((2)) promptly made available in electronic form.

((c)) A rail carrier may not increase any common carrier rates or change any common carrier service terms unless 20 days have expired after written or electronic notice is provided to any person who, within the previous 12 months—

((2)) has made arrangements with the carrier for a shipment that would be subject to such increased rates or changed terms.

((d)) With respect to transportation of agricultural products, in addition to the requirements of subsections (a), (b), and (c), a rail carrier shall publish, make available, and retain for public inspection its common carrier rates, schedules of rates, and other service terms, and any proposed and actual changes to such rates and service terms.
