Subway construction involves building underground train systems that help transport people efficiently in urban areas. This process includes digging tunnels, laying tracks, and creating stations. Engineers and construction workers use heavy machinery to excavate the ground and ensure safety during the project. Once the tunnels are completed, workers install electrical systems, ventilation, and other essential infrastructure. The construction of a subway system can take several years and requires careful planning to minimize disruption to the surrounding community. Successful subway construction can significantly improve public transportation and reduce traffic congestion in cities.
