    摘要: A device for aligning rail ends for welding of the abutting rail ends comprises a pair of clamping members which extend across from the rail to be welded to the adjacent continuous portion of rail including a telescopic member which can be expanded to abut plates at the ends thereof with the web of the rail and clamping members which extend over and around the rail to clamp the other side of the web. A jacking screw acts to lock the telescopic member in the required gauge spacing and also to jack the clamping member upwardly to locate the rail end at the required elevation.

    摘要: A railroad bed assembly for supporting thereon metallic railroad tracks is formed with a base structure which consists essentially of reinforced concrete made as prefabricated blocks with the base structure including a slab section adapted to be installed over a ground formation at the railroad bed site and with at least one upwardly extending projection running transversely to the direction of the tracks and having a trapezoidal cross sectional configuration taken in a plane extending parallel to the tracks. The projection and the slab are integrally formed of prestressed concrete material and the projection extends to form a cross tie for supporting thereupon the tracks.
