Across Eastern Europe, where railways have connected cultures and communities for generations, few international train journeys are as distinctive as the Prietenia Express. Meaning “Friendship” in Romanian, this overnight sleeper service links Chișinău, the capital of Moldova, with Bucharest, Romania’s bustling capital, offering travellers far more than a simple cross-border connection. It is a journey through rolling vineyards, historic cities and fertile countryside, while also showcasing one of Europe’s most remarkable railway engineering traditions—a rare railway gauge-changing operation that takes place while passengers remain on board.
In an era dominated by high-speed trains and short-haul flights, the Prietenia Express continues to attract travellers seeking slower, more immersive journeys that reveal the landscapes, heritage and traditions of Eastern Europe.
A Rail Journey Rooted in Friendship
The name Prietenia, meaning “Friendship,” reflects the close historical and cultural ties shared by Moldova and Romania.
For decades, the train has provided an important transport link between the two neighbouring countries, connecting families, students, business travellers and tourists.
Today, it also serves as a symbol of regional cooperation while introducing international visitors to destinations that are often overlooked on mainstream European itineraries.
Its overnight schedule allows passengers to leave Chișinău in the evening and wake up in Bucharest the following morning, making efficient use of travel time.
Travelling Through Vineyards and Historic Landscapes
The route passes through some of the most picturesque scenery in both Moldova and northeastern Romania.
Travellers enjoy views of vineyards that have supported Moldova’s internationally recognised wine industry for centuries, alongside fertile agricultural landscapes, forests and traditional villages.
As the train continues towards Romania, it reaches the historic city of Iași, one of the country’s most important cultural and academic centres.
The changing scenery offers a relaxing alternative to motorway travel while providing a deeper appreciation of the region’s rural character.
The Remarkable Stop at Ungheni
What truly distinguishes the Prietenia Express is its stop at Ungheni, located near the Moldova–Romania border.
Here, the train undergoes one of Europe’s most unusual railway procedures—a gauge change.
Moldova’s railway network uses the broader 1,520-millimetre gauge, inherited from the former Soviet railway system, while Romania operates on the standard 1,435-millimetre European gauge.
Instead of requiring passengers to change trains, railway engineers lift each carriage and replace or adjust the wheelsets to match the different track gauge.
Passengers remain comfortably inside their compartments throughout the process, making it both a practical engineering solution and an unforgettable travel experience.
A Favourite Among Railway Enthusiasts
Few passenger trains anywhere in Europe offer such a visible demonstration of railway engineering.
The gauge-changing operation has become one of the Prietenia Express’s defining attractions, drawing railway enthusiasts from around the world.
For many travellers, witnessing this carefully coordinated procedure is every bit as memorable as the journey itself.
The experience also provides insight into the historic development of European railway networks and the technical challenges of international rail travel.
Comfortable Overnight Travel
The Prietenia Express offers sleeper accommodation designed to make overnight travel comfortable and convenient.
Passengers can rest throughout the journey before arriving in Bucharest ready to begin exploring Romania’s capital.
Sleeping compartments provide a more relaxed alternative to overnight road travel while allowing travellers to experience one of Eastern Europe’s classic rail journeys.
The slower pace encourages appreciation of the landscapes that might otherwise be missed from an aircraft window.
Supporting Tourism Between Moldova and Romania
The overnight train also plays an important role in regional tourism.
Visitors can easily combine Moldova’s renowned wineries, monasteries and cultural attractions with Romania’s castles, historic cities and mountain landscapes in a single itinerary.
Improved cross-border rail links encourage sustainable tourism while strengthening economic and cultural connections between the two countries.
Rail travel also appeals to environmentally conscious travellers seeking lower-carbon transport options.
Preserving the Romance of International Rail
Across Europe, overnight rail services are experiencing renewed popularity as travellers seek alternatives to short-haul flights.
The Prietenia Express demonstrates that classic sleeper trains continue to offer experiences that modern transport cannot easily replicate.
Its combination of engineering heritage, cultural history and scenic landscapes transforms a routine international journey into a memorable travel experience.
