Every matter is handled by a coordinated team of lawyers, legal staff and specialists. In construction cases we look at contract, evidence, deadlines and commercial consequences together.
Building, excavating or installing a retaining structure next to a railway requires two separate checks. General building law applies alongside the special rules protecting railway infrastructure and safe rail operations.
Section 42 of the Railway Act 1957 establishes a building prohibition area for railway-external installations. A project outside that area can still be relevant under section 43 if it affects the railway, safe operations or signal visibility.
This article explains which distances and documents matter before work starts, when an exception or written agreement with the railway undertaking becomes relevant, and how to prepare the building-law procedure in Salzburg.
Answer two questions about the location and planning status. You will receive initial guidance on the next documents to prepare.
Already know you want to get in touch? Go straight to the enquiry form.
The actual location, outermost track centreline, station boundary and planned installation are relevant.
Obtain an up-to-date site plan showing the track centreline, station boundary, property boundary and every planned intervention. Without these details, the building prohibition area under section 42 Railway Act 1957 cannot be classified reliably.
Record whether excavation, a crane, scaffolding, a retaining wall, storage or access could affect rail operations.
Section 43 Railway Act 1957 may apply outside the twelve-metre building prohibition area. The decisive issue is whether the installation or activity could endanger the railway, safe operations or the unobstructed view of signals.
Check height, depth, construction traffic, slopes, drainage, lighting and stored materials in addition to distance.
Have the preliminary design checked against the distance from the outermost track centreline and possible hazards. A later shift of the building can trigger new approvals and costs.
Pay particular attention to excavation, underpinning, crane position, site access and whether an exception or written agreement with the railway undertaking is required.
Assemble the site plan, submission drawings, excavation and safety concept, site layout and schedule. This allows you to determine whether a section 42 exception or a section 43 Railway Act review is needed in addition to building approval.
Consent from the railway undertaking does not automatically replace every building-law approval. Assign the two legal checks separately and record their conditions.
Section 42(1) Railway Act 1957 covers the construction of railway-external installations up to twelve metres from the centre of the outermost track for the railways named in the provision. At stations, measurement is taken from the station boundary. The Act calls this the building prohibition area.
The measurement therefore does not automatically start at the property boundary or visible fence. The site plan must show the outermost track centreline or station boundary. Only then can buildings, walls, fences, utility lines and other installations be classified.
Under section 42(3), the authority may grant an exception if it is compatible with public transport interests. The provision also recognises an agreement between the railway undertaking and the adjoining owner. Such an agreement should be written, tied to the plans and include the necessary safety measures.
Section 43(1) Railway Act 1957 does not rely on one blanket distance. It prohibits installations or other activities that could endanger the railway, regular and safe operations or traffic. This can apply even outside the building prohibition area.
For a building project, excavation depth, slope protection, vibration, dewatering, site traffic, lighting and signal visibility can therefore matter. A high fence and a crane may create different issues from an underground connection. The effect of each construction phase must be assessed.
Section 43 also contains approval requirements for certain dangerous installations and for explosive or flammable materials where an operational risk is possible. A civil-law agreement may replace the approval in the situations specified by the provision. The necessary precautions must remain clear and verifiable.
In Salzburg, first determine whether the project requires a building permit or notification under the Salzburg Building Police Act 1997. That check concerns building-law admissibility and the relevant building consent. It does not automatically answer whether railway rules also apply.
Conversely, an agreement with the railway undertaking does not remove every obligation to the building authority. Keep two checklists: one for the building, use, distances and submission documents, and one for track position, rail operations, safety measures, construction phases and railway contacts.
Contracts with planners and contractors should address the approval status, cooperation with safety conditions and the risk of redesign. Starting under time pressure can cause variations, delays and an uncertain evidentiary record.
One set of plans can trigger several checks. Their functions remain separate.
| Review level | Concrete question | Document |
|---|---|---|
| Building prohibition area Is a railway-external installation within twelve metres of the outermost track centreline or station boundary? | Surveyed site plan showing the track reference | |
| Danger area Could the works endanger the railway, operations or visibility? | Construction-phase and safety concept | |
| Building authority Which permit or notification does Salzburg building law require? | Submission drawings, description and authority file | |
| Agreement Which exception or written agreement is possible and which conditions apply? | Plan-based agreement with clear safety measures |
The competent authority and required evidence depend on the project and the railway installation.
The sequence reduces redesign and records responsibilities clearly.
Important: The twelve-metre rule in section 42 Railway Act 1957 is a measurement and prohibition rule, not a blanket answer for every project beside a railway. Section 43 can apply outside that area because of a concrete danger. A written agreement with the railway undertaking also does not automatically replace building approval.
For the first classification, prepare the current land-register and site plans, a surveyed track reference, submission or preliminary drawings, the building description and the construction schedule. For an excavation, add sections, support, underpinning and water-management plans.
Also establish the station boundary, railway installations, existing utilities, access routes and any earlier agreements. Photographs do not replace a survey, but they can document the initial condition usefully.
Assign each document its function. The building authority reviews building consent, while railway law addresses proximity to the railway and operational safety. Resolve conflicting plan versions before placing a binding order.
Section 44 Railway Act 1957 allows the authority, on application by the railway undertaking, to order the removal of an unlawful condition. This includes conditions created contrary to the statutory prohibitions or contrary to a civil-law agreement under sections 42 or 43.
Early coordination is therefore important. An informal approval at the site often leaves open which installation, phase and safety measure was meant. Written plans, minutes and clearances provide a stronger basis for continuing the work.
If construction has already started, secure the condition, plan version, correspondence with the railway undertaking and all authority letters. The correct response depends on whether approval is missing, a condition was breached or a concrete danger is alleged.
Section 42 establishes a building prohibition area of up to twelve metres from the outermost track centreline for the railways covered by the provision. At stations, the station boundary matters. Section 43 must additionally be checked for concrete dangers to the railway or operations.
No. An agreement may replace an approval in the specific situations set out in section 42(3) or section 43(4). It does not automatically replace a building permit under Salzburg law. Record the scope and safety conditions in writing.
Prepare a surveyed site plan, excavation sections, slope and underpinning details, water management, vibration and site-equipment information, construction phases, authority documents and the railway undertaking correspondence.
Secure plans, documents and the condition before the next step.
Separate building approval from heritage-protection approval.
Understand the consequences of authority orders and measures.
