• TÜVASAŞ (TURKISH WAGON INDUSTRY INC.)
Adapazarı traction engine workshop, the construction of which had been started in 1948 and commissioned in 1951 for the purpose of repairing the freight and passenger cars of our establishment, was carrying out the repair of 1200 freight and 600 passenger cars at that time. The railway business that was completely performed with foreign wagons relieved with the construction of this workshop. It had continued serving as a repair workshop for 10 years. During this period, the domestic wagon production was put on the agenda due to the repair problems of foreign wagons. The establishment had been transformed into Adapazarı Railway Factory with this idea and it started the domestic passenger car manufacturing in 1961.
With the tenacity and success of Turkish engineers, workers, and managers, it was started to deliver Pullman, restaurant, sleeping, suburban, and other cars at a great pace despite of the limited financial circumstances of those days. Therefore, wagons were no more imported. Within a short period, our national wagon fleet completely consisted of domestic wagons.
In 1975, the production of (UIC-RIC) passenger cars in accordance with the international standards was initiated in the company named ADAPAZARI Wagon Industry Establishment (ADVAS) at that time. Later on, RIC-X type long wagons were produced and put into service in domestic and international lines.
The establishment that does not have a competitor in our country and in neighbouring countries became an incorporated company in 1986 and obtained its current status and since then it has been serving under the trade name of TÜVASAŞ (Turkish Wagon Industry Inc.).
TÜVASAŞ, which continues its activities as an “Affiliated Corporation” of the Directorate-General of TCDD (Turkish State Railways) and its capital of which is completely owned by the state, is managed by the Board of Directors and a General Manager. The company that is composed of different technical and administrative units has a rail network of 45 km and a covered area of 76.248 square meters located on a total available area of 750.000 square meters.
Currently, 1100 permanent workers and approximately 400 managers and officials are employed in TÜVASAŞ. As the manufacturer of nearly 1.200 passenger cars in our establishment, TÜVASAŞ performs the repair and maintenance of all of these cars. All of the compartment and saloon type main line passenger cars, long and middle distance suburban wagons, electric trains, restaurant, buffet and special wagons of our establishment are the products of TÜVASAŞ. Recently, the rail buses manufactured completely by domestic projects also continue to be operated. In 1970s, 77 narrow gauge line passenger cars were exported to Bangladesh. In 1990, 30 units of bogie were exported for these cars and they still serve in this country efficiently.
Our company, which can manufacture all kinds of railway transportation vehicles with its knowledge and experience of more than 45 years, has put into service the modern cars of the year 2000 that includes the latest innovations in the world, TVS 2000 series.
