The Budapest-Belgrade high-speed railway has been in the news for a decade. Freight trains have been running since February 27, 2026. As of June 12, 2026, passenger service has not yet started — signalling system issues pushed the launch past the original March target and past the revised June estimate.
When it does start: 3 hours 17 minutes between Budapest Keleti and Belgrade Centar, every four hours. Until then, the current route via Subotica and Szeged takes 6.5–7 hours.
That is the single most searched Eastern Europe train question of 2026, and it has no clean answer in any existing travel guide. This Eastern Europe train travel guide 2026 gives it, along with the routes that do work, the pass verdict for a Balkans trip, and the recommended circuit that uses trains where they are good and buses where they are not.

The Budapest-Belgrade Railway: What’s Actually Happening
A decade in the making, €2.89 billion, 350 kilometres of modernised track, and the most strategically significant Chinese infrastructure project completed inside the European Union.
What’s running: Freight trains, since February 27, 2026.
What’s not running yet: Passenger trains. The ETCS signalling system — the European Train Control System required for safe high-speed operation — has had testing issues on the Hungarian section. The Hungarian Ministry of Construction and Transport confirmed in March that testing could not begin until April, with at least three months to resolve issues after that. Seat61, the most reliable English-language train planning resource, has the status as: “postponed until at least June, possibly longer.”
When it launches (estimated summer 2026 at the earliest):
- SOKO trains every 4 hours, Budapest Keleti to Belgrade Centar in ~3h17m
- Eurocity services continuing to Vienna (with restaurant car)
- Passport checks expected at Kelebia (Serbia-Hungary border), potentially adding 30 minutes; studies underway for en-route passport processing
Current route (still in operation): 6.5-7 hours via Subotica (Serbia) and Szeged (Hungary), changing trains. Fare: check mavcsoport.hu and srbvoz.rs for current pricing.
The Novi Sad context: The November 2024 collapse of the canopy at Novi Sad railway station — which killed 16 people — is part of why Serbia’s rail infrastructure has faced intense scrutiny and why Novi Sad’s main station remains closed. The Belgrade-Budapest project has proceeded but domestically remains contentious. The Novi Sad station closure is why visitors day-tripping to Novi Sad must take a bus from the station area to the city centre.
Eastern Europe train travel guide 2026: Recommended Balkans Train Circuit
The Balkans rail network has honest gaps. The recommended approach: trains where they’re the best option, buses where they’re not. Trying to do the entire circuit by train adds time without adding value.
The circuit (north to south):
| Leg | Mode | Time | Notes |
|---|---|---|---|
| Budapest → Belgrade | Train | 6.5-7h (currently) / 3h17m (when launched) | Via Subotica/Szeged now; direct when high-speed opens |
| Belgrade → Novi Sad | SOKO train | ~36 min | From Prokop station; Interrail NOT valid on SOKO |
| Belgrade → Sarajevo | Bus (FlixBus/Autoprevoz) | 6-7h | No train (discontinued 2012); overnight ~€15 |
| Sarajevo → Mostar | Bus or scenic train | 2-2.5h bus / ~2.5h train | Train: scenic Neretva canyon, 1-2 daily, book at station |
| Mostar → Dubrovnik | Bus | ~3h | No train option |
| Dubrovnik → Kotor | Bus/taxi | 2h | No train |
| Kotor → Belgrade | Belgrade-Bar railway + bus | Day train in summer / overnight sleeper year-round | Podgorica → Belgrade via Belgrade-Bar railway; ~11h scenic |
The circuit also works westward from Belgrade: Zagreb (train from Belgrade) → Ljubljana (train) → Vienna (train) → Budapest (train or return).
The Routes That Work
Budapest → Belgrade
Use the current 6.5-7 hour route until the high-speed service launches. Book through mavcsoport.hu (Hungarian rail) or interrail.com. Interrail pass valid on this route.
Once the high-speed service launches: 3h17m, SOKO trains every 4 hours. Book at srbvoz.rs or station.
Belgrade → Novi Sad (Day Trip)
SOKO fast train from Beograd Prokop station (not Belgrade Centar). Journey: ~36 minutes. Fare: 500-970 RSD (~€5-9) one-way, dynamic pricing. Reach Prokop via trolleybus 41 from city centre.
Important: Interrail and Eurail passes are NOT valid on the SOKO service. Buy a ticket at the station or online at srbvoz.rs.
Novi Sad station is still closed — buses run from the station area to the city centre (Uspenska Street). Budget 10 minutes by taxi or 30 minutes on foot.
Belgrade → Bar (The Scenic Route)
The Belgrade-Bar railway is one of Europe’s genuinely great train journeys. Built in phases from 1952-1976, the line crosses the 200-metre-high Mala Rijeka viaduct — the tallest railway viaduct in the former Yugoslavia — passes through 254 tunnels and over 234 bridges, traverses the Tara Canyon area, and descends through the Black Mountains to Montenegro’s Adriatic coast.
Daytime train: Summer only. Departure Belgrade ~10:00, arrives Bar ~21:00. ~11 hours. Fare: ~€22-27 depending on class and destination.
Overnight sleeper: Year-round. Depart Belgrade ~21:30-22:00, arrive Bar ~07:00-08:00. Fare: ~€22-27 for a couchette (sleeping berth).
Reservations required — made by phone or email up to 30 days in advance. Contact: reservation numbers on srbvoz.rs or via Beograd Centar station. The overnight option is the more practical choice for most itineraries — you arrive in Montenegro in the morning and haven’t spent a hotel night.
From Bar: bus connections to Kotor (~1h, ~€5) and Budva. From Podgorica (stop before Bar): bus to Sarajevo (4h) or south toward Albania.
Sarajevo → Mostar (Within Bosnia)
The only useful domestic train within Bosnia for most visitors. The ŽFBH (Federation railway) and ZRS (Republika Srpska railway) networks run limited services. The Sarajevo-Mostar line follows the Neretva canyon — an hour of the journey tracks a turquoise river through limestone cliffs.
Journey time: ~2.5 hours. Departures: 1-2 per day (check at Sarajevo station or hbzm.ba). Booking: Station window preferred — the ZRS network has limited online booking and foreign cards sometimes rejected. Cash in KM/BAM.
The bus (2.5-3 hours, 18 daily departures, Put života 8 bus station) is more frequent and nearly as scenic on the road section. Either works; the train is the right choice if the schedule aligns and the route matters to you.
Sofia → Plovdiv and Beyond
Bulgaria’s rail network is more useful than its reputation suggests.
Sofia → Plovdiv: ~2h15m, ~€8. Trains run frequently. The most useful domestic Bulgarian leg for visitors.
Sofia → Varna: Overnight train, useful for Black Sea coast.
Sofia → Istanbul: The overnight international train — classic Balkans route. Journey ~10-12 hours. A genuinely useful international connection. Check bdz.bg (Bulgarian State Railways) for current schedules.
Sofia → Bucharest: ~9-10 hours direct. Useful for continuing into Romania.
Interrail and Eurail: When the Pass Is Worth It
For a pure Balkans itinerary (Serbia, Bosnia, Montenegro, Albania), a pass is almost certainly not worth it. Here’s why:
Bosnia: Not covered by Interrail or Eurail passes at all. The train you’re most likely to use (Sarajevo-Mostar) requires a point-to-point ticket regardless.
Montenegro: Not covered.
Serbia: Covered — but the most useful Serbia service (SOKO Belgrade-Novi Sad) is NOT pass-valid. The pass works for the Belgrade-Bar overnight and international connections.
Bulgaria: Covered. Useful for Sofia-Plovdiv and Sofia-Istanbul.
Point-to-point fares are low across the Balkans — €10-25 for most journeys. Buying individual tickets is straightforward and usually cheaper for a 2-week Balkans circuit than any pass.
When the pass makes sense: If you’re combining the Balkans with significant Western or Central European travel — Vienna, Budapest, Prague, Krakow, Zagreb, Ljubljana — the pass starts to earn back its cost on the higher-priced Western routes.
Train vs Bus: The Honest Guide
| Route | Train | Bus | Verdict |
|---|---|---|---|

| Belgrade → Sarajevo | ✗ No direct train | FlixBus/overnight ~€15 | Bus only option |
| Sarajevo → Mostar | ✓ Scenic but slow, 1-2/day | 18 buses/day, faster | Bus for flexibility; train for scenery |
| Belgrade → Bar | ✓ Overnight sleeper, scenic | Bus also runs | Train wins on experience |
| Sofia → Plovdiv | ✓ Frequent, €8 | Buses also run | Train preferred |
| Dubrovnik → Kotor | ✗ No train | Bus/taxi ~2h | Bus only option |

FAQ
Is there a direct train from Budapest to Belgrade in 2026?
Not reliably for passengers yet. The upgraded Budapest-Belgrade railway has had a delayed passenger launch, with reports in 2026 pointing to signalling and operational issues on the Hungarian section. Check Seat61’s Budapest to Belgrade train guide, the official MÁV site, and Srbija Voz before booking. Until the direct passenger service is confirmed, assume buses or indirect rail routes may still be necessary.
Is there a direct train from Belgrade to Sarajevo?
No. The direct Belgrade-Sarajevo passenger train was discontinued years ago, and the practical option is now the bus. FlixBus runs Belgrade to Sarajevo services, usually with overnight options depending on the day. For this route, treat the bus as the normal choice rather than trying to force a rail connection.
Is Interrail worth it for the Balkans?
Usually no, not for a pure Balkans trip focused on Serbia, Bosnia, and Montenegro. Interrail is useful across much of Europe, but Balkan rail coverage is patchy, cross-border trains are limited, and point-to-point bus or train fares are often cheap. Check the official Interrail railway map before buying a pass. For a broader Europe trip that also includes expensive Western or Central European rail legs, Interrail can still make sense.
What is the most scenic train journey in the Balkans?
The Belgrade-Bar railway through Serbia and Montenegro is the standout scenic train journey in the Balkans. It crosses hundreds of bridges and tunnels, including the famous Mala Rijeka viaduct in Montenegro. Use the official Srbija Voz timetable for current departures and Seat61’s Belgrade to Bar railway guide for practical ticket and sleeper advice.
Can you travel Eastern Europe by train only?
Partially. Trains work well on routes such as Belgrade-Novi Sad, Belgrade-Bar, Sofia-Plovdiv, and many Central European legs. For the Balkans circuit, buses are essential because there are no practical trains from Belgrade to Sarajevo, Sarajevo to Dubrovnik, or between most Adriatic coastal cities. The best approach is to use trains where they are strong and buses where the rail network is missing. For buses, compare routes on FlixBus; for Serbian trains, use Srbija Voz.
