Abstract：Research purposes ： Urban mass transit system has its depot and multi - purpose base. This paper researches the relative track structures for different types of yard tracks on the basis of investigation of applicable situations of yard tracks for some depots and integrated bases of urban mass transit in China and presents the optimum design of yard track structure on the basis of national railway theory and experience.
Research conclusions ： Ballast bed should be installed for the test track and track outside the depot, which can reduce the vibration and the engineering cost, and the stanchion or adit monolithic track bed should be installed for the track inside the depot according to the different technological requirements so as to maintain easily and reduce maintenance works significantly. Use of flexible fastenings on the track can improve the track safety and stability without any reinforcement and reduce maintenance works. The track can work better by installing the auxiliary equipments，such as crossing and buffer stop.
