How long do trains take to stop?
Thereof, why do trains take so long to stop?
Why does it take so long for the train to stop after the brakes are applied? The optimal brake force results in a deceleration of about 2 mph per second. If you apply more brake force, the wheels will stop instead, and the train will glide along the rails resulting in a much longer stopping distance (and wheel damage).
Also asked, how long does it take for a train to stop going 50 mph?
Many freight trains average a mile in length. If the train is traveling 50 to 60 MPH, it takes about a minute to clear a crossing. At 30 MPH, it takes about two minutes to clear a crossing.
Conventional freight trains in the US can average nearly 2,000 metres (6,600 ft). Freight trains with a total length of three or four times that average are possible with the advent of distributed power, or additional locomotive units between or behind long chains of freight cars (referred to as a "consist").
