Abstract
The paper presents the results of studying the distribution of air temperature along the length of an extended railway tunnel depending on various configurations and locations of tunnel heating and ventilation units. It is shown that the most rational way is the uniform arrangement of heating and ventilation units along the length of the tunnel combined with the installation of air-thermal curtains. This allows ensuring a positive air temperature in all sections along the length of the tunnel.
