Railroads are typically built by specialized construction companies that focus on civil engineering and infrastructure projects. These companies often work in collaboration with government agencies, private investors, and railway operators. The process involves extensive planning, surveying, and construction of tracks, bridges, and stations, often following specific regulations and standards set by regulatory bodies. Additionally, various contractors may be involved in different aspects, such as signaling and electrification systems.
