Circum-Baikal Railway

Every great railway has a stretch that cost more than the rest. On the Trans-Siberian it was the last ninety-odd kilometres, along the southern shore of Lake Baikal, where the mountains come down into the deepest lake on earth and leave no room for a train. Engineers called the finished line the Golden Buckle of the Steel Belt of Russia — a buckle because it joined the two halves of a Trans-Siberian that Baikal had kept apart, and golden because of what it cost. A kilometre of main line between Chelyabinsk and Vladivostok came to about 93,000 roubles. A kilometre here came to roughly 130,000.

What they bought was a shelf blasted along the base of a cliff, and the densest concentration of railway engineering in Russia: 39 tunnels, seventeen free-standing galleries, some 280 retaining walls and around 470 bridges, viaducts and culverts, which works out at roughly one structure every hundred metres. Then, half a century later, the railway walked away from it. A new line was cut over the Olkha plateau and opened on 1 January 1949, and in 1956 the old approach from Irkutsk was lifted and drowned under the reservoir of a new hydroelectric dam. The Golden Buckle was left attached at one end only.

That is what makes it worth the day. This is the piece of the Trans-Siberian that the Trans-Siberian abandoned, and it is still open — not as a preserved museum line but as an ordinary local railway, with a handful of trains a week, tickets at the regional tariff, and villages along it that have no road. You board at Slyudyanka, on the working main line, and four and a half hours later you stop at a buffer beam at Port Baikal, facing the water that swallowed the rest.

The train leaves Slyudyanka I and, for a few minutes, behaves like part of the main line — climbing away west with the Trans-Siberian's wires overhead and freight standing in the loops. Then the wires stop. From Kultuk onward nothing is electrified, and everything that runs here runs behind a diesel; the excursion sets are electric units towed with their pantographs folded, which is a small absurdity you will notice in every photograph of this railway.

From Kultuk the line drops to the water and turns north-west, and the character never changes again. On the right there is rock; on the left there is Baikal, close enough that in calm weather the carriage windows catch the reflection of the cliff. Speed settles to 20–25 km/h. The stopping places are not villages so much as kilometre posts with names — 149 km Staraya Angasolka, 129 km Baklan, 123 km Kirkirey, 120 km Rechka Marituyka, 110 km Polovinnaya, 107 km Ponomaryovka, 102 km Shumikha, 98 km Khvoynaya — and the numbers count down towards Port Baikal because they are the original mileage of a main line that no longer exists.

The engineering, seen from the window

The tunnels come in bursts. There are 39 of them along 8,994 metres of bore, and the longest, Polovinny, runs 778 metres straight through a headland at the midpoint of the line. Where the cliff was too loose to tunnel and too steep to cut, the builders roofed the track instead: stone galleries open on the lake side, so that the train runs through a colonnade with the water flashing between the piers. Between them are the viaducts — steel spans on masonry arches, most of them over streams that arrive off the mountain in a few violent weeks each spring.

It is worth knowing what you are looking at. Almost all of it is original, because the line was double-tracked as a main route and then, when the traffic left, one road was lifted and taken away for use elsewhere. The wide, grassy formation beside the single running line at places like Marituy is not neglect. It is the space where the other track used to be.

What the ride is actually like

Slow, and not luxurious. The ordinary services are suburban trains — bench seats, no catering, no electrical sockets — and they exist to serve people who live along a shore with no road. The excursion trains that run from Irkutsk are a different proposition: first and second class saloons, a guide on the public address, monitors showing the driver's-eye view, and stops long enough to walk to a portal and back. Both take the same line at the same speed past the same cliffs.

The last stretch runs out onto the flat at the mouth of the Angara, and the line ends. Port Baikal is a village of wooden houses, a locomotive on a plinth, and rails running down to a quay where the train ferries once loaded. Across the water, twenty minutes by boat, is Listvyanka. There is no way onward by rail, and that is the point of the place.

Two named local trains work the line, both run by the Baikal Suburban Passenger Company (BPPK): the Nerpochka ("little seal", trains 6801/6802) and the Baikal Wind (Baikalsky Veter, trains 6201–6204). Between them they give one or two round trips a day — and nothing at all on Wednesdays, when the line closes.

All times are Irkutsk time (MSK+5), as of September 2026.

Port Baikal → Slyudyanka I

The Nerpochka is the useful one: out in the morning, back in the afternoon, and it runs six days a week. Doing the line as a day trip on the Baikal Wind is not really possible in one direction — the return working leaves Port Baikal at 03:08 — so the westbound Baikal Wind is for people staying the night at the far end, at Port Baikal or at one of the trackside bases at Sharyzhalgay, Khvoynaya and Shumikha, all of which need booking in advance.

The line is open for independent travel all year, and the operator says so explicitly; winter services run to the same pattern. Excursion trains from Irkutsk keep their own calendar and are sold separately — see Tickets.

⚠️ Check before you travel. These are lightly used rural services and the pattern is revised seasonally. The live board is on the operator's own site: irkppk.ru (opens in a new tab).

There are two ways to ride, and they cost very different amounts. The local trains charge the ordinary suburban fare, set by the Irkutsk Oblast tariff service rather than by the railway, and revised each January; tickets are sold in the RZD Passengers app, at self-service terminals and at suburban booking offices across Irkutsk Oblast and Buryatia. There is no reservation and no allocated seat.

The alternative is a guided excursion train from Irkutsk, sold by the line's named tour operator, which includes commentary, walking stops at the tunnels and the boat back across the Angara. It runs year-round — an electric set in summer, a railbus in winter and late autumn — and costs from ₽7,500 for the day.

⚠️ The railway crosses Pribaikalsky National Park, and a permit is required to be there. Tour prices normally include it; if you travel independently, arrange it yourself before you go.

No rail pass covers this line, and none is worth buying for it. Interrail and Eurail do not extend to Russia at all, so the European passes are simply not in play.

Nor would a pass help if one existed. The Circum-Baikal is worked as an ordinary suburban service at a regionally regulated tariff — the cheapest kind of ticket Russian Railways sells, bought on the day in an app or at a window, with no reservation to make and no supplement to pay. There is no first-class option on the local trains to upgrade into.

The one thing worth pre-arranging is not a ticket at all. The line lies inside Pribaikalsky National Park, and visitors need a permit from the park authority; a guided excursion normally includes it, while independent travellers should obtain it before setting out.

The line is the attraction, and most of what there is to see stands beside the track: portals, galleries, viaducts and the halts that serve villages with no road to them. The stops below run west to east in the order the kilometre posts count them, from Port Baikal at 72 km to Slyudyanka at the far end — which is the opposite of the way most people ride, so read them backwards if you are coming from Slyudyanka.

Two practical notes. The whole railway sits inside Pribaikalsky National Park, so a permit is needed to be here at all, and camping is confined to marked places. And the halts are halts: there is no shop at most of them, no shelter worth the name, and the next train may be a day away. Whatever you get off to see, work out first how you are getting back on.

Where you sleep depends on which end you finish at. Most people ride out from Irkutsk and come back the same night, in which case the city is the answer and there is plenty of it. If you take the afternoon Baikal Wind, though, you are committed to a night at the far end, because the return working leaves Port Baikal at 03:08.

At that end the natural base is Listvyanka, twenty minutes across the mouth of the Angara by boat from Port Baikal and the closest thing to a resort on this shore. The two hotels below are there, both on their own sites.

There is also lodging on the railway itself. The operator lists holiday bases at Sharyzhalgay (139 km), Khvoynaya (98 km, at Ulanovo), Shumikha and Port Baikal — the Sharyzhalgay one partly made up of old railway carriages parked by the water. All of them take advance bookings only, none has a website we can safely point you at, and none is reachable except by train or on foot. Arrange them through the tour operator or by telephone before you travel, and do not turn up hoping.
