<p>The method involves forming holes (4) for fastening devices on beams (2) in the center between rails (1) of a railway track, and forwardly moving a boring carriage (6) on the rails by using a motor-driven drive. Front and rear sensors i.e. inductive sensors, are provided for detecting position of the beams. The carriage is stopped and subsequently operated when the sensors detect the position of the beams, where the carriage is provided with a boring device (5) and a connection device for the fastening devices. The rails are fastened to the beams by sleeper screws.</p> |
