Ohio Rev. Code § 5561.14
In case the tracks of any street or interurban railway company cross, on a state or intercounty highway, the right of way of any railroad company at a point where, under the plans and specifications as provided for in section 5561.04 of the Revised Code, it has been determined to construct improvements, the board of county commissioners, by resolution, may require such street or interurban railway company to bear a reasonable portion of the cost assumed by the county in making the improvement, not exceeding twenty-five per cent of the portion payable by the county. The board shall have a right of action against such company for that part of the cost which the resolution requires it to bear. Such cost shall be a lien upon all the property, real and personal, of such company, situated in such county, from and after the date of the passage of the resolution.
The board may, by resolution, provide the mode and time of payment for the proportion of the cost of such improvement to be borne by the company.
Such company shall keep in repair, at its own expense, all its tracks affected by the improvement, and shall bear a reasonable proportion of the cost of maintaining, renewing, and repairing all construction work necessary to support the tracks.
