Any railroad company or corporation operating a line of railroad in Kansas failing or neglecting to comply with Kan. Stat. Ann. § 66-273, and amendments thereto, shall be guilty of a misdemeanor, and upon conviction shall be punished by a fine as follows: One hundred dollars if the blocking is for more than 10 minutes but less than 20 minutes; $300 if the blocking is for more than 20 minutes but less than 30 minutes; $600 if the blocking is for 30 minutes and $600 for each additional 30 minutes if the blocking is for more than 30 minutes. No member of a railroad train, yard, or engine crew shall be held personally responsible or found guilty of violating any state laws or any municipal ordinances regulating or intended to regulate the occupying or blocking of any street, road or highway crossing-at-grade by trains or passenger or freight cars upon reasonable proof that such person’s action was necessary due to circumstances beyond such person’s control, or to comply with the order or instructions, either written or verbal, of the person’s employer or officers or supervisory officials. Nothing in this section shall relieve the employer or railroad from any responsibility placed upon such employer or railroad by any such state law or any municipal ordinance.
