The first bullet "train designed and manufactured in China with a speed of 300 kilometers per hour roiled off the production line on Saturday morning. The train was the latest model in the country' s China Railway High-speed (CRH) Series. This marks that China has joined a leading world club after Japan, France and Germany to become the fourth country capable of turning out such high speed trains. Previously, China' s fastest self-developed trains ran at a service speed of up to 250 km per hour.

Those trains, which presented to public on April 18, served the Beijing-Harbin, Beijing-Shanghai and. Beijing-Guangzhou routes. The new streamlined train was made of aluminum alloy(铝合金). The train body was the lightest of its kind in the world; Such a design was for the sake of energy economization. The train' s power was 12.7 kilowatts, lower than other high-speed trains, which was normally about 15 kilowatts.

The new train, which features a bar in the dining car and double-faced LCD TV screens in the first-class cars, was equipped with shock absorbers between carriages. As the train is running at a high speed, the shock absorbers are used to reduce shocking force and rocking of the train body. A train with eight carriages could seat about 600 passengers. They were expected to run on the 115-km Beijing-Tianjin route starting from August before the Beijing Olympic Games. It would reduce the journey time from the current 80 minutes to around 30 minutes.
