S.C. Code § 58-17-2520
Any railroad company doing business in this State shall be required to furnish the owner or shipper, or their agents, full information concerning the shipment, movement and delivery of livestock when en route and on said company's line or in said company's possession. If the company cannot make the time published in its schedule it must, whenever as much as three hours behind schedule time, wire the owner and agent at destination the extent and cause of the delay and advise him of the expected time of arrival. Upon failure to furnish such information and upon failure to give the shipper benefit of the best connection as published in its schedule, the railroad company shall pay a fine of not more than twenty-five dollars.
Nothing herein contained shall interfere with the transmission of train orders. In the event of a failure upon the part of any common carrier to give the information herein required, it shall be incumbent upon such common carrier affirmatively to show that such failure was due to the necessary use of its wire or wires for the transmission of train orders.
