Which component is involved in maintenance to prevent wear on tracks and rails?

Explanation:
Track/rail lubrication is the maintenance action that directly reduces wear on tracks and rails. Friction between the moving wheels or rollers and the rails wears surfaces over time; applying lubricant forms a protective film that lowers friction, reduces heat, and minimizes metal-to-metal contact. This slows wear, lowers noise, and extends the life of both the track and the rollers. The other options don’t directly prevent wear on tracks and rails: battery maintenance deals with power, building code requirements are standards, and a self-diagnostic system monitors performance rather than physically reducing wear.
