VENTILATION RESEARCH PROGRAM AT CASCADE TUNNEL, GREAT NORTHERN RAILWAY

A test and research program was conducted in April 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 fielded the desired results. A comparison of predicted and observed results confirmed the validity of the analytical approach used.
