Every matter is handled by a coordinated team of lawyers, legal staff and specialists. In property purchase matters we look at the contract, land register, escrow and tax consequences together.
A property beside a railway may be restricted under railway law even when the zoning appears suitable. Section 42 of the Austrian Railway Act 1957 generally covers a strip extending up to twelve metres from the centre of the outermost track at main lines, branch lines and non-public railways. Before making an offer, the buyer should know whether the planned building or another facility affects this area.
The review starts with a current site plan showing the track centre, station boundary and property boundary together. The danger area under section 43 Railway Act must also be considered. It has no uniform distance and may matter beyond the building prohibition area where a planned measure could affect the railway or safe railway operations.
This article focuses on public law restrictions. It separates them from private easements, general expropriation questions and noise claims. The practical focus is on permits, written agreements and purchase contract terms that should be clarified before signing.
Two questions show whether the relevant distances and railway law documents are already available.
Already know you want to get in touch? Go straight to the enquiry form.
Without these reference points, the twelve metre building prohibition area under section 42 Railway Act cannot be assessed reliably.
Request a current site plan, the track centre or station boundary data and any railway law decisions. The planned use should also be clarified with the railway company and the competent authority. The purchase contract can be drafted reliably only after this review.
Compare the documents with the actual project. The contract should expressly allocate the decision, agreement, safety measures and the consequences of a later deviation.
Oral information does not provide a reliable basis for a purchase. Before signing, the exception, permit or written agreement and the necessary safety measures should be clear. Depending on the facts, a condition precedent, retention or withdrawal right may be appropriate.
Section 42(1) Railway Act prohibits the construction of railway-external facilities of any kind up to twelve metres from the centre of the outermost track at main lines, branch lines and non-public railways. At stations, the station boundary is relevant and the additional twelve metre distance runs from that boundary. The measurement therefore does not automatically start at the property boundary or a visible fence.
The term railway-external facility is broad. It may cover a house, garage, retaining wall, storage area or other building installation that does not belong to railway operations. The purchase review must therefore relate to the specific project. A general expectation that permission will later be granted is not a substitute for reviewing the project itself.
Section 42(2) extends the rule to tramways on their own track in undeveloped areas. Under section 42(3), the authority may grant exceptions where this is compatible with public transport interests. A permit is not required under that provision where the railway company and the adjoining owner agree on the construction of the specific railway-external facility. The agreement should be documented in writing and describe the project.
The building prohibition area uses a fixed statutory distance. The danger area under section 43(1) Railway Act depends on the effect of a facility or action. Measures are prohibited when they may endanger the railway, railway equipment or the regular and safe operation of railway services and rail traffic. The provision also protects visibility of signals and level crossings.
A property can therefore be outside the twelve metre strip and still raise a railway law issue. Examples include an excavation, retaining structure, fill or storage that could destabilise the track or affect operations. Section 43(3) requires authority approval before quarries, dams or other facilities are built or explosive or flammable substances are stored or processed where the railway may be endangered.
In its decision 2 Ob 152/21y of 25 October 2022, the Austrian Supreme Court dealt with a forest road in the danger area of a railway that had been built without the required railway law approval. The practical lesson for buyers is clear: forestry or building permission does not automatically answer the separate railway law question.
The two protected areas use different criteria and lead to different contract questions.
| Area | Review standard | Contract consequence |
|---|---|---|
| Building prohibition area Up to twelve metres under section 42 | Clarify exception, permit or agreement | |
| Danger area Specific risk to railway or operations under section 43 | Review technical safeguards and approval | |
| Station Station boundary plus twelve metres | Record the boundary on the site plan | |
| Prohibited condition Removal may be ordered under section 44 | Allocate risk and costs expressly |
The public law review does not replace a technical assessment of the planned project.
A current land register extract, cadastral plan, site plan and project description belong together. The site plan should show the track, track centre, station boundary and planned facilities. If an existing building is involved, include extensions, fences, access routes, terraces and retaining structures.
Ask for railway law decisions, earlier agreements with the railway company and any conditions. An old decision may concern a different project or an earlier legal position. The relevant question is whether the existing or planned facility is covered and whether the safety measures were implemented.
The article on reading the land register extract explains how entries and encumbrances are reviewed. The article on building site declaration and zoning plans covers the planning law starting point.
Take care with standard clauses: A general statement that the buyer knows the condition of the property does not answer the railway approval question. The contract should describe the project, open documents and the consequences of a missing or later refused basis.
The contract depends on whether a facility already exists or a new project is planned. For an existing building, clarify which permits and agreements exist and whether later changes are covered. For a new building or extension, describe the intended use so the railway law review can relate to the actual project.
Possible terms include a condition precedent for the required exception or approval, a seller assurance about the existing legal basis, an allocation of safety costs and retention until the documents are produced. Purchase price maturity should also be coordinated with the documentation and the authority or contractual clarification.
The general purchase contract review page explains conditions, maturity and withdrawal consequences. The wording must match the site plan, project documents and the railway company information.
A common mistake is measuring from the property boundary. Section 42 Railway Act uses the centre of the outermost track or at stations the station boundary. A visual estimate from the property is not sufficient.
Another risk is treating zoning as proof of buildability. Zoning answers a planning law question. It does not replace the railway exception or a review of the danger area.
Contract drafts also often describe only a general building project. The review needs information on the building, height, ground changes, access, retaining structures and possible storage. The less precise the description, the harder it is to show whether an agreement or permit covers the actual project.
Finally, an oral statement by the seller or an agent should not be treated as a permit. A written agreement with the railway company should identify the correct contracting party, the project and the agreed safeguards.
Under section 42(1) Railway Act, the area generally extends up to twelve metres from the centre of the outermost track at main lines, branch lines and non-public railways. At stations, the station boundary is relevant and the additional twelve metres are measured from that boundary.
Section 42(3) allows the authority to grant exceptions. A permit is not required under that provision where the railway company and adjoining owner agree on the specific railway-external facility. The basis should be documented in writing and linked to the project before purchase.
Yes. The danger area under section 43 Railway Act has no uniform distance. Facilities or actions outside the fixed strip can still be prohibited if they endanger the railway or safe operations.
