Constantly increasing of the people mobility requires ensuring of the sustainable transport operation. One of the priorities in this area is a reduction of the energy consumption and the GHG production by transport. Emission limits are currently applied mainly to the transport vehicles. However, technical characteristics of the transport infrastructure may also affect the energy consumption and the GHG production of the transport operation. The article analyses the impact of the changes in the railway infrastructure parameters on the change in the energy consumption of the train operation and on the GHG production in railway passenger transport. The analysis is based on the simulation in the Dynamics program at the different slope ratios of the railway track. The calculation is made for the diesel traction of the vehicles. The aim of the article is to highlight how designing of the new or reconstructing of the older track lines could affect the energy consumption and GHG production of the future railway transport system.
