The present invention relates generally to railroad car configurations and assemblies, more specifically but not by way of limitation, a railroad car system that includes a novel railcar configured to have operably coupled thereto a refrigerated container, commonly known as reefers, wherein the present invention deploys a railcar having improved electrical configuration so as to enable additional alternate configurations of reefers.
Thousands of miles of railroad are dispersed across North America. Railroads are heavily utilized as a mode of commercial transportation for items such as but not limited to automobiles, bulk goods and large construction equipment. Another item that is transported by rail are perishable goods such as but not limited to food. These perishable goods must be shipped in refrigerated containers in order to inhibit the spoiling of the goods during transportation. Most commonly the perishable goods are stored in containers commonly referred to as reefers. The typical configuration of a reefer is either a twenty-foot container or a forty-foot container. These aforementioned containers have the necessary refrigeration in order to maintain the interior volume at a desired temperature so as to prevent spoilage of the perishable goods during transportation.
The conventional assembly of railcars will include a plurality of platform cars and a generator car that supplies the necessary electrical power to operate the refrigeration of the reefers. The problem with conventional platform railcars is their existing wiring configuration and its inability to both adapt to alternate reefer configurations as well as facilitate efficient deployment of the electrical connections and/or wiring.
