本文简要回顾了“十五”特别是实施铁路跨越式发展以来中国铁路工程科技发展取得的成就，分析了“十一五’期间铁路工程科技发展需求、月标、重点任务和关键技术，提出为实现《中长期铁路网规划》，铁路工程科技发展需要围绕客运专线，既有线提速、重载铁路等重点和难点系统开展科技攻关及科研试验、实施科技发展目标必须增强自主创新能力、壮大创新团队、建设创新平台，加强知识产权保护。

In this paper, the brief review is offered of the development achievements of science and technology for railway construction in China in the "Tenth Five-year Plan" period, especially from the time of implementing strategy of railway leaping development, the analysis is made for the requirements, target, main tasks and key technologies required by development of science and technology for railway construction in "Eleventh Five-year Plan" period, and in order to realize "Mid-term and Long-term Railway Network Program", the thoughts are presented on development of science and technology for railway construction, that is it is necessary to tackle technical difficult problems and da scientific research tests focusing on passenger dedicated railway line, speed-raise of existing line and heavy-haul line. So the self-innovative ability should be strengthened, team for innovation should be enlarged, platform for innovation should be established and protection of property rights should be improved so as to realize the development target of science and technology.
