Where: ΔP is the difference of dynamic pressure in front and behind of the train; 𝑉𝑡𝑟 - speed of trains in the tunnel; 𝑊ℎ - the velocity of air flow in space between perimeters of train and tunnel; Str = 4.00; 5.00; 6.25 - Area of the cross section of the train, m2; 𝑉𝑓 - air speed originated by the piston effect on the front of the train; S0 = 16 - Tunnel cross section, m2.	cache/gs-277.pdf	txt/gs-277.txt
