随着对外开放、对内搞活的深入发展，人民物质和文化生活水平的不断提高，客运量还将大幅度增长。修建京哈等高速客运专线，实行客货列车分线运行，是一种较常规方法技术层次更高，扩能幅度更大的手段．在修建高速客运专线之后，既有线的大部分旅客列车可转移到高速客运专线之后，腾出的能力即可用于完成货物运输任务。东北地区发展高速铁路是东北铁路发展的唯一方向．
With the opening-up to the outside world and the deepening development of invigorating the interior, the people’s material and cultural living standards will continue to improve, and the passenger traffic will also increase substantially. The construction of Jingha and other high-speed passenger dedicated lines, the implementation of passenger and freight train line operation, is a higher level than the conventional method of technology, more substantial means of expansion. After the construction of a high-speed passenger dedicated line, most of the existing passenger trains can be transferred to the high-speed passenger dedicated line and the free capacity can be used for the completion of the cargo transportation task. The development of northeast China’s high-speed railway is the only direction for the development of the Northeast Railway.
