TL;DR: A plain-language guide to the Baku Tbilisi Kars railway corridor, what it means for regional travel, and how to think about trains, cars, and future routes.
Overview
The Baku-Tbilisi-Kars railway is often mentioned as if it were one simple passenger route across the Caucasus into Turkey. In practice, it is more complicated. The railway was built to connect Azerbaijan, Georgia, and Turkey, but passenger services have not always matched the romance of the map.
As of June 2026, the important traveler update is that the Tbilisi-Baku passenger train has resumed, while the onward passenger leg to Kars is still not a normal through-service for visitors. Check current rail announcements before planning around it.
What the Railway Is
The Baku-Tbilisi-Kars, often shortened to BTK or BTAK, is an 826-kilometre rail corridor linking Azerbaijan, Georgia, and eastern Turkey. It matters economically because it moves freight between the Caspian, the South Caucasus, and Turkey without passing through Armenia.
What Travelers Can Actually Use
The useful 2026 development is the resumed overnight passenger train between Tbilisi and Baku. It creates a practical city-to-city link for tourists again. The Kars extension is a different question. Until regular passenger service is confirmed, do not sell yourself a dream itinerary that depends on boarding in Baku and waking up in Turkey.
Why This Matters for Itinerary Planning
The train can replace a long transfer between Georgia and Azerbaijan, but it does not replace local transport. You still need separate plans for Kakheti, Sheki, Gobustan, Lahic, Kars, Ani, or eastern Turkey. Think of rail as a spine, not the whole body of the trip.
Georgia Side
Tbilisi is the natural Georgian hub. From there, you can rent a car for Mtskheta, Kazbegi, Kakheti, Borjomi, or western Georgia, then return the car before taking the train. This avoids unnecessary border paperwork for routes where rail is easier.
Azerbaijan Side
Baku is the arrival point and the best base for Gobustan and Absheron. For Sheki, Lahic, Quba, or Khinaliq, you still need a bus, train, driver, or separate rental plan inside Azerbaijan. The direct Baku to Sheki road is about 358 kilometres and deserves careful pacing.
Turkey Side
Kars, Ani, Lake Cildir, and eastern Turkey are excellent travel goals, but they currently require a separate transport plan. Flights, buses, domestic trains, or a Turkey rental may be more realistic than waiting for a through passenger service.
Traveler Expectation Check
The railway is strategically important, but that does not automatically make it a scenic tourist product. Before planning around it, ask three questions: Is the passenger service operating on my date? Can I buy a ticket as a foreign traveler? Does the route actually stop where I need to be?
Best Use Case
Use the Tbilisi-Baku passenger service as a practical link between two capitals, then design road days on either side. This gives you the romance of rail without pretending the train solves every rural destination.
Comfort on the Overnight
Pack for interrupted sleep. Border checks, lighting, announcements, and document control can break the night into pieces. Keep valuables close, bring snacks and water, and avoid scheduling an expensive private tour immediately after arrival unless you know you sleep well on trains.
FSTA Route Support
FSTA can help travelers use the railway sensibly: car where roads add value, train where it simplifies the border, and local transport where a through-drive would create more paperwork than freedom.
