In international trade, from a cargo departure point to destination point, there may be two basic ways to use transportation means, by sea or railway as there are geographically several  availabilities of airways ,railway lines and sea voyage lines and meantime transportation costs are dynamically changed, it is possible to draw some area by use of Geographic-Economic Line, which gives business people an easy reference for their choosing transportation means for logistic solution to some kinds of cargos. This paper first introduces general situation of China-Europe and Middle East block train development. Second the paper focused on China-Iran block train case, collected various railway and sea way transportation route and rate information to support deep analysis.
