Railway screens

Railway screens

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.​​

​Curved reflective screen

The most used screen is curved, and precisely the curved design means that a significant part of the noise is reflected back to the track, where it is collected in the shards. The screen surface itself consists of galvanized steel plates bent like “hat profiles” and bolted together to form one tight surface. The top of the screen is finished with a top fender. The column spacing for this screen type is normally 5 meters.

​Vertical absorbent screen

Where the curved reflective screen cannot be used, for example due to reduced distance to the track or due to placement along the edge of the platform, a vertical screen with absorbent properties is used instead. 

The screen is constructed as a curved screen of bent screen plates made of galvanized steel. An insulating material is placed inside the “hat profiles”, which is subsequently protected with a net of expanded metal. The column spacing for this screen type is normally 5 meters.

Vertical glass screen

If there are special visual conditions to be taken into account, transparent screens can be used, where the upper screen plates are replaced by glass sections. The column spacing for this type of screen is usually 2.5 meters.

DAV NORDIC has its own fitters and project managers who are specially trained and approved to work on and around the railway. This means that we have experience working with safety plans, track technicians, track closures and SR manager.
