Any railroad company violating any provision of this section shall pay a penalty of one hundred dollars for each and every offense, one half of such penalty to go to any person who shall sue for it and one half to the county in which the offense occurs. Nothing herein contained shall bar any action for actual or punitive damages growing out of any violation of this section and any such causes of action may be united in the same complaint.
