THEORETICAL CONSIDERATION ON TRAIN DRAUGHT IN LONG RAILWAY TUNNELS AND ITS APPLICATION TO PRACTICAL CASES

Ventilation of long double-track railway tunnels was investigated. Air flow involved with passing trains is basic to ventilation. A method for predicting exhaust gas concentrations when there are frequent diesel-powered trains was developed. A method for calculating temperature rise in tunnels traversed by frequent high-speed trains is described. The problem of temperature for the long Seikan tunnel has resulted in a recommendation for a longitudinal ventilation system.
