A rail 13 for supporting a trolley 14 of gantry crane 10 has rail sections 18,19 on opposites sides of a joint 17 provided with end regions 20 of a modified rail head profile that directs the wheels of the trolley 14 over ridges 23 that rise gradually above the height L1 of the rail head 27 while approaching the joint 17. The ridges 23 then carry the wheels into the joint 17 where the transition from one rail section to the next occurs over reinforced region. The load-bearing apexes A of the ridges are disposed away from the side edges of the rail 13 and away from the ends of each projecting portion 21. The rail increases the operational life of a crane rail by reducing wear rate in high stress areas of the joint 17 and by adding additional wear material above the rail at the joint.
