Sections 4959.02 to 4959.04 of the Revised Code, relating to fences, do not apply to any case in which compensation for building a fence has been or may be taken into consideration and estimated as a part of the consideration to be paid for the right-of-way, so far as the fence has been or may be settled or paid for. Those sections do not affect, in any manner, any contract or agreement between a railroad company, or person having the control and management of a railroad, and the proprietors or occupants of lands adjoining for the construction or maintenance of fences and cattle guards.
