Features the grade from the southern end of the Macdiarmid Tunnel to the northern approaches of the Postagoni River Bridge and includes signage, old crossings and the remains of a hot box/dragging equipment detector. *The cement barrel with the eyebolts is likely an anchor for a warning tower associated with the hotbox detector.
