Construction of railways and underground railways

NACE code 42.12 covers the construction of railways and underground railways, a critical component of modern transportation infrastructure. This industry plays a vital role in facilitating the movement of people and goods, supporting economic growth and development across various sectors. As a specialized field within the broader construction industry, the construction of railways and underground railways requires a unique set of skills, techniques, and resources to ensure the safe and efficient operation of these complex transportation networks.

The construction of railways and underground railways involves a multi-step process that begins with thorough planning and design. This includes surveying the terrain, determining the optimal route, and designing the necessary infrastructure such as tracks, tunnels, bridges, and stations. Once the planning phase is complete, the construction process involves earthworks, such as excavation and grading, followed by the installation of the track system, including the laying of rails, sleepers, and ballast. Specialized equipment, such as track-laying machines and tunnel-boring machines, are often utilized to streamline the construction process. The final stages involve the installation of signaling systems, electrification, and the completion of any ancillary structures or facilities.

The construction of railways and underground railways requires a range of inputs, including raw materials such as steel, concrete, and aggregates for the track and infrastructure. Specialized machinery, such as excavators, cranes, and tunnel-boring equipment, is also essential. Additionally, this industry relies on skilled labor, including civil engineers, track-laying specialists, and construction workers, to execute the various stages of the project. Efficient project management and coordination between different teams and subcontractors are crucial to the successful completion of these large-scale infrastructure projects.

The primary output of the construction of railways and underground railways is the completed transportation infrastructure, which can then be utilized by 49.10 Passenger rail transport, interurban and 49.20 Freight rail transport operators. These railway and underground railway systems facilitate the movement of both passengers and goods, contributing to the overall efficiency and connectivity of the broader transportation network. The construction of these assets also supports economic growth and development by enhancing accessibility and reducing transportation costs for businesses and individuals.
