Brush control, road crossings, yards, and line-of-road are components of vegetation control for which system?

• A. Highways
• B. Railroads
• C. Airports
• D. Pipelines

Answer: (B)

These terms point to vegetation management along rail corridors. Brush control is kept to prevent trees and shrubs from encroaching on the tracks, which can obstruct visibility for train crews, interfere with signaling, or cause track damage. Road crossings require clear sightlines and predictable approaches so drivers and train operators can react safely; vegetation near crossings can hide signals or signs and reduce stopping distance visibility. Yards are rail yard areas where trains are assembled and stored, and keeping vegetation under control there helps maintain safe access to switches and tracks. Line-of-road refers to the stretch of track and its immediate surroundings that must be kept clear to ensure signals, switches, and the track itself remain visible and unobstructed for safe operation. These components are characteristic of railroad vegetation control, whereas the other options relate to different infrastructure contexts.
