Section 705.080 - Open-top cars: Excessive height or widthNo movement of open-top cars containing lading extending in excess of 15 feet 6 inches in height above the top of the rail or extending laterally in excess of 5 feet 5 inches from the center line of the car, may be made except under the following conditions:
1. The operation of cars, the lading on which extends laterally in excess of 5 feet 5 inches from the center line of the car, is restricted to lading the size or dimensions of which cannot be reduced.2. All open-top cars with lading extending laterally in excess of 5 feet 5 inches from the center line of the car or in excess of 15 feet 6 inches in height above the top of the rail must be placarded on the load in a conspicuous place, and each such car must be marked, stenciled or placarded at locations described in subsection 3 of NAC 705.090.3. All open-top cars with lading extending laterally in excess of 5 feet 5 inches from the center line of the car, if the length of the train permits, must be at least five cars from the caboose.4. All members of the crew of each train containing cars, the lading on which extends laterally in excess of 5 feet 5 1/2 inches from the center line of the car or in excess of 15 feet 6 inches in height above the top of the rail, must be informed by an appropriate train order or message that the train includes such cars. The information must also include the total number of such cars and notice that no member of the train crew is required to ride on any such cars.5. All members of the crews of trains whose operations may be affected by the presence or operation of other trains having loads as wide as those described in subsection 4 must be informed by an appropriate order or message advising them of that condition.6. Yard supervisors must be notified sufficiently in advance of the arrival of cars on which the lading extends laterally in excess of 5 feet 5 1/2 inches from the center line of the car to enable supervisors to take the necessary precautions to safeguard employees in the yard.7. Cars on which the lading exceeds 15 feet 6 inches in height above the top of the rail, if otherwise in compliance with requirements of this chapter as to width of lading, and the nature of which precludes the probability of employees getting on top of or passing over them, are exempt from the conditions of this section. If the train length permits, any such cars, except cars transporting highway trucks or trailers, without open-lading, multilevel freight cars either loaded or unloaded and automobile underframe cars, must be at least five cars from both the caboose and the engine, and a buffer car (any car not carrying a trailer or semitrailer with open-lading cargo) must be placed immediately ahead of the caboose or immediately behind the locomotive. For the purposes of this section, automobile underframe cars are either special flat cars upon which automobile underframes are stacked and firmly secured in a horizontal position or gondola cars in which such underframes are placed on end and firmly secured to the gondola cars.Nev.
