Which statement correctly matches the track components to their primary functions?

Which statement correctly matches the track components to their primary functions?

• A. Sleepers distribute weight & maintain gauge; Rails guide wheels; Ballast drainage and support
• B. Sleepers guide wheels; Rails distribute weight; Ballast support
• C. Sleepers drain water; Rails support; Ballast guide wheels
• D. Sleepers store data; Rails light; Ballast weigh

Answer: (A)

The track components have distinct roles: sleepers (ties) distribute the train’s load and keep the track gauge set; rails provide the running surface and guide the wheels along the track; ballast provides drainage and a stable base that supports and holds everything in place. The statement matches these roles exactly, showing sleepers distributing weight and maintaining gauge, rails guiding wheels, and ballast handling drainage and support. The other descriptions mix up these functions (for example, a sleeper guiding wheels or ballast guiding wheels), which doesn’t fit how track components operate.
