Section XI

Supply Lines or Communication Lines Crossing over Railroads

111.2    Height Adjacent to Crossing

The vertical difference of the conductor level between the crossing and adjacent poles, towers or structures shall, at all times, be less than that which would produce an uplift strain on the pin, insulator or tie, on the poles, towers or structures adjacent to the crossing span, unless due precaution is taken to prevent the conductor from becoming detached from the crossarm.
