A railroad or branch or extension of a railroad must not be opened for public use until the Office of Regulatory Staff, after an examination, certifies that all laws relating to the construction thereof have been complied with and that the road appears to be in a safe condition for operation, unless the Office of Regulatory Staff, after ten days' written notice to it by the railroad company of such proposed opening, fails to make an examination.
