New-energy technologies have been widely researched,spread and applied in railway,the achievement of"Green Railway"goal is promoted effectively.The standard system of railway new-energy technology plays an impor-tant role in promoting and guiding the development and application of new-energy technology in railways,however the research gap of the standard system of railway new-energy technology is still exist at present.In this paper,a prin-ciples for building standard system are proposed,characteristics of new-energy technology utilized in railway are ana-lyzed,national standards,industry standards and local standards related to new-energy are arranged and identified,the standard system of railway new-energy technology is built according to the way of energy classification,advices of formulation and revision of railway new-energy technology standard are given,which can provide reference and guid-ance for optimization and improvement of new-energy technology standard system of our country.
