VENTILATION RESEARCH PROGRAM AT CASCADE TUNNEL, GREAT NORTHERN RAILWAY

A TEST AND RESEARCH PROGRAM WAS CONDUCTED IN PARIL 1966 IN THE GREAT NORTHERN RAILWAY'S CASCADE TUNNEL TO ASCERTAIN THE EFFECTS OF DIESEL-POWERED TRAINS MOVING THROUGH THE TUNNEL FROM THE STANDPOINTS OF VENTILATION AND ENGINE HEAT DISSIPATION. THE TEST PROGRAM INCLUDED ESTABLISHING MEASUREMENT STATIONS IN THE TUNNEL AND ON A LOCOMOTIVE CONSIST, RECORDING THE PRESSURES, AIR VELOCITIES AND TEMPERATURES AT THESE STATIONS, ANALYZING THE RESULTS AND USING AN ANALYTICAL APPROACH PREVIOUSLY DEVELOPED TO PREDICT THE EFFECTS OF TRAIN MOVEMENTS THROUGH A TUNNEL. THE TEST PROGRAM WAS GENERALLY SUCCESSFUL AND YIELDED THE DESIRED RESULTS. A COMPARISON OF PREDICTED AND OBSERVED RESULTS CONFIRMED THE VALIDITY OF THE ANALYTICAL APPROACH USED. /AUTHOR/
