Louis Brandeis, Davis v. Cornwell — Opinion of the Court
“ The agent's promise that the cars would be available on the day named was introduced to establish an absolute obligation to supply the cars, not as evidence that the shipper had given due notice of the time when the cars would be needed, or as evidence that the carrier had not made reasonable efforts to supply the cars. The obligation of the common carrier implied in the tariff is to use diligence to provide, upon reasonable notice, cars for loading at the time desired. A contract to furnish cars on a day certain imposes a greater obligation than that implied in the tariff. ”
