Northern Latitudinal Railway

Northern Latitudinal Railway is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Northern Latitudinal Railway rather than just read about it. In short: The Northern Latitudinal Railway (NLR; Северный широтный ход) is a Russian railway line previously under construction (construction is currently suspended) in the Yamalo-Nenets Autonomous District. It is 707 kilometres long, along the Obskaya - Salekhard - Nadym - Novy Urengoy - Korotchaevo route, which should link the western and eastern parts of the autonomous region, linking the Northern Railway in the east with…

Key takeaways

Northern Latitudinal Railway belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Northern Latitudinal Railway to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Northern Latitudinal Railway from memory before moving on to harder problems.

Reference excerpt

The Northern Latitudinal Railway (NLR; Северный широтный ход) is a Russian railway line previously under construction (construction is currently suspended) in the Yamalo-Nenets Autonomous District. It is 707 kilometres long, along the Obskaya - Salekhard - Nadym - Novy Urengoy - Korotchaevo route, which should link the western and eastern parts of the autonomous region, linking the Northern Railway in the east with Sverdlovsk Oblast. The project is run jointly by the Government of Russia, the governments of the Yamal-Nenets Autonomous District, PJSC Gazprom, JSC Russian Railways, and Development Corporation JSC. The construction coordinator of the railway is the Federal Agency for Rail Transport (Roszheldor). Construction of the NLR is planned to be carried out from 2018 to 2022. The estimated volume of traffic at completion is 24 million tons (mainly gas condensate and oil cargo). Initially, the highway was supposed to be laid by 2015, but due to the lack of a budget solution, the project completion dates were repeatedly postponed. In February 2017, the construction was announced to be completed in 2023. The project cost was estimated at 239 billion Rubles. In November 2022, it was announced that the government had suspended this project in favor of expanding rail eastward. To date, the project for the potential continuation of the infrastructure construction of the Northern Latitudinal Railway further east to the seaport of Dudinka, with subsequent interfacing with the Norilsk railway, has received the designation as the «eastern shoulder» of the NLR or the «NLR-2» project.

Project in strategic planning documents The strategic programs of Russian Railways approved in the spring of 2019 - a Long-Term Development Program until 2025 with an Investment Program attached to it - speaks only of «strengthening the infrastructure» of two railways, Northern and Sverdlovsk, «within the framework of the project to create the Northern Latitudinal Railway». Accordingly, no specific sections or directions are given, in contrast, for example, to the same South Siberian Railway, which was included in the «modernization» package of the Transsib and is reflected in the investment program of Russian Railways within the fairly clear boundaries of the Artyshta - Mezhdurechensk - Tayshet line. The state program «Socio-economic development of the Arctic zone of the Russian Federation», the last edition of which falls on the spring of 2020, does not clarify the understanding of the contours of the Northern Latitudinal Railway (undoubtedly one of the super-key infrastructure projects for the Russian Arctic). At the same time, curiously, the «Arctic» state program differs from Russian Railways in assessing the carrying capacity of the future line: from 20 million tons, given in the state program (and by 2020), to 23.9 million tons, declared in the investment program of Russian Railways. In the Spatial Planning Scheme of the Russian Federation in the field of federal transport, under the title of the Northern Latitudinal Railway, only the section Nadym - Pangody - Novy Urengoy - Korotchaevo is indicated. Construction on the Obskaya - Salekhard and Salekhard - Nadym lines is planned «within the framework of the investment project «Ural Industrial - Ural Polar»». On the whole, everything is correct, but in this case, the strategic planning document does not set at least the general boundaries of the Arctic railway corridor, considering it not as a complex, but in scattered details. And only in the departmental documents of the Ministry of Finance of Russia when approving budget classification codes for 2021 and for the planning period of 2022 and 2023. The northern latitudinal passage is finally taking shape: Obskaya - Salekhard - Nadym - Pangody - Novy Urengoy - Korotchaevo.

History The Salekhard–Igarka Railway was built between 1947 and 1953. It was not completed, although parts remained in use for many years. The railway included a ferry over the Ob River and, in winter, used seasonal tracks laid on the ice. After the railway west of Korotchaevo became unusable, the Yamal Railway Company was founded in 2003 and new road construction was planned. In 2005, the development of industry and transport in the Yamalo-Nenets Autonomous Okrug (YNAO) and the Ural Federal District spurred the creation of the Ural Industrial-Ural Polar project; the name Northern Latitudinal Railway first appeared. In 2006, the open joint-stock company Corporation Ural Industrial-Ural Polar was established to implement the project (since 2012, the OJSC Development Corporation). Since 2008, the project has been included in Russia's Strategy for the Development of Railway Transport. It includes:

Worked examples

Example 1 — a first encounter with Northern Latitudinal Railway

Start with the simplest possible case. Write down what Northern Latitudinal Railway claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Northern Latitudinal Railway before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Northern Latitudinal Railway ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Northern Latitudinal Railway

In research: Northern Latitudinal Railway appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Northern Latitudinal Railway in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Northern Latitudinal Railway is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arctic, Buildings and structures under construction in Russia, Proposed rail infrastructure in Russia, so understanding it makes those chapters shorter.
In everyday life: Look for Northern Latitudinal Railway outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
