-
A.
Sleeper
-
B.
Rail
-
C.
Ballast
-
D.
Tail lamp
Correct Answer:
D. Tail lamp
Explanation:
A tail lamp is a piece of portable equipment attached to the rear of the last vehicle in a train to indicate the end of the convoy. Unlike sleepers, rails, and ballast, which are fixed structural elements that form the physical permanent way, the tail lamp is not a part of the track infrastructure itself. Therefore, while it is essential for railway operations and safety, it is classified as a train signal rather than a track component.
