A rail carrier providing transportation or service subject to the jurisdiction of the Board under this part may not enter a combination or arrangement to prevent the carriage of freight from being continuous from the place of shipment to the place of destination whether by change of time schedule, carriage in different cars, or by other means. The carriage of freight by those rail carriers is considered to be a continuous carriage from the place of shipment to the place of destination when a break of bulk, stoppage, or interruption is not made in good faith for a necessary purpose, and with the intent of avoiding or unnecessarily interrupting the continuous carriage or of evading this part.
