PJM in "Eisenbahn-Ingenieur" Magazine: The Future of Vehicle Development

In the current issue of the trade journal Eisenbahn-Ingenieur (EI), February 2026, a technical article examines the increasing complexity in the development and maintenance of rolling stock. Authors Marius Müller (Specialist in Calculation, Fatigue Strength, and Welding Technology) and Wolfgang Konrad (Head of Calculation) from PJ Messtechnik demonstrate how to use interdisciplinary approaches to bring vehicles to the tracks safely and efficiently for a service life of 30 years or more.

Article Highlights:

Interdisciplinary Integration: The traditional authorization process according to the fourth railway package is significantly accelerated through the close integration of railway approvals management, calculation, simulation, design, and measurement technology. PJM operates as an accredited testing laboratory according to EN ISO/IEC 17025.

Focus on Welding Technology: A key success factor is the integration of welding design as early as the conceptual phase. PJM provides welding consultancy according to EN 15085-2, approval, and engineering from a single source, which massively reduces project effort for manufacturers.

Modern Verification Methods: In addition to the classic nominal stress approach, PJM increasingly relies on the notch stress concept. This allows for better utilization of structural reserves and ensures the reliable realization of the intended 30-year service life.

Practical Example – Bogie: PJM recently proved the efficiency of this approach during the development of a bogie frame, completed in early 2025. Through the cooperation of all departments, the goals of weight reduction and full robotic weldability were achieved within an ambitious two-year timeline.

Holistic Support: PJM supports customers throughout the entire life cycle—from the initial concept and authorization to maintenance and repair.

Certified Quality: Alongside accreditation according to ISO/IEC 17025 and welding certification according to EN 15085-2 for calculation and design, PJM’s membership in NAFEMS underscores the high standards for the validity and quality of its simulation processes.

The Experts' Conclusion: The tasks for engineering firms are becoming increasingly extensive. Only through motivated teams covering all areas—from simulation to final approval—can the complex requirements for modern rolling stock be met today.
