Noise protection on railway lines

The noise from rail transport can quickly become a burden for residents. Heavily travelled railway lines with long-distance and freight trains in particular cause significant noise pollution. This makes it all the more important to protect the environment and local residents.

That is why there is the Traffic Noise Protection Ordinance, which, depending on the area, imposes noise protection requirements with barriers along railway lines. We will help you find the right noise barrier for your project!

This is why noise protection is particularly important in rail transport

Rail transport often causes noise pollution for the neighbouring regions. The level of this pollution is influenced by various factors: the number and type of railway vehicles, their speed, the exact type of track and the distance to the surrounding buildings are just some of the parameters.

In order to relieve residents, the immission limit values from the Traffic Noise Protection Ordinance must be complied with when building new railway lines and making fundamental changes to existing lines.

This means that, depending on the area category, certain decibel limits must not be exceeded. If measurements show that these limits have been exceeded, appropriate noise protection measures such as the installation of

Area category	Day (6:00 am to 22:00 pm)	Night (22:00pm to 6:00 am)
at hospitals, schools, convalescent homes and retirement homes	57 dB	47 dB
in pure and general residential areas and small housing estates	59 dB	49 dB
in core, village and mixed areas	64 dB	54 dB
in industrial estates	69 dB	59 dB

However, this regulation does not apply to existing railway traffic. In order to improve the noise situation in this area as well, the voluntary programme "Noise abatement on existing railway lines" has been in place since 1999. This noise abatement programme is intended to provide additional relief for cities, municipalities and residents and provide an incentive for more noise protection.

Correct noise protection therefore plays an important role in the area of rail transport, both in new construction and in refurbishment. Accordingly, you should include appropriate noise protection measures in your planning at an early stage.

The effect of noise barriers on railway lines

Without sound insulation

A noise barrier fulfils a shielding function. It is erected close to a noise source and thus prevents the sound from spreading to the regions behind it. Overall, noise reductions of up to 20 decibels are possible in this way, which can have a significant impact on the perception of noise.

How effective a noise barrier is for rail traffic in practice depends on factors such as height, structure and distance from the tracks.

With sound insulation

It also makes a difference whether only regional trains are travelling at low speeds on the tracks or whether long-distance or freight traffic is also taking place. Overall, noise barriers are the tried and tested means of significantly reducing noise pollution around railway lines.

Noise barriers for railway lines made of aluminium and acrylic glass

Noise barriers from Bongard & Lind are made of aluminium and optionally acrylic glass. It is up to you to decide whether the railway line is completely shielded by noise protection cassettes or whether transparent noise protection elements made of acrylic glass provide a view of the surroundings.

We offer you various design options, such as colours, shapes and motifs, to ensure that the noise protection blends in with the surroundings in the best possible way. As we manufacture all elements in our own factory, we can guarantee the highest quality. We can help you find the right noise barrier!

We offer those noise protection barriers:

	Type A3-e (DB-95) Soundproofing element made of aluminium Highly absorbent on one side
	Type A3-b (DB-95) Soundproofing element made of aluminium Highly absorbent on both sides
	Type A3-e (DB-95-L) Soundproofing element made of aluminium Highly absorbent on one side
	Type A3-b (DB-95-L) Soundproofing element made of aluminium Highly absorbent on both sides
	Type A3-r (DB-95-L) Soundproofing element made of aluminium Reflective glare and privacy protection
	Type A3-e (DB-88) Soundproofing element made of aluminium Highly absorbent on one side
	Type A3-r (DB-88) Soundproofing element made of aluminium Reflective glare and privacy protection
	Type T15 Transparent noise protection system with aluminium frame
