the BBC Kristen Steenerson, a professor at Stanford University in the United States. The vestibular system expert herself uses this feature, praising its effectiveness. “Everyone thinks there’s a problem with my screen, but these dots are really brilliant,” she says enthusiastically.

How to enable this feature on your smartphone?

To test this option, go to the Settings on your iPhone, then choose Accessibility > Movement > Vehicle Motion Indicators. You can opt to keep it enabled permanently or in Automatic mode. In this case, small animated dots appear along the edges of the screen when the phone detects that you are in motion, and disappear when the movement stops. If this feature is currently only available on iPhone, it is possible to download an app that offers a similar result on Android phones.

The BBC journalist collected numerous very positive testimonials, although all pointed to the same paradox: this feature is only useful when you have motion sickness because you’re looking at your phone! Nevertheless, nothing prevents you from turning it on just to try to relieve your motion sickness, even if you hadn’t planned to use your phone during the trip. Or you can also put your phone down… and look at the horizon!
