Abstract Research purposes: Through reference to the operation practice of similar railway and based on the engineering and geological characteristics of Ningbo—Taizhou—Wenzhou Railway．all influence factors oil speed—raise of the railway are analyzed，the measures to be taken and the problems to be studied are offered and the feasibility of further speed—raise of the railway is verified．
Research conclusions: Through analyzing the construction standards and technical measures for various infrastructures and auxiliary projects，to further raise the railway speed is feasible．By adjusting partial ballast thickness，improving the grades of ballast and reinforcing the subgrade，the goal of running 250 km／h train can be achieved．On the whole， transportation organization and various engineering technology can adapt to the requirement of running 300 km／h train in future，but transportation pattern and signaling system should be further studied and perfected．
