Construction significance

This line directly attracts Nanjing, the capital of Jiangsu Province, and Wanjiang, Anhui Province, with dense population, active economy, precious land resources and strong passenger demand. Nanjing-Anqing is a busy traffic passage between Anhui, Jiangsu and Shanghai, which is mainly composed of Ningwu Copper-Iron Railway, Tongling-Jiujiang Railway, National Highway G205, G3 18, Ningma Expressway and Yangtze River Shipping. In 2007, the whole society completed 33,565,438+million tons of freight, including 6.23% by railway, 63.36% by highway and 30.26% by water. The regional transportation structure is unreasonable. The existing Ningwu Railway is a single-track railway with low technical standards, small transport capacity and low bus travel speed. The utilization rate of parallel operation capacity reaches 97%, which can not meet the transportation needs. With the continuous growth of regional economy, the process of economic and social integration is accelerating, the links between cities along the line are getting closer and closer, and the passenger and freight volume will also increase. In 2020 and 2030, the maximum cross-section passenger density of the railway corridor is 6.5438+0760 million person/year and 26.43 million person/year respectively, and the freight density is 27.5 million tons/year and 35.8 million tons/year respectively. Therefore, it is urgent to expand it.
