An Assumption of Standardization of Track Facilities for Urban Rail Transit

Research purposes: The increasing busyness of urban traffic can be fundamentally solved by the urban rail transit.This is accepted by all circles.Because of the difference between the criterion of different railway systems and the disunity among different railway facility types,much inconvenience is brought to design,construction and maintenance.Therefore,we are exigent to solve the standardization problem of equipments for urban rail transit.Research methods:This paper investigates the existing domestic urban rail transit,the condition of the rail fastener and turnout,analyzes the sticking point and harm,studies the solution methods and measurements.Research results:The standardization of the track facilities of urban rail transit is imperative.According to the present situation,it could be divided into three steps: simplification,standardization and serialization.Aimed at the trend that special turnout is asked for to meet the demand of urban rail transit,some schemes for standardization must be brought forward as early as possible.Research conclusions:The first step is to control the quantity of railway facility types to the present condition,and new product will not be developed no longer.Some products that the ratio between performance and price is more reasonable will be chosen,its design will be optimized,then they will be made as the standard figures or universal figures.In addition to meet the requirements of different project condition,there must be some series products for different specification.The standardization must be attached importance to and intervened by the upper leaders,nail down the interrelated department and the power to examine and approve the standard figures;perfect the process of examination and approval,then the standardization would be realized well-off.
