The Luxembourg Rail Protocol

The Luxembourg Rail Protocol is the rail-specific Protocol to the 2001 Cape Town Convention on International Interests in Mobile Equipment. It creates a uniform international legal regime for security interests in railway rolling stock — analogous to the regime the Aircraft Protocol established for aircraft equipment — and backs it with a dedicated International Registry for the perfection and prioritisation of those interests. The Protocol was adopted in Luxembourg on 23 February 2007 and entered into force on 8 March 2024.

What the Protocol does

The Protocol, read together with the Cape Town Convention, establishes a free-standing international interest in railway rolling stock that is recognised, registrable and enforceable across Contracting States. Three categories of interest are covered:

the interest of a lessor under a leasing agreement;
the interest of a creditor under a security agreement (secured loan); and
the interest of a conditional seller under a title-retention agreement.

Each of these is registered in the International Registry maintained under the Protocol. Priority between competing interests is determined by order of registration. The Convention-level default and insolvency remedies (including the ability for the creditor to take possession, sell, or lease the equipment, and the effect on subsequent insolvency proceedings of the debtor) apply — modulated by the declarations a Contracting State has made on accession.

The International Registry

The International Registry for Railway Rolling Stock became operational in parallel with the Protocol’s entry into force. It is an electronic, 24/7-searchable priority register, accessible at rollingstockregistry.com. Rolling stock is identified via the Unique Rail Vehicle Identification System (URVIS) developed for the Protocol, which is designed to coexist with the European Vehicle Number (EVN) used in the European register of authorised vehicles (ERATV / ECVVR).

The Registrar is supervised by a Supervisory Authority constituted under Article 12 of the Protocol, with OTIF (the Intergovernmental Organisation for International Carriage by Rail) acting as its Secretariat. The Supervisory Authority is based in Berne.

Why it matters for rolling-stock financing in Germany

For cross-border rolling-stock finance the Protocol offers three practical advantages where both jurisdictions are Contracting States or where there is an appropriate connecting factor under Article 3 of the Cape Town Convention. First, a single internationally recognised registration delivers priority vis-à-vis competing secured creditors across all Contracting States, removing the need to rely exclusively on local perfection. Second, the Convention’s default-remedies regime, including the 60-day «Alternative A» insolvency remedy favoured by the OECD-backed Rail Working Group, can reduce the uncertainty and cost of enforcement on operator insolvency — an uncertainty that feeds directly into debt pricing. Third, the Registry creates a clean record of international interests that can be diligenced on refinancing or vehicle re-deployment, which matters particularly where pool structures and Wiedereinsatzgarantien are in play. As long as Germany has not ratified (see Status in Germany below), purely domestic German transactions do not benefit from these advantages directly; cross-border structures generally do.

The Protocol does not displace the German or EU regulatory regime. It sits alongside the sector frameworks described elsewhere on this site — the PSO framework under Regulation 1370/2007, the state-aid discipline under Article 93 TFEU and the Altmark criteria, the market-access regime under Directive 2012/34/EU and the ERegG, and the safety, authorisation and ECM regimes under the Fourth Railway Package. In practice, the Protocol is a proprietary-law overlay: it affects how rights in the vehicle survive change of operator or insolvency, but it does not change how the Verkehrsvertrag is procured, how state aid is assessed, or how the operator is licensed.

COTIF and the OTIF family of instruments

The Luxembourg Rail Protocol is distinct from, but institutionally connected to, the Convention concerning International Carriage by Rail (COTIF) and its Appendices — CIV (passengers), CIM (goods), RID (dangerous goods), CUV (use of vehicles in international traffic), CUI (use of infrastructure), APTU (technical standards) and ATMF (admission to operation of railway material). COTIF and its Appendices concern the operation of international rail services; the Luxembourg Rail Protocol concerns the proprietary and security-interest treatment of the underlying assets. OTIF is the institutional bridge between the two: it administers COTIF and, separately, provides the Secretariat to the Supervisory Authority of the Luxembourg Rail Protocol.

Ratification and implementation status

The Protocol entered into force internationally on 8 March 2024 once the required number of ratifications was reached. The European Union acceded to the Protocol for matters within its exclusive competence, but individual Member States continue to ratify for matters within national competence at their own pace, and the list of declarations under Articles XXVII–XXXII shapes what actually applies in each jurisdiction.

Because the ratification landscape is still evolving, the authoritative current list of Contracting States, their declarations and their effective dates should be taken from the OTIF Luxembourg Rail Protocol page rather than relied on from memory. For deals touching rolling stock used in international traffic, the applicable declarations — in particular those on insolvency remedies (Alternative A vs. B), public service exemption, and exemption of specified rolling-stock categories — should be checked at signing.

Status in Germany

Germany has signed the Luxembourg Rail Protocol on 21 November 2012 but has not yet ratified it. Germany is therefore not a Contracting State to the Protocol in its own right, and the stand-alone German ratification instrument (Vertragsgesetz under Art. 59(2) GG, together with any accompanying adjustments to the BGB and the InsO) is still outstanding. In practical terms this means that the Protocol’s harmonised priority rules for international interests and, in particular, the 60-day insolvency remedy under «Alternative A» of Article IX do not apply directly in a German insolvency proceeding; the treatment of a creditor’s rights in an aircraft-style Alternative A window under German law would require a ratification with a corresponding declaration.

The Protocol is nevertheless not without effect in Germany. The European Union acceded to the Protocol in 2014 for matters within its exclusive competence — essentially the regime of jurisdiction and recognition under Article 81 TFEU — and to that extent the Protocol’s provisions apply in Germany as in any other Member State. For German rolling stock refinanced by lessors domiciled in a Contracting State (or in any cross-border structure with an appropriate connecting factor), a registration in the International Registry remains a meaningful step: priority vis-à-vis competing secured creditors and the Registry’s search record continue to be internationally recognised. In a purely domestic transaction between German parties over rolling stock operated in Germany, the Protocol does not presently displace German property and insolvency law.

Deals that touch German operators, German-domiciled pool vehicles or German-law-governed security should therefore continue to rely on the German sachenrechtliche regime (Sicherungsübereignung, §§ 929, 930 BGB; Lease §§ 535 ff. BGB; insolvency rights under §§ 47 and 50 InsO) and to treat any comfort from the Luxembourg Rail Protocol as an international overlay that applies only insofar as the deal has a connecting factor to a Contracting State.

The unresolved Art. 43 / 45 EGBGB question for cross-border wagons

Ratification aside, the Protocol responds to a problem that German private international law has not solved cleanly for railway rolling stock. Under Art. 43(1) EGBGB, rights in rem over movables are in principle governed by the law of the situs — an awkward rule for rolling stock that crosses borders on a daily basis. Art. 45 EGBGB contains a special rule for aircraft, water vessels and railway vehicles, referring those rights to the law of the Herkunftsstaat. The traditional reading of «Herkunftsstaat» for a rail vehicle is the state that issued the national operating licence and in whose national vehicle register the vehicle was entered. After the Fourth Railway Package, vehicle authorisation sits at the ERA One-Stop-Shop under Directive (EU) 2016/797 and Implementing Regulation (EU) 2018/545, while registration is distributed across national registers interfacing with ERA's European Vehicle Register; the first authorisation is no longer a national licensing act in the pre-2016 sense. Kühl/Simsa (WM 2021 Heft 46, 2224) have argued that this makes the classical interpretation of Art. 45 EGBGB for freight wagons difficult to apply, and proposed anchoring the connecting factor on the state identified by the country code of the European Vehicle Number (EVN) — i.e. the state of registration in the NVR — so that cross-border transfers of freight wagons can be performed with a predictable law-of-the-register rule until the Luxembourg Rail Protocol is ratified with a Vertragsgesetz. The problem they identify is the practical argument for a German ratification: a Protocol regime based on the International Registry and on URVIS-indexed searchable priority would make the Herkunftsstaat debate under Art. 45 EGBGB largely moot for rolling stock registered in a Contracting State.
