A method and apparatus for transporting fluid or particulate material is described wherein a railroad car is placed on a truck-trailer unit and is transported over land by the truck-trailer to the source of the material. The railroad car is loaded with the material at the source of the material while the railroad car is on the truck-trailer unit and is then transported over land to a rail terminal by the truck-trailer unit. The loaded railroad car is then unloaded from the truck-trailer unit at the rail terminal for subsequent rail transportation. A second method of transporting the material is described wherein the railroad car is loaded with the material and is transported by rail to a rail terminal. The loaded railroad car is loaded onto the truck-trailer unit at the rail terminal and is transported over land to a material unloading location by the truck-trailer unit. The material is unloaded from the loaded railroad car at the material unloading station while the railroad car is on the truck-trailer unit. The truck-trailer unit comprises a wheeled frame having a folding gooseneck at the forward end which serves as an unloading and loading ramp. The ramp includes either a pair of spaced-apart rails or guides for facilitating the unloading and loading of the railroad car.
