港口铁路区间双线同时同向运行通过能力研究

A Study on Increasing the Carrying Capacity in Unidirection Simultaneously of the Complex Track Railway of Port

港口铁路运输具有运价低,速度快,安全性高的优势。以宁波北仑港口铁路为例,将单线铁路建设为复线铁路,实现铁路区间双线自动闭塞运行,以提高运输效率。由于港口货物近年资源性物资比重大,在运输过程中存在运输方向不平衡性问题,应采取铁路双线同时同向运行可进一步提高运输效率,且铁路信号设备可保证同时同向运输安全要求。经综合分析,港口铁路区间双线同时同向运输可提高海铁联运能力及经济效益。

Railway transportation is quite inexpensive, quick and safe. The article takes Ningbo Beilun Harbor as an example, suggests building complex track railway for the harbor and carrying out automatic blocking, so as to improve the transportation efficiency. Among the goods transferred through the port, resource materials account for the largest proportion. Therefore there is an unbalance in the two directions of the railway transportation. The railways complex track automatic block transportation in the same direction simultaneously can increase the carrying capacity, and the railway signal equipment may guarantee the transportation safety. All in all, railway automatic block transportation in the same direction simultaneously can boost the combined transportation ability and the economic efficiency.
