A high-speed train with a speed of 350 kilometers per hour consumes 9,600 kilowatt-hours of electricity per hour. A high-speed train with a speed of 250 kilometers per hour consumes 4,800 kilowatt-hours of electricity. A high-speed train with a speed of 250 kilometers per hour from Nanjing to Suzhou requires nearly 5,000 kilowatt-hours of electricity! You know, 5,000 kilowatt-hours. This is equivalent to the energy consumed to fully charge 280,000 mobile phones!
While enjoying the comfortable experience brought by high-speed rail, have you noticed a phenomenon? No matter it is day or night, the headlight of the high-speed rail is always on, and the interior of the carriage is always brightly lit.
At this time, some people raised questions, why turn on the lights in broad daylight? Doesn't this waste electricity?
Why are the lights inside the car always on?
Let's talk about the carriage first. The train travels through different terrains, sometimes plains, sometimes basins, and even hills and mountains. The light will also change with the outdoor environment. On the shady slopes of the mountains, the outdoor light is relatively dark. The light in direct sunlight areas is more dazzling.
The lights in the carriage are turned on during the day to allow everyone to adapt to the strong light changes in the train, making it easier for everyone to catch up on dramas and enjoy delicious food on the long journey.
The lights in the carriage will be automatically adjusted according to outdoor conditions. At the same time, the lights at the top of the corridor, brightness level, and light temperature can all be adjusted freely.
