The fact that trams and metros operate safely is no accident, but the result of invisible, highly complex quality assurance. From the First Article Inspection (FAI) of critical components to the management of obsolete spare parts: a look behind the scenes of mobility safety, where experts guarantee the reliability of public transport with the strictest inspections and standards.

No original parts left for your fleet? When obsolescence threatens operations, reverse engineering is the strategic solution. Discover how worn-out components are transformed into approved and operationally reliable spare parts for transportation technology—ensuring your fleet keeps running reliably.

The mobility transition is on the right track—and it's won in the engine room. The best app remains theoretical if a train is stuck in the depot in the morning due to an aging door drive, an overdue wheelset, or an obsolete control module. For trams and metros, punctuality is decided at the interfaces between the workshop, dispatch, procurement, and specialized partners: from the spare part and its documentation to final approval. Here, "Mobility as a Team Effort" means thinking at the component level first, to keep operations running on schedule—regardless of whether the fleet is 5, 25, or 40 years old.

Durable tram fleets face the challenge of short-lived supply chains and obsolete electronics. The availability of critical spare parts is therefore a core strategic mission for public transport operators. Proactive obsolescence management, technical reverse engineering, and agile procurement logistics secure operational readiness and the urban mobility of tomorrow.

200 km/h, pressure wave impacts, and a 30-year service life: A train's windshield wiper is not an off-the-shelf product but safety-critical mechatronics. Learn everything about the technical details, procurement challenges due to obsolescence, and the vital lifecycle management for your fleet.

The fire protection standard EN 45545 often creates uncertainty in procurement and maintenance. Our article makes the complex requirements understandable in a practical way, explains key concepts like Hazard Level and R-Sets, and shows how to strategically use the standard to achieve maximum operational reliability and compliance in rail vehicle engineering.

Lightweight, extremely strong and often invisible: aramid fiber-reinforced plastics are the silent performers in transport and the environment. Find out in the practical guide where AFK (aramid) is indispensable, how it outperforms steel and what is important in procurement for maximum efficiency and safety.

More than just a carrier: the seat frame is a strategic component that determines the safety, longevity and operating costs of your fleet. Discover the crucial details from material selection to production and how you can ensure availability even with outdated parts - for maximum operational safety and cost-effectiveness over the entire life cycle.

Safety, durability, approval: choosing the right rubber profile is crucial. This practical guide highlights all the essentials - from material selection to the critical fire protection standard EN 45545. Your compact knowledge advantage for the reliable specification and procurement of sealing profiles.

Molded rubber parts are crucial for operational safety. Which elastomer is the right one? What to do with obsolete components? Our guide provides answers - from material selection and manufacturing processes to reverse engineering for maximum system availability.
