Justification of location of LNG infrastructure for dual-fuel locomotives on the railway network in Kazakhstan

Abstract

The article performs the justification of the dislocation place of the main infrastructure facilities of production, stations of equipment and filling station of liquefied natural gas (LNG) on the network of diesel traction of the Republic of Kazakhstan to provide the park of dual-fuel locomotives by LNG. The structural levels of the railway network on diesel traction are considered, the regional gravity zones are determined and the method of identifying the location of the main infrastructure objects of LNG with consideration of the volumes of transported cargo flow, the length of haul maintenance service and zoning run are developed. In addition, during identification of the locations of LNG infrastructure facilities, the location of the natural gas pipeline network in the territory of the Republic of Kazakhstan is considered.
