70 Kilometers of Noise Barriers Installed Along Railway Lines

The Deutsche Bahn has successfully erected approximately 70 kilometers of noise barriers along existing railway tracks over the past year. This marks an increase of nearly 15 kilometers compared to the previous year, as reported by the state-owned company. As of the end of last year, a total of 2,324 kilometers of railway lines have been soundproofed.

In addition to the barriers, about 2,000 residences in areas significantly affected by railway noise have been equipped with passive noise protection measures, primarily involving the installation of soundproof windows. The goal set by Deutsche Bahn and the federal government is to have approximately 3,250 kilometers of railway lines soundproofed by 2030. However, if the current pace of construction is maintained, this target is unlikely to be met. Starting from 2025, it will be necessary to construct over 150 kilometers of noise barriers annually, which is more than double the amount built in 2024.

To enhance noise protection, Deutsche Bahn is employing various strategies. These include the installation of noise barriers along existing tracks and providing support to residents to improve noise insulation in their homes, for instance, through the installation of new windows.

In 2024, the costs associated with these noise reduction measures amounted to approximately 176 million euros, which is funded through the federal budget. The federal government has been supporting noise mitigation efforts along railway lines since 1999.

In a notable development, residents in Hamburg have begun to benefit from innovative transparent noise barriers along the newly constructed S-Bahn line S4. These barriers offer the same level of sound protection as traditional walls but are made from clear plastic. This allows train passengers to see through the barriers while also improving the aesthetic experience for local residents, who no longer have to contend with imposing gray walls near their homes.

Initially, the transparent barriers were installed for testing over a distance of 55 meters. Further acoustic measurements are planned to assess their effectiveness in the coming months.
