发明名称 A PERMANENT WAY WITH CROSS SLEEPERS
摘要 Each tie of a railroad track has flexurally stiff bracing elements extending in the direction of the track rails into both adjacent cribs. The bracing elements extend along the axis of symmetry extending longitudinally centered between the rails and/or under the rails. Preferably, two or more adjacent ties with the bracing elements are formed into a unit, for instance a cast reinforced concrete unit.
