Abstract Research purposes:The Quzhou一Ningde Railway is the important traffic passage for the Ningde Harbor on the Strait west bank and the port一vicinity industry. This railway links many railways and crosses the southwest area of Zhejiang Province and the northeast area of Fujian Province with big rising and falling topography一It is difficulty to build this railway. The maximum ruling of this railway is crucial to the railway alignment，length，investment，operating expenditure，traction quality and transportation capacity. So it is necessary to determine the maximum ruling gradient of this railway through comparison of the optional schemes on consideration of the railway 's functional orientation，transportation requirements，technical standards of adjacent lines in the network and development tendency of traction power and ruling gradient system.

Research conclusions:The twin一locomotive traction on the whole railway line or in certain sections of the line can not give the superiority of the large ruling gradient，with high operating expenditure and inconvenient transportation organization. By adopting both maximum ruling gradients of 6‰and 9‰ the single locomotive can be used for the whole railway with smooth transportation organization.It is recommended to adopt the maximum ruling gradient of 9‰ because it suits the landform along the line，saves the construction investment and cost and obtains the maximum overall benefits.

Key words： Quzhou—Ningde Railway maximum ruling gradient research
