What type of maintenance involves checking train components on a regular basis?

Preventive maintenance is focused on regularly scheduled inspections and maintenance activities to ensure that train components function properly and to prevent potential failures. The intent of this type of maintenance is to maintain equipment reliability and extend its lifespan by addressing wear and tear before issues become serious. This can include tasks such as routine checks, servicing, lubrication, and replacing parts as they approach the end of their expected life cycle.

In contrast, other forms of maintenance like corrective maintenance involve making repairs after a failure has occurred, which does not emphasize regular checks. Reactive maintenance is similar, as it is conducted in response to unplanned failures without any prior preventative measures being taken. Predictive maintenance relies on data and condition monitoring to anticipate when maintenance should occur based on the actual condition of equipment, rather than on a set schedule.

Thus, preventive maintenance is the best approach when it comes to consistently checking train components to avoid breakdowns and ensure safe operation.
