Abstract：Research purposes: This paper discusses and resolves existing key weak parts in the railway construction and development in Chengde region，proposes the rational railway network layout.
Research methods: This paper indentifies existing week parts in regional railway network and proposes rational layout frame by systemic analysis on the layout , standard and capacity according to the natural and economic profile and existing railway network status in Chengde Region.
Research results: There are some weak parts in currently existed railway network of Chengde region，including irrational layout low technical standard and low transport capacity. These weaknesses should be strengthened and additional works should be done to improve the situation.
Research Conclusions: The following measures should be taken to improve the railway network layout in Chengde region: (1)Building energy resources transport corridor and entering ocean corridor.(2)Building entering Beijing high capacity fast corridor.(3)Improving existed railway technical standard level as high as possible at minimum cost. And building a railway network with proper scale，rational layout , sufficient capacity , a key frame of”one longitudinal two transversal"，in radical form from city centre to regional counties.
