Contact Antje Freitag at the Berlin office
Antje Freitag is Teamleader Safety System Development at NEXTRAIL GmbH. She has been working as an engineer in the field of functional safety for railway applications at NEXTRAIL GmbH since 2017. She has extensive experience in national and international railway projects, with a focus on RAMS management by EN 50126. From hazard, risk, and CSM analysis, RAMS, and project management to verification & validation, Antje Freitag's high level of expertise covers the entire range of safety requirements in the railway sector. She also has in-depth knowledge of the complex procedures in the approval processes.
Antje Freitag laid the foundation for her high level of expertise back in 2013 with her consistent focus on the area of functional safety for railway applications by the EN 50126 standard. At the beginning of her professional career, she successfully worked for one of the largest German engineering companies in the area of safety management for railway customers by EN 5012x. Today, she is responsible for challenging infrastructure projects and development projects in a leading role. She combines her methodical expertise in carrying out risk and hazard analyses with her in-depth knowledge of the complex approval processes in the railway sector.
Antje Freitag is characterised by her many years of experience and her sound methodology, which she successfully applies to a wide variety of projects and safety issues in railway technology. Her comprehensive expertise in functional safety enables her to make a significant contribution to the targeted development and implementation of our customers' safety-relevant systems.

The Advanced Protection System (ASP) is a central component of the future Advanced Digital Infrastructure (ADI) in rail transport. With the introduction of this new protection logic by ETCS, the closely synchronised movement of rail vehicles at an optimum distance (moving block) is made possible. This means a move away from the traditional block-centred spacing towards a train-centred spacing, whereby the train as a safety object comes to the fore.
As part of the APS project, Antje Freitag works as RAMS Manager and internal team leader at NEXTRAIL to support DB and its industry partners:
- Supporting Safety Management in the creation of safety documentation by EN50126 Phase 1-4.
- In addition, NEXTRAIL is developing cross-divisional test cases for the Moving Block Demonstrator at the European level in the R2DATO project in the Innovation Pillar.
As part of the Digitaler Knoten Stuttgart (DKS) project, the trackside ATO Centre system is being further developed and prepared for use throughout Germany.
NEXTRAIL is supporting Deutsche Bahn in key areas such as the digitalisation of the rail system, system development for highly automated driving and the creation of technical and procedural documents as well as process support.
Antje Freitag is involved in this DB innovation project as a project team member in the area of safety management in the following areas in the creation of safety documentation by EN50126 for the developed ATO GoA2 generic system as part of the DKS project:
- CSM-RA
- Security plan
- RAM analysis
- Security Integrity Assessment
- risk analysis
- and the authorisation documentation.
With the commissioning of the Stuttgart Digital Node (DKS) in 2026, Deutsche Bahn is defining the parameters for the digital transformation of the railway in Germany. In this project, all technologies from DSTW, ETCS, IT security, bbIP and various peripheral systems will be equipped together for the first time at a central German railway node and introduced in regular operations.
NEXTRAIL is supporting the project in the area of safety management with the following activities:
- Creation and maintenance of the safety plan and the technical review of the phase-related documents by EN 50126
- In addition, Antje Freitag's team is supporting the creation of standard-compliant templates as well as the hazard protocol (phase 3) and the proof of safety from phase 6 (preliminary) and phase 9 (final).
NEXTRAIL supported SBB in the development of a new type of architecture based on geometric logic for control and signalling technology (LST). The long-term goal is to increase track capacity and thus SBB's competitiveness. The focus was on (partially) automatic project planning (EDP) and Topo4:
- In the EDP sub-project, NEXTRAIL supported the development of a faster, as well as partially automated, project planning process for SmartRail 4.0, focusing on the ETCS interlocking and the connected systems such as the Object Controller.
- As part of this project, NEXTRAIL created documentation by CENELEC phases 1-5 for the TOPO4 and AMP sub-projects across all departments.
