Adriatic Express, Warsaw, Rijeka, PKP Intercity, České dráhy, Croatia, and overnight train have become key talking points in European rail travel during the 2026 summer season. Following overwhelming public interest and rapidly sold-out promotional fares, the long-distance overnight train connecting Poland’s capital with Croatia’s Adriatic coast has returned with expanded operations, improved scheduling, and new travel options for passengers exploring Central and Southern Europe.

The seasonal rail service, operated by PKP Intercity in cooperation with České dráhy, has continued to attract travellers searching for an alternative to congested airports, lengthy security procedures, and increasingly unpredictable flight disruptions. Instead of navigating busy terminals, passengers have been offered an opportunity to experience one of Europe’s most scenic international rail journeys while travelling comfortably overnight across five countries.

As of the 2026 summer season, the Adriatic Express has evolved beyond being simply a transport connection. The route has increasingly become part of the growing slow-travel movement, where the journey itself has been embraced as an important part of the overall holiday experience.

How Has the Adriatic Express Returned for Summer 2026?

The Adriatic Express officially resumed operations on June 26, 2026, marking the return of one of Europe’s most anticipated seasonal international rail services.

The service has been scheduled to operate throughout the summer until August 28, 2026, providing passengers with a direct overnight connection between Warsaw and Rijeka during the busiest holiday period of the year. The seasonal timetable has been designed to accommodate strong demand from travellers heading towards Croatia’s Adriatic coastline while also serving passengers visiting destinations across Central Europe.

Its return has reflected the continuing popularity of international overnight rail travel as travellers increasingly seek sustainable, comfortable, and stress-free alternatives to short-haul flights.

With growing environmental awareness and renewed interest in slower forms of travel, the service has strengthened its position within Europe’s expanding network of cross-border rail connections.

Why Has Demand Been So Strong?

Interest in the Adriatic Express has exceeded expectations well before the first departure of the season.

Tickets officially became available on May 5, 2026, and the initial promotional fare allocations were sold out rapidly due to exceptionally high demand. The popularity of these discounted tickets demonstrated the increasing appetite for affordable long-distance rail travel, particularly during the peak European holiday season.

Although the lowest promotional prices disappeared quickly, standard tickets have continued to remain available for many late-summer departures. Travellers have been encouraged to verify current availability directly through the official PKP Intercity Booking Platform, where real-time ticket inventories continue to be updated throughout the operating season.

The sustained demand has highlighted the growing confidence of European travellers in international rail as a practical holiday option.

How Frequently Does the Train Operate?

One of the most significant improvements introduced for the 2026 season has involved increased service frequency.

The Adriatic Express now operates six days each week, running daily except Saturdays. This represents a substantial enhancement compared with the previous summer, when the service operated only four times per week.

The expanded timetable has provided travellers with greater flexibility when planning extended holidays, weekend breaks, or multi-country rail journeys. It has also improved capacity during one of Europe’s busiest tourism periods, helping accommodate rising passenger demand without significantly increasing waiting times between departures.

The additional departures demonstrate the confidence of PKP Intercity and České dráhy in the continued growth of seasonal international rail travel.

How Long Does the Journey Take?

The overnight journey between Warsaw and Rijeka has also benefited from operational improvements introduced for 2026.

Thanks to routing optimisations, the total travel time has been reduced to approximately 18 to 19 hours, shortening the journey by roughly one hour compared with the previous season. Although the route remains one of Europe’s longest seasonal rail services, the overnight schedule allows much of the travel time to pass while passengers are resting.

Departures from Warsaw take place at approximately 2:00 PM, while arrivals into Rijeka are scheduled for around 10:00 AM the following morning.

The carefully planned timetable enables passengers to maximise their holiday time by arriving directly at the Adriatic coast without losing valuable daytime hours to travel.

Which Countries Does the Adriatic Express Cross?

The Adriatic Express offers one of the continent’s most scenic international rail journeys.

Over the course of approximately 1,240 kilometres, the train travels through five European countries before reaching Croatia’s Adriatic coastline. Beginning in Poland, the route continues across Czechia before entering Austria, Slovenia, and finally Croatia.

Rather than spending hours inside airport terminals, passengers are treated to continually changing landscapes visible directly from their carriage windows. The route provides memorable views of several important European cities, including Vienna and Ljubljana, while also passing through picturesque countryside, mountain scenery, and river valleys.

The journey has increasingly become appreciated not only for its destination but also for the rich travel experience offered throughout the route itself.

Why Is Overnight Rail Becoming More Popular?

The growing success of the Adriatic Express reflects broader changes taking place across European tourism.

Increasing numbers of travellers have begun embracing slow travel, placing greater value on comfort, scenery, convenience, and environmental sustainability than on simply reaching a destination as quickly as possible. Overnight rail has become particularly attractive because accommodation and transportation are effectively combined into a single journey.

The service also enables passengers to avoid many of the inconveniences associated with air travel, including lengthy airport security procedures, baggage restrictions, delayed departures, and congestion during the peak holiday season.

Instead, travellers are able to relax, sleep, dine, and enjoy panoramic scenery while steadily moving towards the Adriatic coast.

This renewed interest has contributed to the revival of several international overnight rail routes across Europe during recent years.

What Ticket Options Are Available?

Despite the rapid sale of promotional fares, passengers continue to have several ticket choices available throughout the season.

Base second-class seated tickets begin at approximately €44.90, offering one of the most affordable international rail journeys currently available across Central Europe. Travellers seeking additional comfort may instead choose couchette sleeper accommodation, with one-way berths generally priced between €69.90 and €89.90.

These sleeper compartments allow passengers to rest throughout much of the overnight journey before arriving refreshed in Rijeka the following morning.

Depending upon travel dates and remaining availability, passengers can continue checking fares through the official PKP Intercity Booking Platform for departures operating later in the summer season.

What New Routes Have Been Added for 2026?

One of the most significant enhancements introduced this year has been the expansion of onward travel options after reaching Slovenia.

When the Adriatic Express arrives in Ljubljana, the train now divides into two separate sections. One portion continues directly towards Rijeka, maintaining the traditional Croatian destination. Meanwhile, a newly introduced coach detaches and proceeds to Koper, Slovenia’s principal Adriatic port city.

This operational change has expanded the geographical reach of the service while creating additional holiday opportunities for travellers wishing to explore Slovenia’s coastline.

The enhancement has transformed the Adriatic Express from a single-destination seasonal service into a broader gateway for exploring multiple Adriatic destinations.

How Has Trieste Become Easier to Reach?

Beyond the new Koper connection, travellers have also been provided with improved access to Italy.

Passengers now have the option of purchasing combined tickets that include a dedicated bus transfer from Ljubljana directly to Trieste. This integrated connection has simplified travel planning by enabling passengers to continue seamlessly towards northeastern Italy without arranging separate transport independently.

The combined ticket option reflects increasing cooperation between transport providers as they seek to create more flexible cross-border travel experiences throughout Europe.

This additional connection has significantly broadened the appeal of the Adriatic Express for travellers planning multi-country itineraries across the Adriatic region.

What Does the Adriatic Express Mean for European Tourism?

The return of the Adriatic Express for summer 2026 represents more than the revival of another seasonal railway. It highlights the continued resurgence of international overnight rail travel as travellers increasingly prioritise convenience, sustainability, affordability, and memorable travel experiences.

Operated jointly by PKP Intercity and České dráhy, the service successfully connects Warsaw with Rijeka while traversing Poland, Czechia, Austria, Slovenia, and Croatia across a scenic 1,240-kilometre route. The improved six-day weekly schedule, shorter journey time, expanded onward connections to Koper and Trieste, and continued popularity among holidaymakers all demonstrate the growing importance of cross-border rail travel within Europe.

As promotional fares continue selling rapidly and passenger demand remains exceptionally strong, the Adriatic Express has firmly established itself as one of the standout rail journeys of the 2026 summer season, offering travellers an attractive alternative to air travel while showcasing the beauty of Europe’s diverse landscapes along the way.
