The Rate EDI Network (REN) provides an electronic means for all North American carriers to define and publish information on rates for rail freight movement of commodities. REN allows any interline railroad or local carrier, the means to broker, negotiate and publish their own freight rates and divisions with an electronic message exchange between carriers supported by the REN application process.

All railroads that publish their rates may enter their rates electronically through their internal applications or manually via a web interface. These rates are then distributed to all parties involved in the route, or who participate in the rate, for timely and error-free exchange of electronic freight rates, divisions, and shipment condition codes. REN also assists in the exchange of how rates that are applied to a shipment will be divided among the participating carriers.
