railway level-crossing

Overall, the major conclusions in this paper are listed as follows. The construction of Beijing-Shanghai high-speed railway will have different an affect on the level, scope and regions.

本文主要的研究结论是：京沪高铁的建设对沿线地区的影响程度和范围存在差异。

Prediction and Software of Wayside Noise Level of High Speed Railway

高速铁路沿线噪声的预测计算及软件开发

Survey and Determination of Acoustic Power Level of Railway Regular Sound Source

铁路常见固定性声源声功率级的测定

Traditional railway freight stations are lagging behind the standards of modern logistics, due to its obsolete equipment and simple operation mode. As they fail to meet the high level and diverse requirements of passenger service, they are constraining the development of railway cargo transport station.

传统的铁路货运站，无论是陈旧的设备，还是单一的经营模式，都离现代物流的标准有很大的差距，无法适应旅客服务高层次和多样化的需求，成为铁路货运发展的制约。
