relægning

Relægning is a Danish term that translates to "laying of relay points" or "re-laying" in English. It is most commonly associated with the railway industry, referring to the process of replacing old or worn-out railway tracks with new ones. This involves a systematic approach to ensure the smooth and safe operation of trains.

The process typically begins with the removal of the old track sections. This can include the rails, sleepers (or ties), and ballast. Once the old track is cleared, the new track components are brought into place. This often involves specialized track-laying machines that can efficiently position new rails and sleepers. The ballast, which is the crushed stone or gravel bed beneath the track, is then adjusted or replaced to provide a stable foundation.

Relægning is a crucial maintenance activity that ensures the structural integrity and safety of railway lines. It addresses issues such as rail wear, track deformation, and ballast degradation, all of which can negatively impact train speed, ride comfort, and overall safety. The frequency of relægning depends on factors like traffic volume, train speeds, and the type of track construction. Modern relægning techniques aim to minimize disruption to train services by employing efficient methods and often working during scheduled off-peak hours or overnight.
