Relationship among China Railway Logistics Group, China Railway Materials Group and China Railway United International Container Co., Ltd.

Hello, there is no relationship between them, because, for example, China Railway Logistics Group registered the word China Railway Logistics, and there is no infringement. As long as there is a word difference in the registered name, it is not infringing, and so on. China Railway means China Railway Engineering Corporation, with only two words: China Railway, a state-owned enterprise, is a central enterprise supervised by the State-owned Assets Supervision and Administration Commission of the State Council, which mainly includes survey and design, construction and installation, and real estate development.
