How long does it take for a train to stop?

How long would it take for train going 80km/h (50mph) to stop?

  • No actual calculations needs to be shown; estimations will do just fine. If there was a 132 tonnes freight train traveling at 80km/h (50mph), how long would it take to stop. If it ...show more

  • Answer:

    1/4 to 1/3 of a mile. This is if the engineer applys the emergency brake system. This brakes the locomotive and rail cars at the fastest rate without locking the wheels.

it all depends on the maximum friction on the breaking system before the wheels begin to skid the fricition between wheels and rails and the friction between brake pad and rotor strangely the bottom of the wheel in contact with the rail is going BACKWARD ast exactly the same speed as the train is going forward and the friction is STATIC or standing still which is usually greater than then sliding fricition on the brake pad to rotor all the motion energy of the mass of the train has to be converted into heat it can be a complicated but solvable engineering problem

Richard B

about 1/3 of a mile if tones is tons.

UPRRocks

About 1.5/2miles

Average stopping distance for a train of that size, at that speed, is 2 miles.
