How China adapted German engineering to build the world's largest high-speed rail fleet

Society · Published 9 October 2026 Swipe more like this →

In short: The CRH3 Hexie, or Harmony, transformed Chinese rail by taking the German Siemens Velaro platform and widening it to fit more passengers. This adaptation sparked a massive production scale, eventually leading to record-breaking speeds and a complex evolution of train variants that now define China's high-speed transit network.

The CRH3 story began in November 2005 when the Chinese Ministry of Railways ordered 60 Velaro trains from Siemens. While based on the German ICE 3, the Chinese version was engineered to be 300 mm wider, allowing for a 2+3 seating configuration that maximizes capacity. A standard 200-meter CRH3 trainset accommodates 572 passengers, with 16 seats in deluxe class, 56 in first class, and 528 in second class. The initial units were built in Germany, but production quickly shifted to domestic facilities like Tangshan Railway Vehicle, marking a significant transition in manufacturing technology.

The platform proved exceptionally versatile, spawning numerous variants including the CRH380 series. These trains were designed for high-speed performance, with the CRH380BL reaching a staggering 487.3 km/h during a test in January 2011. This rapid expansion was unprecedented; a single 2009 contract for 100 16-car trainsets involved 1,600 railway cars, a production volume exceeding the total number of Velaro and ICE trains manufactured globally up to that point. By August 2017, hundreds of these units were in active service across China's passenger-dedicated lines.

Despite these achievements, the fleet faced operational hurdles. In August 2011, all 54 CRH380BL trainsets were recalled following reports that the electronics were too sensitive to stormy weather. The trains were later returned to service after adjustments. The platform continues to evolve, with newer iterations like the CRH3A designed for lower-speed intercity routes and ongoing development of modular trainsets that allow for swapping cars based on demand. Today, the CRH3 remains a cornerstone of Chinese infrastructure, representing a massive scale of industrial output and a continuous cycle of technical refinement.
