The Sofia–Istanbul Express — Bulgaria to Türkiye by Night Train

There is still a train from Bulgaria to Türkiye, and it still leaves in the evening. Sofia Central Station at a quarter to seven is not a romantic place — a concrete concourse of the 1970s, a departure board, a red locomotive somewhere down the platform — but coupled behind it are a Turkish sleeping car and a couchette car, and in the morning they will be in Istanbul.

That is the whole proposition, and it is a good one. The Sofia–Istanbul Express runs daily, takes about fifteen hours, and costs less than dinner for two. It carries no seats at all: everyone aboard has a berth, because everyone aboard is going to be on it all night. Somewhere around midnight it stops at the Bulgarian frontier, and an hour later it stops again on the Turkish side, and the whole train gets out onto a floodlit platform with passports in hand while a Bulgarian electric locomotive is exchanged for a Turkish one. By the time it is light you are crossing Thrace, and by mid-morning it is over.

The one thing to know before you book

The train is named for Istanbul and does not reach it. It terminates at Halkalı, a suburban station out in the district of Küçükçekmece, 27.63 kilometres west of Sirkeci Terminal. This is not a temporary arrangement and it is not the railway being difficult. Sirkeci — the station where the Orient Express set down its passengers from 1883, the one with the arched windows and the clock — took its last mainline train in 2013. It is now a stop on the Marmaray, the commuter line that runs under the Bosphorus, and there is simply nowhere left in central Istanbul for a sleeping car to arrive.

So the journey has an epilogue. You get off at Halkalı, walk along the platform to where the Marmaray trains wait, and ride the last stretch into the city on a commuter service, under the water, alongside people going to work. It sets you down at Sirkeci. You arrive at the Orient Express's terminus after all — just not on the Orient Express's train, and about a century late.

Whether that reads as a disappointment or as the most interesting thing about the trip is genuinely a matter of temperament. It is, at any rate, what happens, and it is better known beforehand than discovered at half past nine in the morning with a suitcase.

The train that leaves Sofia is a short one — a Turkish sleeping car, a Turkish couchette car, and whatever else is running that night — behind a BDŽ class 44 electric. For the first three hours it is simply a Bulgarian express on the main line east, and a good one: out through the suburbs, then along the Maritsa valley with the Rhodope foothills dark on the right.

Plovdiv comes up in the late evening, and it is the one stop where a real number of people join. It is worth knowing that BDŽ sells a Plovdiv–Halkalı ticket as well as the through one, because picking the train up here removes three hours of darkness from the trip and buys you a day in the oldest city on the route. After Plovdiv the train works its way down through Dimitrovgrad and into the flat, hot corner where three countries nearly meet.

The border, which takes about two and a half hours

Around midnight the train reaches Svilengrad, the last Bulgarian station, and stops for the best part of an hour. Out of the window on the Maritsa side, though you will not see it in the dark, is a 295-metre Ottoman bridge of 1529 — the first major commission of Mimar Sinan, whose masterpiece the train will pass two stops later.

Then a few kilometres of no-man's-land, and Kapıkule, where the real business happens. The train stands here for something over an hour and a half. Everyone gets down onto the platform and queues at the passport windows; the Bulgarian locomotive comes off and a TCDD machine goes on. This is the part of the journey people describe afterwards. It is one in the morning, the platform is lit like a filling station, and a couple of hundred people from a dozen countries are shuffling forward in dressing gowns and coats over pyjamas. It is not efficient and it is not comfortable, and it is the most border most travellers ever actually stand in.

Thrace, at dawn

Edirne follows in the small hours — the Ottoman capital before Constantinople fell, and the site of the Selimiye Mosque, which Sinan finished in 1575 and thought his best building. In the dark you will see very little of it, which is an argument for spending a day there on the way back.

What you do get is the morning. The train runs the long, straight miles across Thrace as it gets light: wheat and sunflowers, small towns, level crossings, the occasional stork's nest on a pole. It calls at Çerkezköy, and then the country gradually stops being agricultural and starts being Istanbul — warehouses, apartment blocks, motorway junctions, the sprawl going on for the better part of an hour before the train finally comes to a stand at Halkalı.

What the train is like

Plainly: it is an old train, and a functional one. Sleeping compartments come as singles and doubles; couchettes are sold four or six to a compartment. There is air conditioning, there are luggage racks and power sockets, and there is no restaurant car and no buffet — nothing to eat or drink is sold on board, so whatever you want overnight is bought at Sofia or Plovdiv first. The coaches carry a good deal of graffiti on the outside. None of this is a secret and none of it spoils the trip; it is a working overnight service between two capitals, priced accordingly, and it does exactly what it says.

The Sofia–Istanbul Express is a daily service in both directions, run jointly by Bulgarian State Railways (BDŽ) and TCDD Taşımacılık. Times below are from BDŽ's own published timetable for this route and from the matching timetable published by TCDD, as of August 2026.

Southbound — Sofia to Istanbul (trains 493/12504)

Journey time is about 15 hours.

Northbound — Istanbul to Sofia (trains 12503/492)

Journey time is about 15 hours.

Why only the endpoints are given as clock times

The departure and arrival times above are identical in three separate sources — BDŽ's timetable, TCDD's timetable and BDŽ's live journey planner, which shows train IC-INT 493 leaving Sofia at 18:50 and reaching Svilengrad at 00:05. The intermediate stops are a different matter: the two railways' own leaflets disagree with each other by a few minutes at Plovdiv, Dimitrovgrad and Svilengrad, so those are described here rather than quoted to the minute. The station departure boards on the night are the ones to go by.

The season, and what is not yet published

Both operators publish this timetable as a dated block: BDŽ's runs 12 June to 12 October 2026, TCDD's 11 June to 10 October 2026. BDŽ describes the service simply as a daily train and attaches no seasonal condition to it, and the train has been photographed running outside a June–October block in previous years — so this looks like a timetable period rather than a summer season. Even so, times for dates after 12 October 2026 had not been published when this page was checked, and tickets only go on sale two months ahead.

One live caution

BDŽ has posted a standing notice that repair work at the Plovdiv railway junction will change the routes and times of the international trains to and from Halkalı, and that advance ticket sales are limited until the scope and dates are settled. Anyone booking this train more than a few weeks out is booking against a timetable the operator has said may move.

Tickets are cheap and the reservation is not optional. Because the train carries no seated accommodation, every passenger holds both a ticket and a berth reservation, priced separately: the fare is €26.40 second class and €39.60 first, with children 7–12 at half, and the reservation €10.00 in a four-berth couchette or €15.00 for a berth in a two-bed sleeper. So a second-class ticket with a couchette is about €36 all in — for fifteen hours and a bed between two capitals, among the best value in European railway travel.

A one-way ticket is valid fifteen days and a return a month, so the journey can be broken. Tickets go on sale two months ahead at BDŽ's international offices, though the operator warns that repair work at the Plovdiv junction is limiting the advance window. Tariff as of August 2026.

Both countries this train runs through are in the Interrail and Eurail networks — Bulgaria via BDŽ, and Türkiye via TCDD, which has its own one-country pass — so a Global Pass covers the track under you for the whole journey.

That is not the same as the trip being free, and for most people a pass is not worth buying for this journey.

Why not

The reservation is compulsory and a pass does not include it. Pass holders pay exactly the same berth fee as everybody else: €9.40 in a six-berth couchette, €10.00 in a four-berth, €15.00 for a berth in a two-bed sleeper, €35.00 for sole use of a single. That is the larger part of what a normal passenger pays anyway.

The arithmetic is unforgiving. A full second-class ticket from Sofia to Halkalı is €26.40. A pass saves you that €26.40 and nothing else, while the berth — €10 to €35 — still has to be paid. No Interrail or Eurail pass costs anything like €26.40 for the days it would use up here.

When a pass does make sense

If you are already carrying a Global Pass for a longer trip and this train is one leg of it, then use it: turn up at a BDŽ international ticket office, buy the berth reservation on its own, and you are done. The pass has earned its keep elsewhere and this leg rides on it for the price of the berth.

What does not work is buying a pass for this journey. At these fares, the ordinary ticket is the cheaper answer, and it is the one to buy.

A practical note either way

Whether you travel on a pass or on a ticket, the reservation has to be made in advance — the train has no seats to fall back on, so there is no such thing as boarding it and sorting the paperwork out later. Reservations open two months ahead.

This is a night train, which means most of the route passes in the dark. The places worth stopping for are therefore best treated as reasons to break the journey rather than as things to watch from the window — and the ticket helps, since a one-way fare stays valid for fifteen days.

Two stops repay a day each. Plovdiv, three hours out of Sofia, is one of the oldest continuously inhabited cities in Europe and has both a working Roman theatre and a hill quarter of painted Revival houses. Edirne, the first Turkish stop, was the Ottoman capital for most of a century before Constantinople fell, and holds the building its architect considered his best.

There is also a thread running the length of the line that is easy to miss in the dark. Mimar Sinan, the greatest of Ottoman architects, is present at three points on this route: the mosque by Sofia station, completed in 1566; the bridge at Svilengrad, his first major work, of 1529; and the Selimiye at Edirne, finished in 1575 when he was around eighty. The train passes all three in a single night, in the wrong order, mostly asleep.

The train itself is one night's accommodation, which is a large part of its appeal — but it leaves Sofia in the evening and arrives in Istanbul mid-morning, so a bed is wanted at both ends, and the fifteen-day ticket makes a stop in the middle worth considering.

At the Sofia end, staying central rather than beside the station is the better plan: the city's sights are clustered around Vitosha Boulevard and the cathedral, and the station is a short taxi or metro ride from any of them. In Istanbul the opposite is true — the Marmaray sets you down at Sirkeci, right on the edge of the historic peninsula, so a hotel within walking distance of that station puts you at Hagia Sophia and Topkapı on foot.

Plovdiv is the stop that rewards a night of its own. Joining the sleeper there rather than at Sofia cuts three hours of darkness off the journey, and the Old Town on the hill is close enough to the station to walk.
