The draw of the Norfolk Southern Railroad Bridge, mile 1.4 at Wilmington, shall operate as follows: (1) The draw shall remain in the open position for navigation. The draw shall only be closed for train crossings or periodic maintenance authorized in accordance with subpart A of this part. (2) The bridge shall be operated by the controller at the Harrisburg, PA Dispatcher's Office. The controller shall monitor vessel traffic with closed circuit cameras and infrared sensors covering the swing radius. Operational information will be provided 24 hours a day on marine channel 13 and via telephone (717) 541-2140. (3) The bridge shall not be operated from the remote location in the following events: Failure or obstruction of the infrared sensors, closed-circuit cameras or marine-radio communications, or anytime controller's visibility is inhibited. In these situations, a bridge tender with Norfolk Southern must be called and on-site within 30 minutes. (4) Before the bridge closes for any reason, the remote operator will monitor waterway traffic in the area. The bridge shall only be closed if the off-site remote operator's visual inspection shows that the channel is clear and there are no vessels transiting in the area. While the bridge is moving, the operator shall maintain constant surveillance of the navigation channel. (5) Before closing the draw, the channel traffic lights would change from flashing green to flashing red, the horn will sound five short blasts, and an audio voice warning stating, "œAttention, Attention. Norfolk Southern Railroad Bridge over Christina River at milepost 1.4 will be closing to river traffic."A Five short blasts of the horn will continue until the bridge is seated and locked down to vessels. The channel traffic lights will continue to flash red. (6) When the rail traffic has cleared, the horn will sound one prolonged blast followed by one short blast to indicate the draw is opening to vessel traffic. During the opening swing movement, the channel traffic lights would flash red until the bridge returns to the fully open position. In the full open position to vessels, the bridge channel lights will flash green followed by an announcement stating, "œSecurity, security, security. Norfolk Southern Railroad Bridge over Christina River at mile 1.4 is open for river traffic."A Vessels shall stay clear of both channels as to not interfere with infrared detectors, until green lights are displayed on the swing span.
