Currently, it is necessary to support railway transport as a key element of passenger and freight transport. Railway transport must be the backbone of transport services, which must be implemented in the context of the basic goal of EU transport policy, which is to ensure the efficient use of the railway infrastructure, and thus the quality of passenger and freight transport. Therefore, it is necessary to ensure the high-quality use of the railway infrastructure, its adequate development and the constant process of modernization. The management and operation of the infrastructure is carried out by the infrastructure manager, which is usually owned by the state. The railway infrastructure is influenced by several important factors, which ultimately affect the quality and stability of the train traffic diagram. The main goal of the contribution is to briefly describe the current procedures and methodologies for the capacity of the railway infrastructure determining and using, but especially the proposal of new procedures and options for determining the scope and potential of the railway infrastructure. These indicators are also important from the point of view of determining the theoretical and practical permeability of the track sections. Subsequently, specific parameters and a specific recommended range of transport service will be proposed for each range. Last but not least, a brief practical application will be developed on the selected railway lines in individual European countries. The main contribution of the article, as well as the entire research presented, will be a more effective determination of the capacity of the railway infrastructure and the planning of the traffic operations scope on it.
