kylmäkiskojen

Kylmäkiskojen, a Finnish term, translates to "cold rails" or "cold tracks" in English. It refers to a specific type of infrastructure used in some railway systems, particularly in colder climates. These cold rails are not for trains to run on in the traditional sense, but rather serve a crucial role in managing the temperature of the track bed and the surrounding environment.

The primary function of kylmäkiskojen is to mitigate the effects of extreme temperature fluctuations on railway lines. During hot summer months, conventional tracks can experience significant expansion, leading to stress and potential buckling. Conversely, in freezing winter conditions, ice and frost can form, affecting track stability and potentially damaging components.

Kylmäkiskojen are designed to absorb and dissipate heat during warmer periods, helping to keep the track bed cooler. In colder weather, they can be used in conjunction with other systems to prevent excessive freezing or to aid in de-icing. The exact design and implementation of kylmäkiskojen can vary, often involving specialized materials or integrated cooling/heating elements. Their presence is a testament to the engineering challenges faced in maintaining reliable railway operations in regions with harsh climates. The goal is to ensure the structural integrity and safe operation of the railway throughout the year, regardless of extreme weather events.
