Along train tracks and at stations there is a great need for shielding, both for noise and to preserve privacy. Therefore, you will often see some massive and loud noise screens. These can have different designs according to needs and possibilities, but most often consist of galvanized steel sheets.
Banedanmark, an agency under the Ministry of Transport in Denmark, builds, develops and maintains the railway network in Denmark. They operate with three different screen types, all of which are generally described in the "Installation manual for Banedanmark's standard screens".
What the screens have in common is that they are primarily made of a galvanized steel construction built with load-bearing vertical columns, between which horizontal screen surfaces are mounted. Material thickness and profile dimensions of the individual steel parts depend on the actual loads from wind pressure, suction/pressure from trains and any ground pressure.
If the screen is mounted in the ground, the lower part of the screen is dug into the ground to ensure that it is completely soundproof. If the screen is mounted on a construction (steel sheeting, concrete wall, etc.), the aim is to make a soundproof connection to this construction. A Banedanmark screen usually has a height of 2m from the top of the rails to the top of the screen. This ensures a clear view of the train's passengers across the screen.
