In this century, with the rapid development of Chinese high-speed railway, as a main force of railway construction in China, SIYUAN has undertaken the survey & design works for a large number of national high-speed railway projects. Especially during the “eleventh five year plan” period, the length of completed high-speed railways designed by SIYUAN is up to 3,500 km, accounting for two thirds of the total mileage of newly built high-speed railways open to traffic in China; and the length of high-speed railways under construction designed by SIYUAN amounts to 6,000 km, about 40% of the total mileage of high-speed railways under construction in China. SIYUAN tops China and even the world in regard to its performance and achievement on the survey & design of high-speed railways.
