Final answer:
Trains need to prepare to stop up to 2000 meters in advance. This is because trains require a certain distance to safely come to a stop, especially when they are traveling at high speeds. The stopping distance for a train depends on factors such as its speed, weight, and braking system.
Step-by-step explanation:
Trains need to prepare to stop up to 2000 meters in advance. This is because trains require a certain distance to safely come to a stop, especially when they are traveling at high speeds. The stopping distance for a train depends on factors such as its speed, weight, and braking system.
For example, a heavy freight train traveling at a high speed will require a greater distance to stop compared to a lighter passenger train. Similarly, a train with a more advanced braking system will be able to stop in a shorter distance compared to a train with less advanced brakes.
Therefore, trains need to anticipate their stops well in advance to ensure the safety of passengers and prevent accidents.
