Research purposes： The descriptions are given in this paper for the main functions and classification method of railway sleepers as well as the development experience of railway sleeper and existing problems. Research methods： Based on the development experiences of railway sleeper and the sleeper for urban mass transit, the summary is made for sleeper classification method, the introduction is given to the main features of wood sleeper, concrete sleeper and the special sleeper for urban mass transit, and the investigation and research are made on the problems in design, manufacture, application and maintenance of all kinds of sleepers. Research results：The information is provided about the board concrete tie already used over four years in Qinhuangdao - Shenyang Passenger Dedicated Railway Line and the board concrete tie which is in the stage of design and tendering for intercity mass transit between Beijing and Tianjin. Research conclusions： The development of railway sleeper and sleeper for urban mass transit should be followed ： adding the types of concrete sleeper to satisfy the different laying conditions demands; improving the use life of concrete sleeper; developing and researching the new varieties of railway sleeper to adopt the fast development demands of China high- speed railway, heavy haul railway and urban rail transportation.
