TÜLOMSAŞ

TÜLOMSAŞ, formally Türkiye Lokomotif ve Motor Sanayi Anonim Şirketi, was a Turkish railway-industry manufacturer headquartered in Eskişehir. Its principal activities centered on the construction and assembly of locomotives, railway wagons, and diesel engines. The company served as the main locomotive supplier for the Turkish State Railways and was an important part of Turkey’s domestic railway-manufacturing capability. The company operated in a sector shaped by state railway investment, domestic industrial policy, and the need to maintain and expand Turkey’s rail fleet. Its product scope included locomotive manufacturing and railway-related industrial production rather than consumer-facing goods. TÜLOMSAŞ was also one of the Turkish companies involved in designing and assembling locomotives domestically. In addition to its own manufacturing activities, it developed industrial partnerships, including an arrangement with GE Transportation under which it built GE PowerHaul locomotives. Eskişehir was central to the company’s identity and operations: its headquarters and factory were located there, making TÜLOMSAŞ one of the city’s significant industrial institutions. The company’s role connected domestic engineering and production with the requirements of the Turkish State Railways and with international locomotive technology supplied through partnerships. TÜLOMSAŞ ceased to exist as an independent company on May 4, 2020, when it was merged with TÜVASAŞ and TÜDEMSAŞ. The three organizations were consolidated to form TÜRASAŞ, Turkey’s national rail systems manufacturing entity. Consequently, TÜLOMSAŞ is best understood today as a former Turkish state railway-industrial brand and manufacturing organization whose capabilities and institutional legacy were incorporated into TÜRASAŞ.

TÜLOMSAŞ was a Turkish railway manufacturing company based in Eskişehir. Its formal name, Türkiye Lokomotif ve Motor Sanayi Anonim Şirketi, reflected its principal industrial functions: locomotive production and the manufacture of railway-related machinery and diesel engines. The company operated within Turkey’s state-oriented railway industrial structure and became the main locomotive supplier to the Turkish State Railways. Its factory and headquarters in Eskişehir made it an important center for railway engineering and heavy manufacturing in Turkey. TÜLOMSAŞ produced and assembled locomotives and railway wagons, while also contributing to the domestic design and assembly of locomotives. It was identified as one of two Turkish companies involved in locomotive design and assembly, alongside EUROTEM. The company also pursued international industrial cooperation. Through a partnership with GE Transportation, TÜLOMSAŞ built GE PowerHaul locomotives. This arrangement linked the company’s domestic manufacturing base with an internationally developed locomotive platform and demonstrated its role as both a Turkish railway supplier and a manufacturing partner for global railway technology. TÜLOMSAŞ remained associated with Turkey’s railway modernization and locomotive supply requirements until a national restructuring of railway manufacturing. On May 4, 2020, it was merged with TÜVASAŞ and TÜDEMSAŞ. The three companies were combined to create TÜRASAŞ, bringing their manufacturing capabilities under a single national rail-systems organization. After that merger, TÜLOMSAŞ no longer operated as an independent corporate entity, although its Eskişehir facilities and industrial expertise formed part of the broader institutional legacy transferred to TÜRASAŞ.
