Your numbers are fubar so I'll use my own, and show my work.
M = 80,000 Kg
Vi = 600 Km/h / 3600s *1000m = 166m/s
Vf = 0 m/s
T = 10s
A = (Vf - Vi) / T = (0m/s - 166m/s) / 10s = 16.67 m/s^2
F = M*A = 80,000 Kg * 16.67 m/s^2 = 1,333,600 N
Okay, a million Newtons. Great whats that in pounds?
(1,333,060N/9.8m/s^2) * 2.205 = 300,060 Lbs / 2,000 = 150 tons over 57,000 square inches is about 5 pounds, not 190 tons. Thats not going to go through SIX CONCRETE WALLS.
Well I didn't think 5 pounds per square inch was very badass so I gave it one second to stop and 14' x 14' to apply all the force. After that I got 105 pounds per square inch. Thats 7 tons per square foot that could do some severe damage for sure! Like rip the wings off upon initial contact with the E ring. like in this picture;
