Abstract：Research purposes: The analysis and discussion are made of the two important issues of heavy haul railway, namely the transportation organization and the existing railway improvement, in order to summarize the common mode available for the current domestic conditions and provide effective and practicable plans.
Research methods: The common features are presented and several possible modes are offered for heavy haul transportation and track improvement based on the examples of Datong-Qinhuangdao Railway and Beitongpu Railway.
Research results: According to the heavy haul railway's transporting characteristics that the transported goods mainly is coal, all the links of loading, transportation, unloading, empty car backing and the management of locomotives shall be paid attention to in transportation organization. The rail, subgrade, bridge and culverts should be improved to track.
Research Conclusions: In accordance with different transport features of heavy haul railway the different transport modes are proposed, that is, haul load should be up to 5 000 tons, 10 000 tons and 20000 tons. The circulating transport method of unloading wagon tipper directly should be adopted to shorten the marshalling and decomposing time. The arrival and departure tracks in technical station and intermediate station should be long enough to meet requirements subgrade, bridges and culverts should be improved with higher standard.
