Kinetic friction is the force that stops a train when the brakes are applied
A train's brakes start exerting force on the wheels when the brake system is activated by the engineer using either compressed air (pneumatic brakes) or electricity (electric brakes). The force applied by the brakes creates friction between the brake pads and the wheels, which slows down the train.
Heat, from the friction in the brakes.
Transrapid Maglevs slow down and stop using a combination of electromagnetic brakes and eddy-current brakes. Electromagnetic brakes work by applying a magnetic field to the track, which induces a current in the moving magnets of the train, creating a force that opposes the motion. Eddy-current brakes work by creating a magnetic field that interacts with the conducting track, generating eddy currents which create an opposite magnetic field that slows down the train. These braking systems work together to gradually slow down and bring the Transrapid Maglev to a stop.
No, stepping on the brakes of a moving train is an example of deceleration, as it is the action of slowing down or reducing the speed of the train. Acceleration refers to an increase in speed or velocity.
The amount of thermal energy generated by the brakes of a train in slowing down from one speed to another depends on the mass of the train, the initial and final speeds, and the efficiency of the braking system. The energy is converted from the kinetic energy of the train into heat energy by the brakes. The specific calculation would require more details about the system.

It can take a train traveling at 55 mph anywhere between 1 to 2 miles to come to a complete stop after the emergency brakes are applied, depending on various factors like the weight of the train and track conditions.
Trains do not stop immediately after applying brakes due to their large mass and momentum. It takes time for the brakes to slow down the moving train, and the distance needed to stop depends on the train's speed, weight, and the effectiveness of the braking system. Additionally, train brakes are designed to prevent skidding and provide a smooth and controlled stop.

A train has brakes similar to a car at every wheel (friction brakes), and also can use its locomotive power to apply a braking force (called dynamic braking). If any train wheels lock-up (stop moving) the sliding wheels do not slow the train as quickly as they are designed to do. In the US, modern locomotives use computerized braking systems, as do passenger trains. Freight cars are limited to the friction brakes and often this is where you may see a set of train wheels lock-up when they shouldn't.
When a moving train stops, its kinetic energy is primarily converted into heat energy due to friction between the train's brakes and the track. Additionally, some kinetic energy may also be converted into sound energy and vibration energy during the process of stopping.
