Shanghai-Nanjing Intercity High Speed Railway designed by SIYUAN is 301km long in total, open to traffic on July 1, 2010.

Shanghai-Nanjing Intercity Railway running from Shanghai, via kunshan, Suzhou, Wuxi, Changzhou, Danyang, Zhenjiang, to Nanjing, is the start end and important part of the “Z”-shaped Nanjing –Shanghai-Hangzhou-Ningbo axis line in the . In order to realize the smooth travelling dream among Yangtze River Delta cities, SIYUAN had mainly taken the following measures for the demonstration line of intercity high seep railway:

Satisfy the urban traveling need: Since proposal bidding in 2004, SIYUAN had defined the route alignment and functional orientation of Shanghai-Nanjing Intercity High Speed Railway, i.e. basically parallel to the existing Shanghai-Nanjing Railway, and joining Beijing-Shanghai High Speed Railway and existing Shanghai-Nanjing railway to perform their own duties (medium- and short-distance passenger transport, long-distance passenger transport, and freight transport respectively) after completion, becoming 3 parallel winding railway “dragons” along cities between Shanghai and Nanjing. Hence, those cities along the Yangtze River as Shanghai, Kunshan, Suzhou, Wuxi, Changzhou, Zhenjing, Nanjing, etc. would be more closely connected, speeding up the flows of logistics and people, and “one integrated city effect” would be realized.。

Guide the development of intercity high speed railways: During the design of Shanghai- Nanjing Intercity Railway, due to the adoption of world -class unballasted track technology, train control technology, passenger station construction technology, centralized traffic control technology, etc., it becomes a showcase line with first-level technologies, advanced functions, and rational structures, also a demonstration line leading the trend of intercity high speed railway development across the world.

Given most parts of the Shanghai-Nanjing Intercity High Speed Railway line are of deep multi-layered soft soil, SIYUAN adopted pile-board or pile-raft structure to meet the requirement on site. It’s the first time for pile raft (pile board) structure to be widely used along a main line, and this successful experience have been applied for similar projects in Yangtze River Delta and even across the country.

In terms of rail track design, it’s the first domestic intercity high speed railway to adopt CRTS type-I unballasted track plates along the whole line, also the first railway time to be laid with self-developed high-speed unballasted track switch/ turnout. During construction, GRP point was used for the first time on the CRTS type-I unballasted track plate for accurate adjustment control of track plate laying, which had dramatically improved the track laying speed and accuracy, and have saved precious time for construction of Shanghai-Nanjing Intercity High Speed Railway.

As for bridge design, streamline shape corresponding to high speed railway features is adopted for pier body is adopted, which makes the pier light and beautiful while ensuring its strength. At several overpasses (of railway overcrossing existing line), steel-concrete composite portal pier structure is applied to ensure the construction safety.

In regard to station building design, with the design concept of “one station one scenery” , the external appearances of the station buildings integrated with the cultures and histories of the cities, and the flow lines inside stations reflected the inter-city characteristics and closely connected with urban rail transit system of other cities along the line, demonstrating the concept of “people orientation”.

For the overhead catenary systems, the technical design suitable for various speeds and the multiple-type EMUs automatic passing section separation technology are adopted. And the Signal system is of CTCS3 centralized train control system, the currently most advanced system in China.……

Improve the quality of city life: There’re altogether 21 stations along Shanghai-Nanjing Intercity High Speed Railway, which are densely distributed with average distance between stations of about 15km. The major stations are combined with corresponding passenger stations of the existing line. The CHR bullet trains are running acc. to two types of operation schedules, one of through traffic between major stations, the other of regular stopping at each station. The railway route is designed to cross the city center as far as possible, to be closely connected with urban rail transit system, genuinely embodying the “mass transit” characteristics of intercity railway.
