Abstract: In response to the high dependence of cloud platforms in the railway industry on foreign products, thispaper studied the construction plan of independently controllable cloud platforms in the railway industry, and designs and implements a domestically produced virtual cloud platform for railways. On this basis, the paper discussed the adaptation plan for the migration of railway information system applications to localization virtual cloud platform, elaborated on the principles and processes of application migration, and introduced specific migration methods such as middleware and databases. This scheme has been applied to China Railway Lanzhou Group Co. Ltd. and successfully migrated the network office system of the group company to the localization cloud platform, which provides reference for the subsequent localization substitution work of the railway industry.
