lyöntikiskoihin

Lyöntikiskoihin, literally meaning "to striking rails" or "to hitting rails" in Finnish, refers to a specific type of maintenance and construction work on railway tracks. This process involves the mechanical joining of individual rail sections into longer, continuous lengths. Traditionally, rails were joined with fishplates, creating joints that were a source of noise, wear, and potential failure points. The introduction of thermite welding and other continuous welding techniques allowed for the creation of longer welded rail strings, which significantly improved track quality and reduced maintenance.

Lyöntikiskoihin encompasses the various methods used to achieve this continuous rail. Thermite welding is a common technique where a molten metal mixture is used to fuse the rail ends together. Electric flash-butt welding is another method, often performed in specialized plants or on-site. The goal is to create a smooth, continuous surface for trains to travel on, minimizing vibrations and improving passenger comfort. This process is crucial for modern railway operations, contributing to increased speeds, reduced wear on rolling stock, and a safer, quieter track. The term is used in the context of railway infrastructure maintenance and renewal projects.
