The board of public works and the city engineer are authorized and directed to make periodic inspections of all the tracks and frogs and switches of all of the railway companies lying in, on, or across any public street, alley, sidewalk, or crosswalk, whether or not the same is laid or exists therein pursuant to ordinance, franchise and, if such inspection discloses a condition to exist within any such street, alley, or public way that creates or is a hazard to other lawful users of the street, alley, sidewalk, or crosswalk, the board of public works shall direct by registered mail to the local agent of the railway company operating or controlling the tract or right-of-way, a notice describing the condition and hazard with reasonable certainty, and direct that the same shall be repaired or placed in a state of reasonable repair within 30 days from the date of receipt of the notice. If the repairs are not made or actually commenced within the 30-day period, the board of public works shall deliver a notice in writing to the local agent of the railway company directing that the streets and alleys containing the hazardous condition not be used for railway purposes, and that no train or railway equipment be moved across or along the street after the service of notice personally on the agent until after repairs have been completed.
