The invention discloses an emergent rescue station for a railway tunnel. The emergent rescue station is arranged inside the railway tunnel. The emergent rescue station is characterized in that the two ends of the emergent rescue station are each connected with a large-diameter one-tunnel double-line shield tunnel, the emergent rescue station and the shield tunnels are each of an identical upper-layer and lower-layer structure, wherein a reinforced concrete structure is formed between the upper layer and the lower layer, the upper layer of the emergent rescue station is a rail mounted space communicated with the tunnels so that trains can travel, the lower layer of the emergent rescue station is an emergent rescue layer communicated with a tunnel escape channel, the upper layer and the lower layer are connected through a chair, the lower evacuation layer and the upper rail mounted layer are isolated, safety space can be provided for personnel evacuated from the trains, and the personnel can be rescued out the tunnels through the bottom communicated escape channel. The emergent rescue station can effectively achieve the purpose of intermediate rescue of the large-diameter one-tunnel double-line shield tunnels and avoid unnecessary waste caused by adding or enlarging a silo or additionally arranging an auxiliary underground tunnel and the like.
