When may rolling equipment enter a track where a blue signal is displayed at the entrance to the track?

Explanation:
Blue signals at the entrance to a track are safety protection for workers on or near the track. When this signal is displayed, rolling equipment is not permitted to enter that track under any circumstance. The track remains restricted until the protection is removed and normal entry conditions are restored. Written authorization or a clearance from RTC do not override this protection, so entry can only occur after the blue signal is no longer in effect and the track is explicitly ready for movement.
