The Class 46 electric locomotive, known as the “Promat,” is one of the most iconic locomotives developed to serve the railway networks of Eastern Europe, particularly Romania. It emerged as a result of post-war technological innovation, addressing the growing need for efficient and modern railway transportation. Type of Current: Powered by 25 kV AC, 50 Hz. Power Output: Approximately 4400kW, allowing it to haul heavy trains. Maximum Speed: 160 km/h, making it suitable for rapid and intercity trains. Modular Design: It featured a robust, easy-to-maintain chassis and reliable electrical components.

In the 1970s and 1980s, Romania heavily invested in its railway infrastructure, focusing on electrifying major routes and increasing freight and passenger transport capacity. The Class 46 was designed through a combination of local expertise and external influence: International Collaboration: Romanian engineers leveraged knowledge from Swedish ASEA technology, which had also influenced earlier models like Class 43 and Class 44. Local Production: The locomotives were assembled at the ElectroputereCraiova plant, a hub for rolling stock manufacturing in Romania. Technical Specifications The Class 46 was built to be versatile, capable of operating on various electrified routes for both passenger and freight services.

Initially, the Class 46 locomotive was deployed on key Romanian routes such as: European Corridor IV: Bucharest -Brașov-Sighișoara-Arad, for fast passenger trains. Freight Transport: On industrial routes, with the capacity to haul heavy trains efficiently. Over time, the Class 46 became a staple of the Romanian Railways (CFR), appreciated for its reliability and low operating costs. The “Promat” Nickname The “Promat” name originates from the company that supplied the primary electrical components for certain series of this locomotive. This reflects the collaboration between various industry entities to create a high-performance locomotive.
