South Africa’s freight rail sector is undergoing its most consequential structural transformation in decades with changes to the rolling stock acceptance framework requiring attention from train operators.
In August 2025, the minister of transport announced that 11 private Train Operating Companies (TOCs) had been granted conditional access to the national network across 41 routes and six freight corridors, formally opening Africa’s longest rail network to private operators. This rail liberalisation presents significant opportunities for private train operators, but success in the market is dependent on early preparation, thorough legal and technical advice, and a disciplined approach to regulatory compliance.
To govern the entry of rolling stock onto the network, the Railway Safety Regulator (RSR) has published South Africa's first dedicated draft Rolling Stock Acceptance Guide, giving effect to the Railway Safety Act, 2024. The guide draws together an interlocking matrix of obligations from multiple regulatory instruments, including the Transnet Rail Infrastructure Manager's (TRIM) Network Statement, the RSR's rolling stock certification guideline, and the South African National Standard 3000-1 series technical standards.
The guide is designed to assist TOCs in procuring new or existing rolling stock for operation on the South African railway network. It applies equally to rolling stock procured from local and international manufacturers or operators and sets out a phased approach for interaction between the RSR and TOCs, from the point of procurement or manufacture through to decommissioning.
At its core, the framework imposes four fundamental preconditions that every TOC must satisfy before its rolling stock can operate on the national network. This includes an obligation for all rolling stock to meet South Africa's specific gauge, loading, braking, and system interfaces. Each asset must have received formal approval from both TRIM, as infrastructure manager, and the RSR, as the independent safety regulator. Additionally, the rolling stock must be covered by a valid RSR safety permit at all times; and the TOC must operate and maintain its fleet in accordance with an approved safety management system.
Critically, these preconditions must be met prior to commercial operation and maintained continuously throughout the operational life of each asset, not merely established at the point of initial certification.
The RSR adopts a full lifecycle approach, meaning compliance extends from initial concept through to eventual decommissioning. Each phase depends on the submission, review, and approval of the one before it, creating a gating mechanism that operators must plan around carefully and build into their commercial and financing timelines from the outset.
The company will have to submit a notification to the RSR, which will review it and issue a notice of approval provided all requirements are met. The submission will be required to include a project definition and scope, the design standards to be used, and a hazard log and risk assessment managed by a competent person and counter-signed by all affected parties.
For second-hand rolling stock, operators must then submit documented evidence of standards, verification and validation tests, utilisation history, and commodity use history. An Approved Independent Assessor (AIA) must then be appointed to assess conformity to network technical requirements.
Submissions will be required to include a user requirement specification signed off by a competent person, and must demonstrate compatibility with the railway systemic environment, covering structural clearances, track gauge, track forces, electrical loading, and signalling compatibility.
Importantly, section 6.4.9 provides that specifications and drawings, including signalling and telecommunications systems, must be signed off by a registered professional in accordance with Engineering Council of South Africa (ECSA) requirements.
Section 7.3.2 provides that companies procuring rolling stock outside South Africa must arrange site visits to critical component suppliers where verification and validation tests can be witnessed by the RSR to ensure Reliability, Availability, Maintainability and Safety compliance concepts (RAMS) are complied with.
Section 7.3.4 provides for complex rolling stock projects; the firm must appoint an AIA to witness validation and verification tests at original equipment manufacturer facilities and submit a report to the RSR.
There is a distinct process for inspecting and testing of imported rolling stock and locomotives and will include procedures such as:
Section 8.2.xii requires test engineers to submit their ECSA registration, certification and a resume, while section 8.3.3 deals with imported rolling stock and that static inspections must be conducted at the harbour or entry yard where the rolling stock is received in South Africa, the inspection must be conducted by the AIA and witnessed by the RSR and the network owner.
Lastly, Section 8.3.6 is for locomotive, motor coach, and electric multiple units’ projects specifically, the RSR must appoint an AIA to witness testing and commissioning and submit a detailed report.
Once approved, the rolling stock is authorised for commercial use. It must be operated in accordance with an approved safety management system and remain compliant with all regulatory and infrastructure requirements.
However, the guide will provide that any envisaged changes during operations will have to be submitted to the RSR in advance, including the purpose, scope, methodology of implementation, training norms, acceptance criteria, and a risk assessment.
Ongoing maintenance must be carried out in accordance with approved maintenance plans and standards. The operator must ensure the asset remains safe, reliable, and compliant throughout its operational life; and
Section 10.1. provides a mechanism for the submission of changes, which must include proof of spares availability and proof that maintenance personnel are trained to maintain the system and operations personnel are trained to operate it.
Section 11 provides any material modification to rolling stock - technical, structural, or system related - requires reassessment and approval from the RSR. Changes cannot be implemented without regulatory oversight to ensure continued compliance.
Operators must consider the effects of the modification on the railway system, the effects of the environment on the modification, and ensure effective recording and communication of all changes, particularly where operational safety is affected.
At the end of its lifecycle, rolling stock must be formally withdrawn from service in accordance with regulatory requirements, ensuring safe disposal, deregistration and closure of compliance obligations.
The gating mechanism is the draft guide's most important feature. Each phase requires formal RSR sign-off before work proceeds, which means operators cannot commercialise their way past technical issues. For financiers and lenders, that structured audit trail is reassuring as it means the assets they are backing have been genuinely assessed. However, the draft guide is entirely silent on how long the RSR has to respond to each submission. For an operator with slot commitments and a project finance structure, an open-ended regulatory response window is a real commercial risk. That needs to be addressed in a future version.
Several important principles introduced by the guide will have direct practical consequences for TOCs entering the market and understanding them early is critical to avoiding avoidable delays.
There is no exemption for rolling stock already certified elsewhere. The guide applies equally to companies procuring rolling stock from international manufacturers or railway rolling stock operators, meaning that operators bringing proven assets from foreign fleets must still comply with the full submission process.
ECSA registration is also mandatory. Specifications and drawings must be signed off by a registered professional in accordance with ECSA requirements. International operators whose engineering teams are not ECSA-registered will need to address this before the design phase can be completed and the registration process itself takes time, meaning early identification of this requirement is essential.
Compliance is not a one-off event. The framework does not end at first approval. Any changes to monitoring and maintenance standards, procedures, processes, or agreements throughout the operational life of the asset require notification submissions to the RSR for approval. Maintenance strategies, service provider changes, and technology upgrades all carry ongoing regulatory notification obligations.
For locomotive, motor coach, and electric multiple units projects specifically, the RSR appoints an AIA to witness testing and commissioning and submit a formal report. This is mandatory, not discretionary, and adds both time and cost to the commissioning programme. RAMS compliance must be demonstrated by manufacturers at original equipment manufacturer facilities, witnessed by the RSR, and procurement teams and supply contracts must therefore explicitly require RAMS documentation as a deliverable from the outset.
One of the most underestimated practical risks in the draft guide is the ECSA registration requirement. International operators routinely assume that engineering excellence translates directly into regulatory compliance; however, this is not always the case. International operators routinely assume that engineering excellence translates directly into regulatory compliance it does not. South African law requires sign-off by an ECSA-registered professional, and that registration process takes time. Operators who do not identify and resolve this at the outset risk arriving at a phase gate they are simply not legally authorised to pass.
The guide is not without gaps. It is silent on RSR response timeframes at each phase gate, and it provides no recognition pathway for rolling stock already certified under comparable international standards both of which create real uncertainty for operators with commercial deadlines and financing obligations. The absence of any prescribed response timelines is a particular concern: without them, operators cannot build a reliable regulatory review window into their project schedules, and delays at any phase gate risk cascading through an entire programme.
The lifecycle approach is the correct model and long overdue. South Africa has historically treated rolling stock acceptance as a point-in-time event, and this guide formally extends regulatory oversight from concept to decommissioning. What is still missing is any recognition pathway for rolling stock already certified under comparable international standards. The draft guide requires full lifecycle documentation and an AIA appointment even for well-documented second-hand stock but provides no mechanism to credit prior international certification. That gap will slow market entry unnecessarily for operators bringing in proven rolling stock and is something the RSR should consider addressing in the next iteration of this guide.
The guide also does not define what constitutes "complex rolling stock" for the purposes of the AIA appointment requirement during the manufacturing phase. Greater clarity on this distinction is needed, and its absence leaves operators uncertain about the precise compliance obligations they will face when planning their procurement and commissioning programmes.
Those who treat compliance as a programme discipline rather than an administrative exercise, and who engage with the regulatory process earlier than they might assume is necessary, will be best placed to achieve commercial operations on time.
It should be noted that the current guide remains in draft form, and the industry awaits publication of the final version.
