(1)
From March through November, the draw shall be left in the open position to vessels and will only be closed for the passage of trains and to perform periodic maintenance authorized in accordance with subpart A of this part.
(i)
Trains shall be controlled so that any delay in opening of the draw shall not exceed ten minutes except as provided in § 117.31(b).
(ii)
Before the bridge closes for any reason, an on-site train crewmember will observe the waterway for approaching craft, which will be allowed to pass. An on-site train crewmember will then operate the bridge by radiophone. The bridge shall only be closed if an on-site train crewmember's visual inspection shows that the channel is clear and there are no vessels transiting in the area.
(iii)
While the CONRAIL Railroad Bridge is moving from the full open to the full closed position, an on-site train crewmember will maintain constant surveillance of the navigational channel to ensure no conflict with maritime traffic exists. In the event of failure or obstruction, the on-site train crewmember will stop the bridge and return the bridge to the open position.
(iv)
During closing of the span, the channel traffic lights will flash red, the horn will sound five short blasts, and an audio voice warning device will announce bridge movement, and the bridge will close. When the bridge is seated and locked down to vessels, the channel traffic lights will continue to flash red. When the rail traffic has cleared the swing span, the horn will sound one prolonged blast followed by one short blast to signal the draw of the CONRAIL Railroad Bridge is about to return to its full open position to vessels.
(v)
During open span movement, the channel traffic lights will flash red, the horn will sound one prolonged blast followed by one short blast, then a pause, and an audio voice warning will announce bridge movement until the bridge is in the full open position. In the full open position, the channel traffic lights will flash green.
