Input (English): Context: The CRH3 is a version of the Siemens Velaro high-speed train used in China on the Beijing-Tianjin Intercity Rail line Wuhan-Guangzhou Passenger Dedicated Line Zhengzhou-Xi'an Passenger Dedicated Line and the Shanghai–Nanjing High-Speed Railway. It is capable of service speed of 380 km/h (236 mph) as the very similar Velaro E used in Spain but 300 mm (11.8 in) wider to take advantage of a more generous structure gauge and thus be able to fit in more seats in a 2+3 layout.
