2 Answers
CRH380A and CRH380B differ in their basic braking systems, belonging to different series with distinct configurations. Different Series: CRH380A originates from the CRH2 series, with its prototype being the Japanese Kawasaki, while CRH380B comes from the CRH3 series, with its prototype being the German ICE. Different Configurations: CRH380A Motor Car: Wheel disc + tread cleaning, 4 sets/bogie. Wheel disc: 2 sets/axle. Tread cleaning: 2 sets/axle. Trailer Car: Wheel disc + axle disc + tread cleaning, 8 sets/bogie. Wheel disc: 2 sets/axle. Axle disc: 2 sets/axle. Tread cleaning: 2 sets/axle. CRH380B Motor Car: Wheel disc, 4 sets/bogie. Wheel disc: 2 sets/axle. Trailer Car: Axle disc, 6 sets/bogie. Axle disc: 3 sets/axle.
As a seasoned auto mechanic with years of experience, I see trains just like machines. The key differences between CRH380A and CRH380B lie in their core technologies. The 380A resembles a domestically developed Japanese-style design, featuring asynchronous motors that deliver fierce acceleration but with slightly more noise. The 380B, on the other hand, incorporates Siemens Velaro technology from Germany, utilizing permanent magnet synchronous motors for smoother starts and significantly better stability. Their cabin layouts also differ—the 380B offers more spacious seating and superior sound insulation, making long-distance journeys much more comfortable. In terms of air conditioning, the 380B cools faster and includes smart adjustment features, matching the efficiency of automotive automatic climate control. Both are rated for a top speed of 380 km/h, but in practice, the 380B proves more reliable and easier to maintain. From a user perspective, choosing between them is like selecting an engine for your car: the 380A suits those prioritizing raw power, while the 380B excels in safety and comfort. For regular maintenance, I recommend checking the electrical systems to prevent minor issues from compromising operational safety—after all, just like cars, the details define the experience in high-speed rail.
