The fouling point of a track is indicated by which of the following?

The fouling point of a track is indicated by which of the following?

• A. Yellow stripe
• B. Sign displaying FP
• C. Fixed Derail
• D. All of the above

Answer: (D)

The fouling point is the boundary where a train on one track can foul the adjacent track. This limit is shown in several ways to keep crews aware of the safe boundary. A yellow stripe is painted to mark the boundary, a sign displaying FP identifies the exact location, and a fixed derail provides a physical safeguard at the point. Since each of these indicators serves to mark or protect the fouling point, all of them are used to indicate it.
