Research purposes： Lots of high quality multimedia products have been produced for the purpose of applying multimedia technology vividly, visually and high efficiently in railway design. Research methods： From the point of views of the constitution and characteristics of multimedia technology, the analyses are made for the applicable research and development of multimedia technology based on the actual condition of the Third Railway Survey and Design Institute Group Corporation. Research conclusions：Application of multimedia technology can commonly share the basic multimedia data as much as possible, which can avoid producing some elements of multimedia products repeatedly, enhance the production efficiency of multimedia and ensure the safety video technology in multimedia can capacity of computer multimedia for and reliability of multimedia products and files. Application of high quality computer make computer multimedia produced with digital video to scientifically integrate the handling engineering drawings with the capacity of digital video for handling pictures so as to produce high quality video products for construction. Application of large volume video data storage technology can store video data for being used again to form a multimedia management system. The storage mode can be on line or off line according to the real requirements and equipment＇s condition.
