järnvägsrälsen

Järnvägsrälsen, often referred to as railroad track or simply track, is a permanent way on which railways operate. It consists of two parallel steel rails, typically laid on transverse sleepers or ties, which are themselves supported by ballast. This arrangement provides a smooth, low-friction surface for trains to travel on, guiding their wheels and distributing the load of the train to the ground.

The primary function of the rails is to carry the weight of the train and to guide its movement. The sleepers serve to maintain the correct distance between the rails, known as the gauge, and to transfer the load from the rails to the ballast. The ballast, usually crushed stone or gravel, provides a stable, well-drained foundation for the track structure, allowing for the dissipation of vibration and preventing the track from settling.

Modern railway tracks are highly engineered structures designed for durability, safety, and efficient operation. The type of rail, sleepers, and ballast used can vary depending on factors such as expected traffic volume, speed, climate, and ground conditions. Switches, also known as points, are a crucial component of the track system, allowing trains to change from one line to another. Signals are integrated into the track infrastructure to control train movements and ensure safety. The maintenance of järnvägsrälsen is a continuous process to ensure its integrity and performance.
