China CNR Corporation Limited, the country's second-largest train maker, has won Bangladesh’s orders for its traction inverters and network control systems for bullet train, which are considered to be the heart and brain of bullet trains as they contain the core technology.

It is the very first time that China exports the core technology of its bullet train, and it marks that China has mastered this core technology through a long-time absorption and innovation after it is imported from foreign countries.

This contract contains 20 sets of high-speed rail network control systems, 40 sets of traction inverters and 40 sets of auxiliary inverters.

The two systems play a key role in the operation of bullet trains. The traction system decides the weight-carrying ability and stability of the trains, and the network control system manages the operation of the trains.
