A procedure for laying railway tracks on a trackbed on which sleepers (20) are located, that comprises at least the following steps: a) approach of a track laying train (30) with the stretches of rail (1) to be laid in the laying area; b) joining of the pairs of rails (1) to the consecutive rails (1) by means of tractor plates (200); c) unloading the pairs of rails (1) from the track laying train (30) onto the bed; d) squaring of the sleepers (20) by means of a squaring device; e) joining of the consecutive pairs of rails (1) by means of a joint plate (100); f) unloading of ballast in hoppers onto the bed; g) tamping of the rails (1); h) profiling of the ballast by means of a profiling device (400); i) welding of the rails (1).

A method and a device for laying a rail for rail transit are provided. In the present method for laying a rail for rail transit, the rail is a steel rail, which is fabricated and laid continuously on site; the on-site fabrication of the steel rail adopts at least on-site rolling; the rolling is continuous rolling; there is also a casting process before the steel rail is rolled; and the casting process is a continuous casting process. Through the continuous casting and rolling processes, the rolled steel rail is in a continuous state. The continuous steel rail is laid directly after being fabricated by the continuous casting and rolling processes. By improving the existing equipment, the present disclosure transfers the fabrication process of the steel rail to the rail laying site and directly lays the steel rail into a continuous seamless rail.

A support device (10) for a replacement rail (RA) intended to be made integral with a running rail including a first part with removable fastening means (A1) for attachment to a foot (P) of a running rail (RC), and a second part (B) for receiving a replacement rail. The second part is rotatable about an axis (X) relative to the first part (A) and includes two lateral portions (B3, B4) extending in a first longitudinal direction (L1) parallel to the axis of rotation. The two lateral portions (B3, B4) each being designed to bear on a sleeper (T), the second part (B) including a lock for a replacement rail (RA) in at least one second direction (L2) perpendicular to the first longitudinal direction (L1).

Dynamic energy transfer (DET) systems are costly and time-consuming to install. Accordingly, an installation system is disclosed that comprises stowage for rail segments and poles, two strategically positioned cranes, and/or strategically positioned platforms, to enable less expensive and faster installation of the various components of a DET system. Installation, utilizing the installation system, can significantly decrease the cost of installation, while increasing the rate of installation and maintaining safety.

A hydraulically powered railroad tie handler can be attached to a crane on the rear of a truck which can travel either over rails or over pavement. The tie handler has seven hydraulic functions: clamping a main body to underlying rails, gripping a new or old railroad tie, stroking to move the gripped tie laterally under the rails, pivoting the stroker relative to the main body of the tie handler angle the stroker path relative to the main body, tilting of the gripper head relative to the stroker, pivoting the main body to change its angle with respect to the crane attachment plate; and lifting of the main body and clamped rails by pushing off ground between the rails. The stroker extends between two spaced plate portions of the main body.

A method and system provide the ability to align a railway track. Survey representing the track are obtained. A centerline of the railway track and curvatures are autonomously computed based on the survey points. Geometry is detected based on the curvature plot and provides for geometry types including a tangent, a spiral, and a curve. An alignment is displayed and includes a curvature plot that includes the detected geometry with each geometry type displayed in a visually distinguishable manner. Parameters of the detected geometry are changed and the alignment is dynamically updated. The alignment is then exported to a physical machine that aligns the railway track consistent with the alignment.
