Research Conclusions: There are three development trends for photographic surveying and remote sensing being applied in Chinese railway construction. The first one is there will be three new breakthroughs in the aspects of space resolution， spectrum resolution and time resolution，through which the remote sensing network with low-resolution ， medium- resolution and high-resolution being relatively complemented each other will be formed in combination with high orbit， medium orbit and low orbit ， with the aid of large-sized ， medium-sized and small-sized satellites. The second one is photographic surveying and remote sensing along with“3G”technology will be applied widely in Chinese railway construction. The third one is the railway management information service system will be formed by adopting remote sensing technology along with virtual and realistic techniques. In this way ， the system can serve the public vividly and easily with computer.
