Abstract In 2006, Ministry of Railways decided to i m plement the technical recreation project of ballastless track for passenger dedicated line and the Wuhan comprehensive experimental section of Wuhan-Guangzhou High-speed Railway was built for recreation of complete set of ballastless track technology . Therefore , the researches were done on the theoretical design, structure design, fabrication process , track components , construction materials, construction equipments , track laying out technology and turnout for ballastless track to enrich and improve the ballastless track technology. This paper systematically describes the recreation and practice of ballastless track technology, gives an introduction to the main research contents, main recreative achievements and train tests, puts forward the the advices and suggestions on the quality control of the ballastless track engineering, and expresses the ideas on the continuous recreation of ballstless track technology.
