China rolled out high-speed train sevices nationwide in April 2007. The high-speed train serving Beijing-Tianjin route will run

As of August 2008, this high-speed service has started to serve the section between Beijing and Tianjin at full speed. This section is actually part of a long high-speed track linking Beijing and Shanghai. Beijing-Tianjin is the first part finished. When it is fully completed, it will be the longest high-speed track in the world, with 80% of it on bridges. The longest bridge is 164.8 km long, the longest in the world. There are two types of trains running China's high-speed track, one type being a train designed for 350km per hour and the other being a revised version of a 300km-per-hour train but enhanced to handle 350km per hour. Both are designed and produced in China.
