Which maintenance practice directly affects braking performance?

Regular brake inspections and adjustments are crucial maintenance practices that have a direct impact on braking performance. This process ensures that the brake components are functioning correctly, are free from wear and tear, and are properly calibrated for effective stopping power. Regularly checking the brake pads, rotors, shoes, and hydraulic systems helps identify any issues before they lead to malfunction while the train is in operation.

Additionally, adjustments to braking systems can optimize the response of brakes, ensuring that the train can stop safely and efficiently under various conditions. This can involve adjusting the tension on brake cables, ensuring that brake shoes make proper contact with wheels, and verifying that the hydraulic systems are properly maintained. All of these actions collectively enhance the reliability and effectiveness of the braking system, which is critical for safe train operation.

The other options, while relevant to overall train operation and safety, do not have the same direct consequence on braking performance. Track alignment checks focus on the tracks themselves rather than the train’s braking capabilities. General train cleanliness is important for aesthetics and hygiene, but it doesn’t directly influence how well brakes perform. Monitoring passenger satisfaction can provide valuable feedback for service improvement but does not affect the mechanical function of the brakes.
