Abstract The completion of Tokai new main lines with the speed of 200 km/h in Japan in 1964 uncovered the prelude of the express railway development. Owing to more & economical character, express railway meets the need of economical and social development in variable Country. So every country competes in enhancing speed and constructing express passenger railway. Until now, there are ten countries which have constructed express railway above 200 km/h. The construction and development of express railway Indicate that world railway has entered the highspeed developmental times. This paper is not concerned about the comparison among the express system modes. The issues relate to express railway with the program of high speed and moderate speed in common-line, which is reported to state to ratified, will be argued. This paper will discuss the definition on the objective value of express railway speed. It will make a conclusion that it is urgent to develop express railway and will provide optimization method to selection parameters in the program of high speed and moderate speed in common-line. The conclusion in this paper will be references in the railway planning and construction and the basis for further research.
