Telephone, telegraph or street railway companies, may acquire a right-of-way across railroads by condemnation by proceeding in accordance with the provisions of this chapter. If a right-of-way across a railroad has been condemned by a telegraph, telephone or street railway company, the railroad company shall be advised of the manner in which such telephone or telegraph company proposes to erect its poles and string its wires or place plant facilities underground, and in case of a street railway company, it shall give the railroad company notice of the manner in which it proposes to construct its tracks across the railroad, and if the railroad company shall object thereto, the public service commission shall have jurisdiction, upon complaint filed with it by the railroad company, to enter an order directing how the poles and wires or underground plant, if a telephone or telegraph company, shall be erected and strung or placed underground, and how tracks, if a street railway company, shall be constructed, and the railroad shall be crossed as ordered, and in no other manner.
