Outcome-based education is a core idea of professional certification in engineering education, and a growing trend of current international higher engineering education. Taking the opportunity of the revision of specialty cultivation program for railway engineering, and taking the idea of outcome-based education as the mainline, specialty cultivation goal is set, 31 indices for graduation requirements are divided considering the cultivation goal, curriculum system covering all the indices is built, and course teaching outline is improved. Meanwhile detailed regulations are established to quantify graduation requirements for railway engineering. The revision is geared to professional certification in international engineering education, and lays the foundation for improving the quality of railway engineering undergraduates' cultivation.
