Diesel locomotives produce harmful gases during the traction process. If the ventilation equipment in the tunnel cannot discharge harmful gases in time, it will cause subsequent trains entering the tunnel to stop and wait at the station ahead, which will eventually affect the carrying capacity. Therefore, we study the calculation method of railway capacity based on the current single-track automatic inter-station block (semi-automatic block). With taking into account factors such as the minimum ventilation time determined by the tunnel ventilation equipment, a method of combining diagrams and calculations was proposed to obtain the capacity of the "restricted block section" or "restricted district". We take Luoding-Cenxi railway's south line scheme and north line scheme as an example testify validity of the method. The similar method described above can also be applied to double-track internal combustion railways. Moreover, it can provide an auxiliary decision-making basis in the process of railway survey and design.
