Raideliittymät

Raideliittymät, also known as railway junctions or crossings, are points where two or more railway lines converge or diverge. These structures are essential for the efficient operation of rail networks, allowing trains to switch between different routes, access sidings, or change direction. The design and complexity of a raideliittymä can vary significantly depending on the volume of traffic, the speeds of the trains, and the specific operational requirements of the railway company.

Key components of a raideliittymä typically include switches (or points) that guide trains onto different tracks, and often signals that control train movements through the junction. The safe and reliable operation of these junctions is paramount, requiring meticulous maintenance and precise control systems. Different types of junctions exist, such as simple crossings where tracks merely intersect, or more complex layouts with multiple diverging and converging tracks and interlocked signaling. The term can also encompass level crossings where a railway line intersects with a road, though in a purely rail context, it refers to the meeting of two or more rail lines. Effective raideliittymä management is crucial for minimizing delays and maximizing the capacity of the railway infrastructure.
