The KHŽ Class 470 electric locomotive developed for Royal Holyn Railways (KHZ), based on the ABB TRAXX platform. Introduced in the early 2000s, it became the backbone of Holynia’s freight operations, marking a significant leap in the modernization of the country’s rail fleet. With approximately 500 units produced, the Class 470 remains a vital component of KHZ’s logistics network.
Designed specifically for freight services, the Class 470 also possesses the flexibility for occasional mixed-traffic use, ensuring its utility across a variety of operational needs.
Development
The introduction of the Class 470 was part of Holynia’s strategy to revamp its rail freight capabilities during a period of economic growth and industrial expansion. By the 1990s, KHZ required a new generation of locomotives to replace aging models that struggled with the demands of modern freight transport.
KHZ collaborated with ABB (later part of Bombardier) to adapt the TRAXX platform to Holynian rail conditions. The resulting Class 470 was tailored for Holynia’s 25 kV 50 Hz AC overhead electrification system and optimized for long-haul freight operations. Its combination of power, reliability, and efficiency made it a natural fit for the country’s expanding rail network.
Design
The KHZ Class 470 combines advanced engineering with practical features to meet the rigorous demands of freight transport in Holynia. It features a Continuous power output of 5,600 kW, enabling the locomotive to haul heavy freight loads with ease. Optimized for starting heavy trains and maintaining consistent performance on steep gradients.It operates with a maximum speed of 140 km/h, sufficient for both freight services and occasional passenger duties.
Its modular design simplifies maintenance, allowing components to be easily replaced or upgraded, thus extending the locomotive’s service life. A modern cab design with advanced control systems ensures ease of use, safety, and comfort for operators.
History
Production of the KHZ Class 470 began in 1998 at the Holyn Locomotive Works under license from ABB. By the time production concluded in the mid-2000s, 500 units had been delivered to KHZ, making it one of the largest single locomotive classes in Holynia’s rail history.
The Class 470 was deployed across the country to handle:
- Heavy freight operations: Transporting bulk goods such as coal, steel, and raw materials.
- Intermodal freight services: Connecting ports, industrial hubs, and distribution centers.
- Cross-country freight corridors: Supporting long-haul logistics in Holynia’s vast rail network.
While primarily focused on freight, the Class 470 is occasionally utilized for passenger services in emergency situations or during peak travel periods. Operational History
Since its introduction, the Class 470 has proven to be one of the most reliable and efficient locomotives in KHZ’s fleet.

The locomotive's durability and ease of maintenance have allowed it to remain in active service for over two decades, with many units still performing at a high level. KHZ has periodically upgraded the fleet to incorporate modern technology, ensuring the Class 470 remains competitive with newer locomotives.
Current status
The KHZ Class 470 represents a major milestone in Holynia’s railway history. By adopting the advanced TRAXX platform, KHZ not only modernized its freight operations but also set a standard for reliability and efficiency in Holynian rail transport.
As of 2024, the Class 470 remains a cornerstone of KHZ’s freight operations, reflecting the success of Holynia’s efforts to build a robust and modern rail network. The locomotive's enduring performance and adaptability have cemented its legacy as one of the most important locomotives in KHZ’s history.
