Research on speed target value of railway engineering

The composition scheme of speed target value of railway engineering contains the functional orientation of railway line,demand of time target value and the adaptation to the adjacent lines. The selected speed target value of railway engineering must be suited to the features of the railway, satisfied with transport requirement, accorded to railway developing strategy and realized to the best economic benefit. This paper comprehensively compares and analyzes different speed target value schemes adopted by Revamping project for Capacity expansion of WANGAN railway and a reasonable speed target value-200km/h reserved 250 km/h is recommended.
