Why do trains take longer to stop on the runway?

Trains take longer to stop on the runway due to their significant mass and momentum, which require a greater distance to decelerate safely. Unlike cars, trains cannot quickly change their speed because of their heavy weight and the friction between the wheels and tracks. Additionally, the braking systems on trains, while powerful, are designed to provide a controlled stop over a longer distance to ensure safety and stability. This results in a longer stopping distance compared to other vehicles.
