The new tracks within the city of Erfurt are being lined with noise barriers. Depending on the limit values, the noise barriers are two to three metres high. To minimise the noise close to its source, the barriers screen the line on both sides and between the tracks as well. Along some sections of line there are up to four noise barriers in parallel. The noise barriers have a total length of 5,500 metres from Bischleben to the central station.
