The method currently used for the estimation of train resistance based on specific train resistance has some shortcomings. This method is applied by various railway infrastructure managers, e.g. in the Czech Republic. In this article, first, the Czech formulae for the calculation of train resistance of freight trains are introduced and compared with selected foreign methods. Operational experience from recent years shows that the train resistance formulae used are too conservative and do not correspond to the state-of-the-art railway technology. Therefore, a modified approach for the estimation of train resistance is proposed in this paper. The modification is based on an analysis of run-down tests conducted with ordinary container trains currently operating on the Central European railway network. The contributing factors in the proposed train resistance formula are discussed.
