Track laying is the process of installing railway tracks, which involves placing steel rails on a prepared foundation called the track bed. This foundation is typically made of crushed stone, known as ballast, which helps to support the weight of trains and maintain track stability. Workers use specialized equipment to align and secure the rails, ensuring they are straight and level for safe train travel. Once the rails are in place, they are fastened to wooden or concrete ties, which help distribute the weight and keep the track in position. Proper track laying is essential for the safety and efficiency of rail transport, impacting the performance of trains like those operated by Amtrak or Union Pacific.
