The Summer Night Train — Osijek to Split

Croatia's far east is its flattest, quietest corner. Slavonia is the black-earth plain between the Drava and the Sava — maize and sunflowers to the horizon, oak woods that were felled for Venetian ships and Hungarian railway sleepers, storks on the chimneys of villages strung along a single street. At 18:44 on a summer evening a train leaves Osijek, the city on the Drava twenty-five kilometres upstream of the Danube, and spends the last of the light crossing it: Bizovac, Našice, Đurđenovac, with the wooded ridge of Papuk standing off to the south, then Slatina and Virovitica and the long run west through Pitomača and Kloštar in the dark.

Twelve hours later the windows show something else entirely. The train comes down out of the Dalmatian hinterland at first light, past Knin and Perković, and turns along the bay of Kaštela — seven old villages on the waterline, the Kozjak ridge behind them, the Adriatic opening to the south — and stops at Split at 08:49, a few minutes' walk from Diocletian's palace and the ferry berths. Fourteen hours and five minutes, one seat, no changes: the plain at dusk and the sea at breakfast.

The country joins up for nine weeks a year

This is a train that exists for a season and then stops existing. In the 2026 timetable it runs from Saturday 27 June to Friday 28 August southbound, and from Sunday 28 June to Saturday 29 August coming back. That is sixty-three days — nine weeks exactly — and for the other forty-three weeks of the year there is no through train between eastern Slavonia and the Adriatic at all. The journey is still possible, on an ordinary ticket with a change at Zagreb, but the single seat from one end of the country to the other is a summer thing.

It is also a fairly recent thing. HŽPP brought the through train back for the summer of 2022; the operator's president, Željko Ukić, said at the time that the last direct Osijek–Split train had run "back in the nineties", and that the point of the project was to connect continental Croatia to the coast again. Before that, Slavonian passengers travelled in through carriages attached to the Zagreb night train — the Croatian transport ministry's seasonal announcement for 2013 lists exactly that, direct cars from Osijek and from Vinkovci inside a Zagreb–Split working.

What happens at Zagreb at a quarter to one

The train is not one train for its whole length. The portion from Osijek runs west through Bjelovar; a second portion leaves Vukovar at the same minute, 18:44, and comes up through Vinkovci and Slavonski Brod on the main line. Both reach Zagreb Glavni kolodvor around midnight, the carriages from the two are joined into one train there, and at 00:46 it leaves for the coast. It is the same arrangement in reverse in the morning: out of Split at 21:37, divided at Zagreb after breakfast, and away to two different corners of Slavonia.

The first half of this journey is the half nobody photographs. Between Osijek and Zagreb the train crosses Podravina — the Drava country — on a railway that is single track, unelectrified and, for most of its length, laid out for a world of timber yards and sugar beet rather than holidaymakers. It is worth knowing what it is made of, because the six hours before Zagreb pass over four separate generations of railway building, and the newest of them opened in 2019.

Four railways, one night

From Osijek to Virovitica the train runs on the Podravska magistrala, the Varaždin–Dalj line: 250 kilometres end to end, opened in pieces as the money appeared — Osijek to Dalj in 1870, Virovitica to Slatina in 1885, Slatina to Osijek in 1895, and the Koprivnica end not until 1912. West of Virovitica, at Pitomača and Kloštar, the train is still on that alignment.

Then it turns south for Bjelovar, and this is the interesting part. The Bjelovar–Kloštar line opened in two bites, Bjelovar to Mišulinovac on 1 September 1899 and Mišulinovac through Kloštar to Virovitica on 4 May 1900, and it paid: in 1908 it carried 342,634 passengers and 125,759 tonnes of freight. Freight drifted away to the Koprivnica route after 1946, passenger trains stopped on 30 June 1968 for want of custom, and in 1980 the rails were lifted. It stayed a line on old maps for a decade and a half. Then it was rebuilt, at a cost of more than three million German marks, and trains ran again from 5 October 1995 — a railway taken up and put back within one working lifetime.

The last stretch into Zagreb uses something newer still. Between Gradec and Sveti Ivan Žabno there are 12.2 kilometres of railway that did not exist when this century began: a single unelectrified track laid for 120 km/h, built by a Spanish and German joint venture for €34.4 million of European regional and cohesion money, with three new stations at Lubena, Remetinec Križevački and Hagnje. Work started in December 2015 and it went into service on 15 December 2019. It is the newest piece of railway the train touches, and it is what lets a Bjelovar train reach Zagreb without going the long way round by Križevci.

A locomotive built where the journey starts

The engine on the front for much of this run is an HŽ class 2044 — originally JŽ series 645, an EMD GT22HW-2 built under General Motors licence by Đuro Đaković at Slavonski Brod, in Slavonia, in the early 1980s. It is 1,845 kW, good for 124 km/h, and HŽPP now uses the class on passenger work only, on the Koprivnica–Osijek line and on Ogulin–Knin–Split. That is both halves of this journey, worked by a machine built in the same province the train sets off from.

Croatian enginemen gave the class two names. One is Džems — James. The other is Mala karavela, the little caravel, which is a strange thing to call a locomotive until you have watched one bring a train down to the Adriatic at seven in the morning.

The night, and what you sleep in

South of Zagreb the train is on the Lika railway, the line over the karst to Dalmatia that took twelve years to build and was finished in 1925, and it climbs away from Karlovac while most of the train is asleep. HŽPP runs both sleeping cars and ordinary seated carriages on it. A berth is charged on top of the ticket and the price depends on how much of the compartment is yours: €9 in a three-berth, €13 in a two-berth, €25 to have it to yourself. The sleepers are the operator's own WLee cars — a narrow compartment, grey and blue, and a bed made up along the window wall.

The wake-up is worth staying up for in the other direction. Southbound the train is at Gračac at 05:19 with eleven minutes to stand, at Knin at 06:34 under the Dinara, and then it works down through Drniš and Perković at 07:31 into the country of stone walls and scrub oak. The last half hour is the good one: down to the water at Kaštel Stari at 08:17, then along the northern shore of the Kaštela bay with Split across the water and the islands beyond it, into the terminus at 08:49.

Every time below is read from HŽPP's own GTFS timetable feed, downloaded on 16 August 2026, and checked against the operator's published seaside-trains page and its live traffic notices of the same week. The timetable period runs from 14 December 2025 to 12 December 2026; the third set of amendments came into force on 14 June 2026.

The season is nine weeks. Southbound, train 1880 runs daily from Saturday 27 June to Friday 28 August 2026. Northbound, train 1881 runs daily from Sunday 28 June to Saturday 29 August 2026. Outside those dates neither train exists.

Osijek to Split — train 1880

Fourteen hours and five minutes, twenty-three stops. The stand at Zagreb Glavni kolodvor is twenty-six minutes, 00:20 to 00:46, and it is not idle time — that is where the train is put together.

Split to Osijek — train 1881

Fourteen hours and thirty-eight minutes. The northbound stand at Zagreb is longer — fifty-two minutes, 05:47 to 06:39 — because the train is being taken apart rather than assembled, and because the Slavonian legs then run in daylight.

The other half of the same train — Vukovar

A second portion works the eastern Slavonian main line through Vinkovci and Slavonski Brod, and joins the Osijek carriages at Zagreb.

748 is the Sunday arrangement and it is a different shape: it leaves Vukovar nearly five hours earlier at 16:37, is into Zagreb at 21:53, and its carriages then wait almost three hours for the night train to be made up.

Northbound, the Vukovar carriages leave Split with the rest at 21:37 and run on from Zagreb as train 741 — away at 06:04, Slavonski Brod 09:40, Vinkovci 10:29, Vukovar 10:49.

Outside the nine weeks

The journey remains possible with a change at Zagreb, though not in one day. Train 780 leaves Osijek at 16:18 and reaches Zagreb at 22:10, daily, all year; train 523 leaves Zagreb at 13:49 the following afternoon and is in Split at 21:47, also daily and all year. Coming the other way, 781 runs Zagreb 06:39 to Osijek 12:16 every day of the year — the same path the night train's Slavonian leg uses in the morning.

Engineering work in August 2026

The Osijek–Bizovac section, the first half-hour out of Osijek, is closed for track renewal on weekdays from 3 to 31 August 2026 — Monday to Thursday from 05:50 to 14:50, Fridays to 14:30, with 5 August and weekends excepted. Buses replace trains between Bizovac and Osijek in those hours. The operator's published list of substituted services names four trains — 6011, 6071, 6073 and the daytime 983 — and the night trains are not on it. The notices board is edited most weeks and is worth a look on the morning of travel.

This is an ordinary domestic ticket on Croatia's national operator, with no premium for the fact that it runs overnight — but a small stack of extras on top, all published. A reservation is compulsory at €1.06, and it applies to everyone, including the passengers HŽPP carries free on a smart card. A sleeping-car berth is charged separately: €9 in a three-berth compartment, €13 in a two-berth, €25 for sole occupancy. Seated carriages run in the same train for anyone who would rather not.

Two discounts both apply here. The seaside offer takes 40 per cent off fares to the coast and this train is named on the page that carries it; separately, buying online rather than at a window is 10 per cent cheaper. The operator publishes no fixed route fare, because it depends which reductions the passenger qualifies for.

This train is covered by Interrail and Eurail passes. Interrail's own Croatia page lists the country's domestic night trains among the services a pass is valid on, and names the summer Split–Zagreb–Osijek working specifically, alongside the daytime InterCity routes from Zagreb to Split, Rijeka and Osijek.

What the pass does not cover

Two things are charged on top, and between them they are most of what this journey costs beyond the fare:

• The reservation. Interrail lists reservations as required on Croatia's night trains, and HŽPP charges €1.06 for one. There is no way to travel on this train without it.
• The berth. A place in a sleeping car is a separate charge of €9, €13 or €25 depending on how many share the compartment. A pass covers the journey, not the bed.

Whether it is worth buying one for this

For this journey alone, no. The cheapest Interrail Croatia Pass is €67 for an adult — three travel days within a month, second class — or €50 for a traveller aged 12 to 27, read from Interrail's own checkout in August 2026. HŽPP's ordinary fares to the coast are already discounted by 40 per cent in season, with a further 10 per cent off for booking online. A single crossing of the country, even with a berth, does not come close to the price of the cheapest pass.

The arithmetic changes if Croatia is a fortnight rather than a night. The country is long and its railways are slow, which is exactly the shape a country pass suits: Osijek to Split overnight, a few days on the coast, back up to Zagreb on the Lika line, over Gorski kotar to Rijeka, and out to Istria — that is four long journeys, and a pass covering all of them stops the fares mounting up. The Croatia Pass also carries a 20 per cent discount on the Split–Ancona ferry, which is useful if the Adriatic is a stepping stone to Italy rather than the destination.

One practical note

Because the reservation is compulsory and the train is a seasonal one with a fixed number of berths, a pass does not remove the need to book the specific night in advance through the operator. Pass holders reserve the same way everyone else does, and in high summer the sleeping cars on a train that only runs for nine weeks are the part that goes first.

Most of what this train passes in Slavonia, it passes in the dark. That is an argument for breaking the journey rather than for skipping it: the same rails carry daytime trains, and the towns strung along the Podravina line — Našice, Slatina, Virovitica, Bjelovar — are places almost no visitor to Croatia sees, with baroque castles, a Habsburg garrison grid and a mountain nature park among them.

The stops below run in the order the southbound train reaches them, from the Drava to the Adriatic. Two of them, Kopački rit and Papuk, are reached from stations on the line rather than from the platform itself, and both repay a day. The last is the one the train delivers at breakfast: the bay of Kaštela, seven villages and their fortresses on the waterline, which the train runs along for its final half hour before it stops at Split.

A night train removes the need for one hotel and creates the need for two others — somewhere in Osijek before an evening departure, and somewhere in Split for the day the train delivers you into. Both ends are well served, and the Slavonian end is the cheaper and the quieter of the two.

Osijek repays an extra night at the start. The train leaves at 18:44, which means a whole day in the city is available to anyone who arrives the day before: Tvrđa in the morning, the Drava promenade and the suspension bridge over to Baranja in the afternoon, and dinner before the walk to the station. Both the hotels below are in the centre, within easy reach of it.

At the other end, the train is into Split at 08:49, which is several hours before any hotel will hand over a room. The practical answer is a hotel that will hold luggage from breakfast time — worth asking when booking — leaving the morning free for the palace and the Riva while the room is made up.

The cards below carry no prices, star counts or ratings. Each description says only what that hotel states about itself on its own website, and every link was opened and read before it was published.
