According to the report of South China Daily, with the upgrading of Guiguang Railway to a dedicated passenger line, the freight exchange between most parts of northwest China and Sichuan, Chongqing, Guizhou and the Pearl River Delta will be undertaken by Liu Zhao Railway, which has new requirements for railway capacity and design standards. Does this mean that the pre-feasibility study scheme designed by China Railway Consulting Company is different from that designed by China Railway Second Hospital? In this regard, the person in charge of Liuzhou Railway Waterway Construction Office expressed his approval.
It is understood that in order to promote the planning and project construction of Liu Zhao Railway as soon as possible, Liuzhou City began to entrust China Railway Second Hospital to carry out the research on Liu Zhao Railway Scheme in February last year. At the same time, after struggle, the project can be re-incorporated into the national medium-and long-term railway network planning according to procedures. The planned Liu Zhao railway project will be organized by the Ministry of Railways, and China Railway Engineering Design Consulting Group Co., Ltd. will win the bid to undertake the tasks of pre-feasibility study report and exploration design scheme preparation.
The Liu Zhao Railway Pre-feasibility Study Report compiled by China Railway Consulting Co., Ltd. started from Jinde Station of Liuzhou Hub, and suggested that it should cross Dayao Mountain by a long tunnel in the shortest air distance near Baizhang Township of Xiangzhou County, and then enter Guangdong eastward through Guiping, Pingnan County and Wuzhou City, with the end point in Zhaoqing City. The total length of the railway line is 4 10 km, which is a first-class double-track electrified railway of China Railway, with a speed target of 200 km/h.. "It is possible for Liu Zhao Railway to build another double line parallel to nanning-guangzhou railway, but it will not share the track with nanning-guangzhou railway." The person in charge said that due to the passenger transport function of the former Guiguang Railway, the connection scheme of Pingnan-Nanguang Line designed by the former China Railway Second Hospital could not adapt to the development of the new situation. Therefore, Liu Zhao Railway does not rule out the possibility of building along the north bank of Xijiang River after entering Guangdong, and passing through Fengkai and Deqing counties to Zhaoqing.
According to reports, it was agreed by the Railway Engineering Construction Office of the Autonomous Region and China Railway Consulting Co., Ltd. that the pre-feasibility study report of Liu Zhao Railway will be submitted before 25th of this month, and then submitted to the Ministry of Railways and the National Development and Reform Commission for approval.
