Services

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.

We carry out reliable, proper and cost-effective maintenance works throughout Turkey with our professional team and all necessary machinery and equipment to ensure safety in the long term. We continue to exhibit our difference and provide the best service in this sector for years by means of our grinding machines giving a visual feast during the night works to extend the life of new tracks and maintenance of the existing tracks.

Domestic and national production is one of the important policies adopted by our country making efforts to popularize.

With our desire to produce and experienced staff, we continue to produce track machines and catenary machines in our plant, with undeniable contribution to the economy. We aim at becoming the best in this field by enlarging our production scale in the future.

With development of the railway sector in our country, the electrification works have also gained importance and momentum. Installation of electrification systems is needed for more affordable, more comfortable and safer transportation. In this context, we have established our electrification unit in 2013 and successfully completed all works from post foundations and electrification installations to energization and commissioning of the system in all projects we have undertaken.
