Rail transport in Mongolia

Rail transport is an important means of travel in the landlocked country of Mongolia, which has relatively few paved roads. According to official statistics, rail transport carried 93% of Mongolian freight and 43% of passenger turnover in 2007. The Mongolian rail system employs 12,500 people. The national operator is UBTZ (Ulaanbataar Railway, Улаанбаатар төмөр зам), traditionally also known as Mongolian Railway (MTZ, Монголын төмөр зам). This can be a source of confusion, since MTZ is a distinct company established in 2008. The Mongolian Railway College is located in Ulaanbaatar.

Routes
The Trans-Mongolian Railway connects the Trans-Siberian Railway from Ulan Ude in Russia to Erenhot and Beijing in China through the capital Ulaanbaatar. The Mongolian section of this line runs for 1110 km. The Trans-Mongolian Railway runs through Mongolia on Russian gauge track, changing to standard gauge track after entering China. There are several spur lines: to the copper combine in Erdenet, to coal mines in Sharyngol, Nalaikh and Baganuur, to the fluorspar mine in Bor-Öndör, to the former Soviet military base and refinery at Züünbayan. Another line links Züünbayan with Khangi on the Chinese border.

A separate railway line exists in the east of the country between Choibalsan and the Trans-Siberian at Borzya; however, that line is closed to passengers across the Mongolia-Russia border; passenger trains terminate at Chuluunkhoroot (Ereentsav). This line used to have a spur line to the uranium mine at Mardai, however this spur line was torn up and sold in the late 1990s/ early 2000s.

For domestic transport, daily trains run from Ulaanbaatar to Darkhan, Sukhbaatar, and Erdenet, as well as Zamyn-Üüd, Choir and Sainshand. Mongolia uses the (Russian gauge) with a total system length of 2810 km. The Mongolian Railway (MongolRail) is slated to cover 7588 km by year 2025. The coverage track distance will get increased by 4778 km. Mongolian railways transported 20.5 million tons of freight in 2013, which is close to the system's full capacity. Transporting transit cargo between Russia and China is an important source of revenue for the country's railway system; in addition to this, railways are used to transport domestic coal to power plants. As of November 2023, Tavantolgoi-Zuunbayan railway and the Khangi-Mandal crossing on Mongolia’s border with China has been completed adding 226.9km (140 miles) across the south-east of Mongolia.

Proposed lines
A 2010 Mongolian government plan proposed 5683.5 km of new track, for the primary purpose of connecting Dalanzadgad and Choibalsan, to be built in three stages:


 * the first stage, totaling 1100 km and linking Dalanzadgad–Tavan Tolgoi mine–Tsagaan Suvarga mine–Züünbayan (400 km), Sainshand–Baruun-Urt (350 km), Baruun-Urt–Khööt mine (140 km), and Khööt–Choibalsan (200 km);
 * the second stage, totaling 900 km and connecting the first stage with the Chinese border, linking Nariin Sukhait mine–Shivee Khüren (45.5 km), Tavan Tolgoi–Gashuun Sukhait (267 km), Khööt–Tamsagbulag–Nömrög (380 km), and Khööt–Bichigt (200 km); and
 * the third stage, totaling 3600 km) and not described in detail, but including a link with Tsagaannuur on the Russian border and a line from Ulaanbaatar to Kharkhorin.

In 2012, a line connecting Erdenet–Mörön–Ovoot mine–Arts Suuri on the Russian border (547 km) was approved, but never built. In 2014, it was announced that the planned Tavan Tolgoi–Gashuun Sukhait and Khööt–Bichigt lines were to be of Chinese gauge, while the Dalanzadgad–Choibalsan, Khööt–Nömrög, and Erdenet–Artssuuri lines were to be of Russian gauge. In 2016, a line linking Züünbayan to Khangi on the Chinese border (280 km) was approved; it was completed in 2023. A 2017 government plan, greatly reduced in scope from the 2010 one, proposed linking Khööt–Choibalsan, Nariin Sukhait–Shivee Khüren, Khööt–Bichigt, and Züünbayan–Khangi.

Rolling stock
As Mongolia's railroads are not electrified, UBTZ relies entirely on Diesel traction. Most common locomotives are M62 variants, including five rebuilt 2Zagal (two white horses) double engines. Other engines include TEM2 and TE116 variants, Dash-7 and one Evolution locomotive on lease from GE. In October 2010, Ulaanbaatar Railway ordered 35 2TE116UM diesel freight locomotives from Transmash.
