To Istanbul by train...
One train per day links Europe with Istanbul, a sleeper train called the Sofia-Istanbul Express. This runs from Sofia to Istanbul every day all year with sleeping-cars & couchettes. From June until October it conveys a direct couchette car from Bucharest to Istanbul, at other times of year you travel from Bucharest to Dimitrovgrad in Bulgaria on a series of connecting trains where you join the sleepers or couchettes of the Sofia-Istanbul Express to Istanbul. This page explains train times, fares & how to buy tickets.

* = Transfer between Halkali & Istanbul Sirkeci by frequent Marmaray suburban train as shown here.

How to read this timetable
You read downwards, each column is a separate train. Each train runs every day.
There's a summer & winter service, remember that Bulgaria & Romania put their clocks forward April-October, but Turkey remains on GMT+3 all year.
Sofia<>Istanbul is a direct train every day all year with sleeping-cars & couchettes (no seats).
Bucharest<>Istanbul is a series of connecting trains in winter, connecting into the Sofia-Istanbul train at Dimitrovgrad. But in summer there's a direct couchette car between Bucharest & Istanbul with no need to change, as follows:
Direct couchette car from Bucharest to Istanbul every day from early June to early October, attached to trains 461, 465 & 493/12501.
Direct couchette car from Istanbul to Bucharest every day from early June to early October, attached to trains 12502/492, 464 & 462.
When there's no direct couchette car, you travel between Bucharest & Istanbul using seats cars between Bucharest & Dimitrovgrad on each of the trains shown above, then the sleepers or couchettes of the Sofia-Istanbul Express between Dimitrovgrad & Istanbul. Don't worry, it normally all works like clockwork.
Times may vary! How to check this timetable: You can find an accurate timetable in .pdf format at the Bulgarian Railways website www.bdz.bg/en/a/sofia-istanbul-sofia which is what I use to update this page (please let me know if that link stops working). Don't expect timetables to be posted months in advance, for example expect the June-September .pdf timetable to be posted on their website in late May or even early June, and so on. You can try checking times at the German Railways website int.bahn.de, but bear in mind that both Bahn.de and the Interrail/Eurail Railplanner app may have incomplete or even incorrect data for this route, for example there is no change of train at Kapikule or at Plovdiv. The train runs direct from Sofia to Halkali via Plovdiv & Dimitrovgrad, exactly as I show above.

What's the train like?
Sofia-Istanbul sleeping-cars
The Sofia-Istanbul Express has two Turkish TVS2000 sleeping-cars built in 1998 (car numbers 483 & 484) and can have a 3rd such car at busy times. The car number is indicated on the steel destination plate attached to the side of the car towards one end.
Each sleeping-car is air-conditioned with 10 compartments. Each compartment can be sold as a double (2nd class fare or railpass plus the double sleeper supplement) or single (1st class fare or railpass plus the single sleeper supplement).
Each compartment has an upper & lower berth, sink, table & fridge. All necessary bedding is provided, along with soap and towel. Berths fold away to reveal two armchairs for day use. There are toilets at each end of the car. There's a 2-pin power outlet intended for electric razors, but no power outlet specifically for mobiles & laptops. These cars were built with a shower compartment at one end, but this is now used as a storeroom for bedding. You may be able to buy tea or coffee from the sleeper attendant.
Sofia-Istanbul & Bucharest-Istanbul couchette cars
In addition to the sleeping-cars, the Sofia-Istanbul Express has one Turkish TVS2000 air-conditioned couchette car built in 1996 or 2002 (car number 485). The direct summer-only couchette car between Bucharest & Istanbul is of the same type (car 479). The car number is indicated on the steel destination plate attached to the side of the car towards one end. The car has 10 compartments each with 4 berths, two upper & two lower. Sheets, pillow & blanket are provided, but you arrange these yourself. The beds fold away to form seats for day use as shown below. There are toilets at each end of the car. There's a 2-pin power outlet in each compartment above the door to the corridor, but you'll need a 2m cable to use it whilst sitting down with your phone or laptop.

What's the journey like?
Bucharest to Dimitrovgrad
Between June and October there's a direct couchette car from Bucharest to Istanbul. Outside this period, you travel from Bucharest to Dimitrovgrad on a series of connecting trains, but it all works like clockwork and you won't be the only person making these connections. The route & scenery are the same.
The train is shown on the departure boards at Bucharest Gara de Nord as going to Ruse. A few hours after leaving the imposing Gara de Nord, the train reaches the Romanian border point, Giurgiu Nord. It then crosses the Danube into Bulgaria on a 2.5 km long steel bridge, the longest steel bridge in Europe, built in 1954 and now fitted with a road deck above the railway. It curves around off the bridge and arrives at Ruse, the Bulgarian border station on the other side.
When the Bucharest-Istanbul couchette car operates, it's attached to a direct Bucharest-Sofia train from Bucharest as far as Gorna Orjahovitsa - that Bucharest-Sofia train in fact runs for some weeks before and after this period, with no need to change at Ruse. However, in the winter timetable, you take an air-conditioned Romanian express railcar from Bucharest to Ruse and change into a Bulgarian locomotive-hauled train bound for Sofia, taking it as far as Gorna.
The train then spends a lazy afternoon meandering along pleasant river valleys across rural Bulgaria, have your camera handy. Pour yourself a beer or glass of wine (remember to bring your own food & drink), read away the hours & enjoy the trip. The highlight is the journey through the lush green Shipka Pass. The train from Gorna to Dimitrovgrad calls at Veliko Tarnovo, the ancient capital of Bulgaria - well worth a 24h stopover!
Sofia to Dimitrovgrad
The Sofia-Istanbul Express leaves Sofia's impressive communist-era central station and heads off across Bulgaria as night falls. Remember to bring your own food & drink, maybe even a bottle of wine, as there's no catering on board.
Dimitrovgrad to the Turkish border
At Dimitrovgrad, the Bucharest-Istanbul couchette car (when running) is attached to the Sofia-Istanbul Express. When it's not running, passengers from Bucharest & Veliko Tarnovo change onto the sleepers & couchettes of the Sofia-Istanbul Express.
Border controls at Svilengrad, Bulgaria
Late at night, the train reaches the Bulgarian border point at Svilengrad. You remain on the train, Bulgarian border guards come on board. They collect all passports and take them off the train to check them, they come back on board and return them before the train leaves. This happens in both directions, eastbound & westbound.
When Bulgarian controls and completed and passports returned, the train heads across the border into Turkey, reaching the Turkish border station of Kapikule well after midnight.
Border controls at Kapikule, Turkey
At Kapikule you need to leave the train for border formalities, in both directions:
Eastbound procedure: Step off the train onto the platform, taking all your bags with you. Step 1, go to the passport office further along the platform in the main building and get your passport stamped (see the photo below). Step 2, get your bags X-rayed in the small white shed-like building on the platform to the left of the main station building. After the train itself has been security checked, you can then re-board. Note that until 2022 you had to do the X-ray check first and passport check second, but in 2022 it was reportedly switched round. Feedback appreciated.
Tip: You may find the station cafe open for the train arrival, it accepts contactless payment cards so enjoy a late night coffee or snack while you wait to reboard!
Westbound procedure: Step off the train onto the platform, in this direction you can leave your bags on the train. Go to the passport office on the platform in the main building, get your passport stamped (see the photo below). You can then re-board the train.
Remember that time zones change here: From the last Sunday in March to the last Sunday in October, Bulgarian & Turkish time is the same, GMT+3. But Turkey has no Daylight Saving Time, so Turkish time is 1 hour ahead of Bulgarian time in winter.
The train arrives at Kapikule on the platform shown above, adjacent to the station building. X = X-ray baggage check shed. P = passport office in main building. Photo courtesy of Daniel Sterk.
Onwards to Halkali & Istanbul
In years gone by, the train used to make a dramatic entry into Istanbul through the Byzantine Walls of Theodosius, skirting the Sea of Marmara underneath the very walls of the Topkapi Palace into the beautiful Istanbul Sirkeci station, opened in 1888 in the heart of the city. However, the train now terminates at a suburban station called Halkali some 25km west of Sirkeci, expect an arrival an hour or two late, so allow for this and enjoy the ride. You then take one of the frequent Marmaray suburban trains into Istanbul Sirkeci as explained further down this page. Sirkeci station is walking distance from all the sights, or you can hop into a taxi to the famous Pera Palas Hotel. Map of Istanbul showing Sirkeci station.
Travel tips
-
Is the overnight train safe?
Yes. In a sleeper or couchette it's comfortable and safe for families, solo females, anyone.
-
Finding & boarding your train
As with virtually all European trains, there's no check-in. Just stroll into the station, find your train and get on, any time before it leaves. The sleeper or couchette attendant will normally greet you on the platform at the door to the sleeping-car and check your reservation. He'll come round and see you soon after departure to take your ticket or pass.
In Bucharest, the train is shown on the departure boards as going to Ruse. In winter train it's train 1095, in summer train IRN 461.
-
Luggage
You take your luggage with you into your sleeper or couchette compartment and simply stick it on the luggage racks above the window, over the door to the corridor, or on the floor. Nobody weighs it, measures it, or worries about how much you take. More about luggage on European trains.
-
Power outlets & WiFi
In the sleeping-cars, there's a shaver socket in each compartment near the sink aimed at electric razors, but none specifically for laptops or mobiles. In each couchette compartment there's a 2-pin socket above the door to the corridor also aimed at electric razors, you'll need a 2m cable if you want to sit down with your laptop or mobile whilst using it. You may wish to bring a battery pack to keep your phone charged. There's no WiFi, but there is mobile data reception along the route except in rural areas.
-
Bring your own food & drink
There's no catering car, so take your own food & drink, even a bottle of wine if you like. The sleeper attendant may be able to sell you tea or coffee.
-
Scenery
The scenery through Bulgaria on the route to or from Bucharest is superb, snaking through Bulgarian river valleys and up (or down) the Shipka Pass.
-
Be ready for border control
You need to get off the train briefly for border control at Kapikule on the Turkish border, read the border control information in the What's the journey like? section above to understand the procedure on both Bulgarian & Turkish side of the border. If you know the procedure and are first off the train at Kapikule when it stops, you can be back in bed before everyone else!
-
Carry small denomination Turkish banknotes for the Marmaray local train into Istanbul
Buying a ticket for the Marmaray local trains from Halkali into Istanbul is an initiative test, as the section below explains. Try to get hold of some small-denomination 10 & 20 lira banknotes so you can buy a ticket using the machines.
-
X-ray bag check at when leaving Halkali: There's now a brief baggage X-ray check when accessing the westbound train to Sofia/Bucharest at Halkali, similar to the ones the Turkish Railways do for their YHT high-speed trains.
-
Using an Interrail or Eurail pass
You can use this train with a pass, of course, paying the relevant couchette or sleeper supplement. However, there's a minor irritation when using a pass from Sofia, Bucharest or Dimitrovgrad to Istanbul. You are of course using a direct overnight train so the Interrail night train rule applies and only one pass day (the date of departure) is used. Unfortunately, the Railplanner app incorrectly thinks it's a separate train from Kapikule to Istanbul, therefore if you add it to your pass directly from the Railplanner timetable it will trigger the use of a second pass day to cover what it thinks is a second train leaving after midnight. The solution is to add the Bucharest or Dimitrovgrad to Istanbul train to your pass manually.
How to transfer from Halkali to Sirkeci
-
The international train from Sofia & Bucharest to Istanbul now terminates at Halkali, a suburban station 25 km west of Istanbul's famous Sirkeci station, the original terminus in the city centre opened in 1888.
-
The easiest way to reach Sirkeci is to take a frequent Marmaray suburban train, these run at least every 15 minutes, journey time from Halkali to Sirkeci around 35 minutes, fare around TL 35 (€1.90).
Use the self-service machines at the station to buy an Istanbulkart public transport smartcard for 50 TL, then top it up to get to Sirkeci.
As of December 2022 there is (finally!) a self-service ticket machine at Halkali which accepts contactless bank cards. Previously there were only machines which took Turkish lira in cash, in small-denomination 10, 20, 50 lira notes.
From 2023 there's an even easier option, you can simply tap in & out with any contactless credit card, no need to buy a ticket at all. You're charged a higher fare, but it's still cheap.
-
The Marmaray trains arrive at the new underground platforms beneath the historic (but now trainless) ground level terminus. They continue beyond Sirkeci through the Bosphorus rail tunnel to Söğütlüçeşme station on the Asian side, where the high-speed YHT trains to Ankara & Konya start,
-
If you prefer to go direct to your hotel by taxi, it will cost the equivalent of around €16 from Halkali to central Istanbul, but have Turkish lira with you to pay the driver as there is no ATM at Halkali.
How to transfer from Sirkeci to Halkali
-
The international train to Sofia & Bucharest now leaves from Halkali, a suburban station 25 km west of Istanbul Sirkeci station in the city centre.
-
The easiest way to reach Halkali from central Istanbul is to take a frequent Marmaray suburban train from Sirkeci station, these run at least every 15 minutes, journey time from Sirkeci to Halkali around 35 minutes, fare around TL 35 (€1.90).
From 2023 you can simply tap in & out with any contactless credit card, so no need to buy a ticket at all. You pay a little more than the usual fare, but it's the easiest option unless you already have an Istanbulkart.
The Marmaray trains leave from the underground platforms at Sirkeci, beneath the now-trainless ground level terminus.
To be on the safe side, I'd leave Sirkeci at least 1h15 before the sleeper is due to leave Halkali. Check the departure time from Halkali shown on your ticket carefully, as it varies.
At Halkali there's now a brief baggage X-ray check when accessing the platform for the train to Sofia & Bucharest.
Tip: Buy food and drink before you leave as there are few or no facilities n or around Halkali station, just a waiting room.
-
If you prefer to go from your hotel to Halkali by taxi, it will cost the equivalent of around €16.
