Slovenia’s Rail Network Expands: 26 New FLIRT Trains
Slovenia’s rail network just got a major upgrade! 52 new FLIRT trains are boosting capacity and cross-border connectivity – learn how this innovative fleet is transforming travel.

Slovenia Expands its Rail Fleet with Additional FLIRT Trains
This article delves into the significant expansion of Slovenia’s railway network through a substantial order of additional FLIRT (Fast Light Innovative Regional Train) multiple units from Stadler Rail. The Slovenian state railway operator, Slovenske Železnice (SZ), has exercised an option within a pre-existing contract, committing to the purchase of 26 more trains, bolstering its existing fleet and significantly enhancing its capacity and operational capabilities. This decision reflects a strategic commitment to modernizing Slovenia’s rail infrastructure, improving passenger comfort, and increasing cross-border connectivity with neighboring countries. The investment, exceeding €150 million, showcases a commitment to sustainable and efficient transportation solutions, emphasizing the importance of rail as a crucial component of Slovenia’s national transport system. This expansion will not only enhance domestic travel options but also play a key role in fostering regional cooperation and trade through improved cross-border passenger services.
Modernizing Slovenia’s Rail Network
The initial order of 26 FLIRT trains, placed in April of the previous year, laid the groundwork for this expansion. This latest order brings the total number of FLIRT trains in the SZ fleet to 52. The mix of single and double-deck trains ordered demonstrates a strategic approach to meeting diverse passenger demands and operational requirements. The order comprises 16 three-car diesel-multiple units (DMUs) and 10 four-car electric multiple units (EMUs). This diverse fleet enables SZ to operate efficiently across varying rail lines and geographical locations.
Enhanced Cross-Border Connectivity
A key feature of these new trains is their ability to operate seamlessly across national borders. Both the DMUs and EMUs are certified for operation in Slovenia, Croatia, and Austria. This interoperability is crucial for facilitating cross-border passenger services, boosting regional tourism, and promoting economic integration within the broader Central European region. This signifies a significant advancement in regional rail cooperation, emphasizing the potential for streamlined passenger transit and economic benefits.
Technological Advancements and Operational Capabilities
The three-car diesel-electric FLIRT DMUs are designed for regional operations and reach a maximum speed of 140 km/h (87 mph). Their configuration includes an additional car module and a power pack housing the diesel engines and part of the drive equipment. The four-car electric FLIRT EMUs, reaching a maximum speed of 160 km/h (99 mph), are equipped with three different power systems, enhancing their adaptability to the varied power supply networks across different countries. This technological sophistication allows for optimal performance across the varying infrastructure of the region.
Conclusion
The decision by Slovenske Železnice to expand its fleet by ordering an additional 26 FLIRT trains from Stadler represents a significant milestone in the modernization of Slovenia’s railway system. This €150 million investment demonstrates a clear commitment to improving passenger transport within Slovenia and enhancing cross-border connectivity with neighboring countries. The strategic mix of diesel and electric multiple units, designed for interoperability across multiple national networks, reflects a sophisticated approach to optimizing operational efficiency and meeting diverse transport needs. The introduction of these modern, high-speed trains is expected to significantly improve passenger comfort, safety, and overall travel experience. The ability of the trains to operate across borders not only improves travel opportunities but also fosters economic development and integration within the wider Central European region. The expected commencement of operations in October 2021 marks a significant step towards a more efficient, sustainable, and integrated rail network in Slovenia and beyond. This initiative serves as a compelling example of how strategic investment in modern railway infrastructure can significantly contribute to economic growth, improved regional connectivity, and a more sustainable transportation future. The success of this expansion will undoubtedly serve as a model for other rail operators seeking to modernize their fleets and enhance cross-border collaboration.
