New Wholesale Door-to-Door Product
In 2005, our Stacktrain unit began testing a new door-to-door transportation service offering called PacerDirect with several intermodal marketing companies, including our own wholly-owned
intermodal marketing company. PacerDirect uses both our cartage and Stacktrain operations to provide improved one-source transportation service to intermodal marketing companies and other transportation intermediaries. We will continue development and further introduction of this seamless, door-to-door product to additional third party intermediaries and markets during 2006.
