Every railroad corporation carrying passengers in cars propelled by steam, which shall collect in the cars a greater fare than the price for which a single passage ticket is sold from the station at which the passenger takes the train, shall issue to the passenger a certificate for such sum as the fare collected on the train exceeds the sum for which a single passage ticket for the same distance is sold at the ticket office of the company, which certificate shall be payable upon presentation at any ticket office of the corporation; and every railroad corporation that shall neglect or refuse to comply with the provisions of this section shall be fined not less than fifty dollars ($50.00) nor more than five hundred dollars ($500) for each offense, one-half (½) to the use of the complainant and one-half (½) thereof to the use of the state.
