The prediction of train drag and tunnel draught velocities in long tunnels, using the 1-D, quasi-steady, incompressible flow theory (TM-AERO-033)

A quasi-steady, incompressible, theory has been developed by Fukuchi and extended by Peacock to predict train drag and air speeds for the relatively simple cases involving one or two trains in a plain tunnel and a train in a tunnel with an air-shaft. This theory is now generalised further to...
