Rail tracks are the pathways on which trains travel. They are made of steel and consist of two parallel lines, known as rails, that are supported by ties and ballast. The design allows trains to move smoothly and safely at high speeds, connecting various locations across cities and countries. The construction of rail tracks involves careful engineering to ensure stability and durability. Switches and signals are also part of the system, allowing trains to change tracks and communicate their status. Overall, rail tracks are essential for efficient transportation and play a crucial role in the railway network.
