History of Sakarya Regional Directorate

Railway transportation, which started in 1866 in our country, has been carried out for many years with vehicles, all of which were imported and whose maintenance and repairs were carried out in an externally dependent manner. This situation has continuously caused problems and interruptions in railway operations and increased costs. The first facilities of today's TÜRASAŞ Sakarya Regional Directorate, formerly known as TÜVASAŞ, were put into operation on October 25, 1951 under the name of "Wagon Repair Workshop" in order to eliminate these problems.
