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, connecting communities, and supporting economic growth across various sectors. As a specialized branch of civil engineering, the construction of railways and underground railways requires a high level of technical expertise and coordination to ensure the safe and efficient operation of these complex transportation systems.

The construction of railways and underground railways involves a series of interconnected processes. It typically begins with the planning and design phase, where engineers and project managers determine the optimal route, track layout, and infrastructure requirements. This is followed by the site preparation stage, which may involve land clearing, earthworks, and the construction of bridges, tunnels, and other supporting structures. The installation of the track system, including the laying of rails, sleepers, and ballast, is a critical step that requires precision and attention to detail. Finally, the construction process culminates in the installation of signaling systems, electrification, and other specialized equipment necessary for the safe and reliable operation of the railway or underground system.

The construction of railways and underground railways relies on a range of inputs, including raw materials such as steel, concrete, and aggregates for the track and supporting infrastructure. Specialized machinery, such as excavators, cranes, and track-laying equipment, is also essential for the various stages of the construction process. Additionally, this industry requires a skilled workforce, including civil engineers, project managers, and construction workers, to ensure the successful completion of these complex projects.

The primary output of the railway and underground railway construction industry is the completed transportation infrastructure, which can be utilized by various 49.10 Passenger rail transport, interurban and 49.20 Freight rail transport operators. These transportation systems facilitate the movement of both passengers and goods, contributing to the overall efficiency and connectivity of the broader economy. The construction of railways and underground railways also supports the activities of 42.11 Construction of roads and motorways and 42.13 Construction of bridges and tunnels, as these complementary infrastructure projects often work in tandem to create a comprehensive transportation network.
