A trailer hitch arrangement for road trains 100. A first trailer 10,20,30 is connectable by a drawbar 50 to a second trailer 20,30,40 positioned behind the first trailer with a first or front end 51 of the drawbar attached to the first trailer at a location ahead of a rearmost axle 60 of the first trailer. A prime mover 90 and two or more trailers 10,20,30,40, of the road train can have a drawbar connected between each of the adjacent trailers, with the front end of the drawbar attaching to the trailer in front at a location ahead of the axis if the rearmost axle of that more forward trailer. At the front end 51, the drawbar 50 is pivoted at two points, namely P2 which is the turning pivot between the drawbar 50 and the second trailer and P3 which is the rolling pivot between the drawbar 50 and the second trailer. A pivot axis A2 extends vertically for the drawbar 50 to rotate in a horizontal plane. A pivot axis A3 extends longitudinally to allow the drawbar 50 to rotate in a lateral roll plane relative to the second trailer dolly 25. A rear end 52 of the drawbar 50 is pivotally attached to the second trailer dolly 25 at pivot P1. P1 has a pivot axis Al extending laterally in order to cause to allow the drawbar 50 to rotate in a vertical plane thereby permitting vertical movement of the trailer dolly 25 and the drawbar 50. The drawbar can have a curved gooseneck shape. C\) u LI)O e 0e
