You know, 5000 kilowatt-hours of electricity is equivalent to the electricity consumed to fully charge 280000 mobile phones!

While enjoying the comfortable experience brought by high-speed rail, have you found a phenomenon that the lights at the front of the high-speed rail are always on, and the lights in the carriage are always on, no matter day or night

Why is the light inside the car always on?

First of all, let's talk about the carriage. The train passes through different landforms during its journey, sometimes plains, sometimes basins, even hills and mountains. The light changes with the outdoor environment. The outdoor light is relatively dark on the shady slope behind the mountains, and the light is more dazzling in the direct sunlight area.

he lighting in the car during the day is to let you adapt to the strong light changes in the train, so that you can catch up with the drama and enjoy the food on the long way. Isn't this service very good!
