The paper presents analytical calculation and numerical simulation of fire, smoke and toxic gases spreading in the case of railways passenger train fire in a tunnelin view ofthe design features of certain types of Russian railway passenger cars and locomotives, the stages of the fire growth and the influence of various conditions on people safety in the tunnel. For a passenger train fire simulation we have used computational fluid dynamics model of fire-driven fluid flow based on solving a large-eddy simulation form of the Navier–Stokes equations appropriate for low-speed, thermally-driven flow with an emphasis on smoke and heat transport from fires, realized in the FDS program. The simulation results of various fire scenarios are given. The calculation of fire heat powerwas performedwith consideration for the properties of the flammable materials and design features of train cars and locomotives. The assessment of the provisioned people's safety was carried out. The results were applied in the design of railway tunnels in JSCS&R Design and Survey Institute "Lenmetrogiprotrans".
