Abstract Research purposes: Combined with the upgrading of the Guangtong-Dali Railway, this paper analyzes the engineering measures and main technical standards for the upgrading project，including the comparison and selection of the upgrading schemes，ruling gradients，speed-raising upgrading, speed target value and the number of main tracks to provide the reference to the upgrading of exiting railways.
Research conclusions:(1)In the upgrading projects of existing railway，the existing railway is often unable to meet the demands of transportation due to its low standards, small transportation capacity and slow running speed. ( 2 ) Based on the idea of"capacity expansion by upgrading the existing line→capacity expansion and upgrading by building the second line→capacity expansion and upgrading by building the new double-track line"，the systematic study was done on this project. Combined with the features of the topographical conditions，geological conditions and urban planning along the railway，an reconstruction plan suitable for the convenient transportation organization，coordination of the capacities between lines and stations and getting the good economic benefits and strong market competitive capacity was selected after making an economical and technical comparison.(3)This study results is also available for the other projects of upgrading of existing railway.
