124-639: A number of branch lines have been built or are under construction. In January 2012 the Russian mining company Mechel completed the construction of the 320-kilometre-long branch line to Elginskoye, branching from the BAM station Ulak, west of the Zeya River crossing in northwestern Amur Oblast . The branch line connects the Elginskoye coal mine to the Russian railroad network. Currently under discussion

155-452: A very poor state, with collapsed bridges, dangerous river crossings, severe potholes and "unrelenting energy-sapping bogs". The narrow, dilapidated Vitim River Bridge (aka Kuandinsky Bridge) that crosses the Vitim river has attracted attention since its first appearance on social media in 2009. The passage of the bridge is forbidden since 2016 but remains a common road for individuals to reach

372-612: The Trans-Siberian Railway . The Soviet Union built the BAM as a strategic alternative route to the Trans–Siberian Railway, seen as vulnerable especially along the sections close to the border with China . The BAM cost $ 14 billion, and it was built with special, durable tracks since much of it ran over permafrost . Due to the severe terrain, weather, length and cost, Soviet general secretary Leonid Brezhnev described BAM in 1974 as "the construction project of

403-457: The 19-kilometre (12 mi) section east of Komsomolsk which was completed in 1974. In April 2008 the state-owned Bamtonnelstroy corporation started work on the new 3.91-kilometre (2.43 mi) single-track Kuznetsovsky Tunnel to bypass an older tunnel built in 1943–1945. It was opened in December 2012. The old tunnel had difficult gradients; building the new tunnel relieved a bottleneck on

434-521: The BAM as a Komsomol shock construction project , created the central Komsomol headquarters of BAM construction, and appointed Dmitry Filippov the chief of the headquarters. By the end of 1974, perhaps 50,000 young people of the 156,000 young people who applied had moved to the BAM service area. In 1975 and 1976, 28 new settlements were inaugurated and 70 new bridges, including the Amur and Lena bridges, were erected. And while 110 miles (180 km) of track

465-682: The BAM as a single operational body was dissolved, with the western section from Tayshet to Khani becoming the East Siberian Railway and the rest transferred to the management of the Far Eastern Railway . During the Russo-Ukrainian War , on November 30, 2023, an explosion occurred in the Severomuysky Tunnel . A second explosion happened soon thereafter on the bypass used as backup for

496-457: The BAM at Tynda is also referred to as the "Little BAM". During the winter the passenger trains go from Moscow past Tayshet and Tynda to Neryungri and Tommot and there are also a daily trains from Tynda to Komsomolsk-on-Amur and from Komsomolsk-on-Amur to Sovetskaya Gavan on the Pacific Ocean via Vanino ( "Vladivostok-Sovetskaya Gavan" train No.351Э). Travel time from Tayshet to Tynda

527-611: The BAM would be one of the two major projects in the Tenth Five Year Plan (1976–80). He famously stated that "BAM will be constructed with clean hands only!" and firmly rejected the suggestion to again use prison labor . A few weeks later, he challenged the Young Communist League ( Komsomol ) to join in "the construction project of the century". The 17th Komsomol congress (held in April 1974) announced

558-411: The BAM. The 59.8 bn roubles (about $ 1.93 bn) project included 20 kilometres (12 mi) of new track. In 2010, Yakunin had said, the stretch between Komsomolsk and Sovetskaya Gavan was the weakest link on the BAM, which, he said, could be carrying 100 million tons of freight a year in 2050. Running approximately alongside the railway track is the BAM road, a railway service track. It is said to be in

589-550: The century". If the permafrost layer that supports the BAM railway line were to melt, the railway would collapse and sink into peat bog layers that cannot bear its weight. In 2016 and 2018 there were reports about climate change and damage to buildings and infrastructure as a result of thawing permafrost. The BAM departs from the Trans-Siberian railway at Tayshet , then crosses the Angara River at Bratsk and

620-450: The finalisation of plans for upgrading the BAM for diesel or electric instead of steam traction, and for the heavier axle-loads of eight-axle oil tankers to carry new-found oil from Western Siberia. The upgrading required 25 years and 3,000 surveyors and designers, although much of the redesign work (particularly as regards the central section) took place between 1967 and 1974. In March 1974, Soviet General Secretary Brezhnev proposed that

682-583: The present-day BAM first came under consideration in the 1880s as an option for the eastern section of the planned Trans-Siberian railway. In the 1930s, labor-camp inmates, in particular from the Bamlag camp of the Gulag system, built the section from Tayshet to Bratsk . In a confusing transfer of names, the label BAM applied from 1933 to 1935 to the project to double-track the Trans-Siberian east of Lake Baikal, constructed largely using forced labor. 1945 saw

713-514: The rails to suit double-stacking under the overhead wires on the Russian gauge tracks, which requires rolling stock to be modified for service on the railway. At Tynda the route is crossed by the Amur–Yakutsk Mainline , which runs north to Neryungri and Tommot , with an extension to Nizhny Bestyakh opened in 2019. The original section of the AYaM connecting the Trans-Siberian at Bamovskaya with

744-489: The route, but today many of these places are deserted ghost towns and unemployment in the area is high. The building of the BAM has also been criticised for its complete lack of environmental protection. When the Soviet Union was dissolved , numerous mining and industrial projects in the region were cancelled and the BAM was greatly underutilized until the late 1990s, running at a large operational deficit. In 1996,

775-511: The short-term completion of the tunnel doubtful, although Russian president Dmitry Medvedev announced in November 2008 his support for a revival of this project. The BAM now also attracts the interest of Western railway enthusiasts, with some tourist activity on the line. Also, the BAM itself extension from Komsomolsk-on-Amur to Magadan (Okhotsk coastal route), full length electrification, full length track doubling, and double-stacking under

806-469: The town of Koanda. The road is passable only by the most extreme off-road vehicles and adventure motorcycles . In 2009, a group of three experienced motorcycle riders took a whole month to travel from Komsomolsk (in the east) to Lake Baikal . Main belt asteroid 2031 BAM , discovered in 1969 by Soviet astronomer Lyudmila Chernykh , is named in honor of the builders of the BAM. Tommot Tommot ( Russian : Томмо́т ; Yakut : Томмот )

837-414: The tunnel. The Security Service of Ukraine claimed responsibility for the explosions. A major improvement was the opening of the 15.34-kilometre (9.53 mi) Severomuysky Tunnel on 5 December 2003. It is up to 1.5 kilometres (nearly 1 mile) deep. Construction took 27 years to complete. Prior to this, the corresponding route segment was 54 km (34 mi) long, with heavy slopes necessitating

868-411: The use of auxiliary bank engine locomotives. With the resources boom of recent years and improving economic conditions in Russia, use of the line is increasing. Plans exist for the development of mining areas such as Udokanskoye and Chineyskoye near Novaya Chara , as well as one of Eurasia 's largest coal deposits at Elginskoye (Elga) in the Sakha Republic (Yakutia). In connection with this,

899-421: The whole route, only the western Tayshet- Taksimo sector of 1,469 km (913 mi) is electrified. The route is largely single-track, although the reservation is wide enough for double-tracking for its full length, in the case of eventual duplication. The unusual thing about the railway is that it is electrified with a 27.5 kV, 50 Hz catenary minimum height at 6.5 metres (21 ft 4 in) above top of

930-444: Was fully operational for civilians, due to military reasons. The BAM was again declared complete in 1991. By then, the total cost to build the line was US$ 14 billion ( RU₽ 106 trillion ). Beginning in the mid-1980s, the BAM project attracted increasing criticism for having been poorly planned. Infrastructure and basic services like running water were often not in place when workers arrived. At least 60 boomtowns developed along

961-408: Was laid, the track-laying rate would have needed to nearly triple to meet the 1983 deadline. In September 1984, a " golden spike " was hammered into place, connecting the eastern and western sections of the BAM. The Western media was not invited to attend this historic event as Soviet officials did not want any comments about the line's operational status. In reality, only one third of the BAM's track
