Which factor can affect a train's stopping distance?

• A. Environmental conditions such as rain or fog
• B. Train weight
• C. The speed of the train prior to braking
• D. The type of cargo being carried

Answer: (B)

The stopping distance of a train is significantly influenced by its weight. Heavier trains require a longer distance to stop because the momentum they possess is greater than that of lighter trains. When brakes are applied, a heavier train will generate more force due to its mass and inertia, which means more energy needs to be dissipated to bring it to a complete stop. Understanding the implications of train weight is critical for locomotive engineers, as it directly relates to safe stopping distances. Each train must be operated with its weight in mind to ensure stopping distances are maintained within safe limits, especially when carrying different loads or traveling at varying speeds. While other factors, such as environmental conditions, speed prior to braking, and the type of cargo, also play roles in the overall stopping dynamics, the weight of the train remains a foundational element in calculating and predicting stopping distance.
