A number of attempts were made during the mid-19th century to ship agricultural products via rail car. As early as 1842 the Western Railroad of Massachusetts was reported in the June 15 edition of the "Boston Traveler" to be experimenting with innovative freight car designs capable of carrying all types of perishable goods without spoilage. The first known refrigerated boxcar or "reefer" entered service on the Northern Railroad (or NRNY, which became part of the Rutland Railroad) in June 1851. This "icebox on wheels" was a limited success in that it was only able to function in cold weather. That same year, the Ogdensburg and Lake Champlain Railroad (O&LC) began shipping butter to Boston in purpose-built freight cars, utilizing ice to cool the contents.
