No railroad company shall discriminate in its rates or tariffs for freights in favor of any line or route connected with it as against any other line or route; nor, when a part of its own line is sought to be run in connection with any other route, shall such company discriminate against such connecting line or in favor of the balance of its own line. Rather, such company shall charge the same rates for all and shall afford the usual and customary facilities for interchange of freights to patrons of all routes or lines alike. Any refusal of the same shall afford a right of action similar to that provided in Code Section 46-9-212.
