OSE Train, Greece

OSE (Organismos Sidirodromoi Ellados), or Hellenic Railways Organization, is Greece's national railway operator with a rich history dating back to 1920. Operating both conventional and intercity services, OSE connects major Greek cities and regions, including Athens, Thessaloniki, Patras, and Larissa, as well as smaller towns throughout the mainland. The network covers popular routes such as Athens to Thessaloniki, Athens to Larissa, and Athens to Livadeia, offering travelers scenic journeys through Greece's diverse landscapes—from coastal views to mountainous terrain. OSE trains feature comfortable seating, air-conditioning, and modern amenities designed for both short commutes and long-distance travel. The intercity services provide a reliable and affordable alternative to road travel, with regular departures throughout the day. Many routes showcase Greece's natural beauty, passing through olive groves, historic sites, and picturesque villages that make train travel a memorable experience.

In recent years, OSE has undergone significant modernization efforts to improve infrastructure, rolling stock, and service quality. The railway plays a crucial role in connecting communities, supporting tourism, and reducing road congestion across Greece. With ongoing investments in high-speed rail development and international connections, OSE continues to evolve as an essential part of Greece's transportation network, bridging the country's ancient heritage with modern European rail standards.
