Based on train traction calculation theories, this research first simulates the transports of a typically formed freight train hauled by representative types of freight locomotives in China. Accordingly, the exact change of the traction energy cost intensity of the train in the effect of its inter-stop transport distance is analyzed in a quantificational way for different target speeds. It is found that the inter-stop transport distance of a freight train should be no shorter than 20.00 kilometers in order to decrease the traction energy cost per unit transport especially for a relatively high target speed. As a result, it is suggested that the railway freight transport work ought to try its best to utilize a heavy load train in view of its average inter-stop transport distance of the whole trip and its comparatively energy-saving target speeds. Furthermore, as for the transport operation of a railway network, the requirements to the time of each transport work of a train and so on should also be considered for its traction energy saving in an integrated manner.
