Is it safe to travel by EMU?

[EverlyDella]

Although there are currently mutations in the epidemic, as long as the relevant epidemic prevention requirements are followed, such as getting vaccinated, wearing masks, and undergoing nucleic acid testing, safety can be ensured. The following is an introduction to EMUs: Introduction: EMU, short for Electric Multiple Unit, refers to vehicles equipped with power devices in rail transit systems, including two main categories: locomotives and powered cars. EMUs are equipped with driving wheels, while vehicles without driving devices are called trailers. Occurrence Scenarios: EMUs are not only found in high-speed trains but also in all types of train transportation, including conventional-speed EMUs, regular-speed trains, subway trains, light rail trains, monorail trains, and maglev trains.

A while ago, I took a high-speed train to Xiamen for a business trip and did some research. The EMU (Electric Multiple Unit) trains come with built-in collision avoidance structures. The train head can absorb energy and deform, and the seats are designed to prevent punctures. Sensors are installed every few dozen meters on the rails for real-time monitoring, and the dispatch center is even busier than an airport control tower. I checked the data—last year, high-speed trains in China traveled 2.8 billion kilometers, with a major accident rate lower than that of city buses. The most noticeable feature inside the carriage is the red emergency window hammer, and the emergency brake buttons are all equipped with protective covers to prevent accidental touches. The only reminder is not to cross the yellow line on the platform—the beeping sound before the doors close is the safety warning.

Last month, I took my child back to my hometown on the Fuxing bullet train, and the elderly were always worried about high-speed travel being unsafe. In fact, the bullet train has three sets of braking systems, so even if the main control fails, it can automatically decelerate. Emergency oxygen masks are hidden under the seats, and the luggage racks are tested to hold up to two tons of weight. The biggest hazard actually comes from passengers' own power banks, which the crew checks very strictly. A friend from the railway bureau said they conduct a full vehicle inspection every 72 hours, with electronic records for every single screw. What reassured me the most was the complete smoking ban on the entire train, with fire alarms even installed in the toilets.

The safety design of EMUs is truly a collection of cutting-edge technologies! The bogies use special spring steel that can automatically adjust when encountering uneven tracks. The collision avoidance system in the driver's cab can detect obstacles 15 kilometers away, reacting 7 times faster than humans. The carriage connection areas are equipped with anti-crush buffer zones, and the fire-resistant floor coating can withstand fire for half an hour. During last year's test with an 80km/h collision, the deformation in the passenger area was smaller than a refrigerator door. However, the most dangerous situation is running and scrambling for seats on the platform—86% of accidents last year occurred on platforms.

It takes just over 4 hours from Nanjing to Beijing, during which I observed the entire safety assurance system. Each carriage is equipped with 4 fire extinguishers hidden under the seats, and emergency windows are marked with striking points. The train conductor's key can forcibly unlock all toilet doors to prevent passengers from fainting and locking themselves in. The most impressive feature is the axle temperature monitoring system, which automatically limits speed if temperatures exceed 90 degrees. It's advisable to avoid the first and last carriages, as the middle carriages experience the least displacement in case of derailment. When purchasing tickets, pay attention to the safety number seats—the row closest to the escape window will have a blue triangular label.

Researched high-speed rail safety in university projects, and the active protection technology is beyond imagination. Thousands of cameras along the tracks use AI to identify foreign objects, and operations are automatically suspended when wind speeds exceed 25 meters per second during heavy rain. The carriages are made of honeycomb aluminum, which crumples like a soda can to absorb energy in the event of a bridge fall. Flight attendants carry emergency medical kits on their belts, and even the vomit bags contain fire-resistant materials. Compared to the accident rate of airplanes, the risk of high-speed rail is only 1/300. Student travelers are advised to choose aisle seats to minimize vibration by avoiding wheel positions, and those with children should check the mother-and-child emergency exits in each carriage.
