What process is likely being inspected in the stations?

The process being inspected in the stations is likely the cleaning of equipment because maintaining cleanliness is crucial for safe and efficient train operations. Regular cleaning ensures that all equipment, including tracks, train interiors, and signaling systems, remain in optimal working condition. This process not only prevents malfunctions due to dirt and debris but also enhances the overall passenger experience by keeping the environment hygienic.

While the installation of new machinery, the effectiveness of safety protocols, and the functionality of air systems are also essential aspects of train operations, they are typically subject to specific inspections at different times. Cleaning, however, is a routine operation that occurs frequently and is vital for immediate operational integrity and safety. Regular inspections of cleaning practices help ensure compliance with hygiene standards, especially in light of health and safety regulations.
