Fast and effective performance of the works is essential in Railway Construction activities. In order to provide safest and most comfortable mode of transport on rails, Demiryapı İnşaat has been actively involved in renovation and construction of tracks and switches starting from ballast laying to proper assembly of rails, sleepers and fasteners as well as regular maintenance of tracks.

To make transportation more comfortable, we create a continuous length of track by means of professional flash-butt welding machines from the start point to the end point.
