China Railway CR400AF

The CR400AF Fuxing is a Chinese electric high-speed train developed by CRRC Changchun Railway Vehicles and manufactured by CRRC Qingdao Sifang. As part of the China Standardized EMU, the CR400AF is designed to operate at a cruise speed of 350 km/h and a maximum speed of 420 km/h in commercial service. Development on the project started in 2012, and the design plan was finished in September 2014. The first EMU rolled off the production line on 30 June 2015. The series received its current designation of Fuxing in June 2017, with the nickname Red Dragon. It is among the world's fastest conventional high-speed trains in regular service, with an operating speed of 350 km/h.

A derivative version of this train known as KCIC400AF or Komodo Merah (lit. 'red komodo dragon') or Petir Merah (lit. 'red lightning') is exported for operations in Indonesia on their Jakarta–Bandung high-speed railway.

Variants
All variants of the Fuxing train are compatible. The EMU models share the same standard required by China Railway Corporation, hence the name China Standardized EMU. Fuxing train models can be identified by the designation. No letter after the dash indicates the standard 8-car configuration. A indicates a 16-car configuration; B indicates 17-car configurations; C indicates 8-car multiple units with automatic train operation capability; G indicates 8-car sandstorm and cold climate resistant trainset; and Z indicates 8-car configuration with redesigned interior and exterior. Some variants have two letters indicating combined configuration, such as type GZ being the train set featuring extreme weather resistant capability (type G) and redesigned interior and exterior (type Z).
