How Do 2,500 Tons of Steel Stop? Train Braking Explained

Trains carry enormous mass and momentum, which makes stopping them a complex engineering challenge. From high-speed passenger trains to heavy freight wagons, different braking systems work together to control movement and ensure safety.

In this video, we take a clear and practical look at how train braking works, including:
Air (pneumatic) braking systems
Regenerative braking and energy recovery
Magnetic track brakes and emergency braking
Retarders and braking in hump yards
Mechanical parking brakes

By understanding the physics, engineering principles, and real-world operation behind these systems, it becomes clear why trains cannot stop like cars and why braking must be carefully distributed along the entire train.

This video is intended as an general and simplified overview for anyone interested in railway engineering, train operations or transport safety.
