A bill to amend the Sherman Act to prohibit a rail carrier from denying to shipper of certain bulk commodities, with intent to monopolize, use of its track which affords the sole access by rail to such shippers to reach the track of a competing railroad or the destination of shipment.

Amends the Sherman Act to prohibit any rail carrier, with intent to monopolize, from denying a person the use, at reasonable terms, of a facility which is the sole facility for movement of such person's shipment of bulk ore, coal, or grain to the tracks of a competing carrier or to the destination of shipment. Declares that a carrier shall be conclusively presumed to have denied use of such facility with intent to monopolize if it denies use of such facility at reasonable terms to such a person and to other carriers for the transportation of such person's goods.
