Railroad ties, also known as railway sleepers, are sturdy wooden or concrete beams that support the weight of train tracks. They help maintain the alignment of the rails and distribute the load of passing trains, ensuring a stable and safe railway system. Typically placed perpendicular to the rails, railroad ties are essential for preventing track deformation and maintaining proper gauge. In addition to wood and concrete, some ties are made from recycled materials, contributing to sustainability in the transportation industry. Proper maintenance and replacement of these ties are crucial for the longevity of the railway infrastructure.
