When theory meets real engineering practice, solutions are created that move. This is exactly what the cooperation between FIBRO and the four-member team of mechanical engineering students "Next Stop: Innovation!" from Ostfalia University of Applied Sciences at the current European Railway Challenge (ERC) shows.

A challenge with ambition

Since 30.11.2025, teams from all over Europe have been working on miniaturised rail vehicles that have to prove themselves in various disciplines. One of the most technically demanding tasks: The Automatic Coupler Challenge. Here, an automatic coupling and uncoupling process must not only function in principle, but must also be reproducible, reliable and safe under realistic dynamic conditions. What in reality concerns trains weighing several tons is transferred to the scale of a miniature vehicle in the competition – with the same physical principles. Here, too, considerable kinetic energies are generated during the dome joint. According to the team's calculations, forces of up to 17 kN can occur. This means an enormous burden for mechanics and especially for sensitive sensors and electronics.

Controlled control of energy:

Industrial know-how meets young engineers In automatic coupling, two moving masses collide. The kinetic energy must be absorbed in a very short time and dissipated in a controlled manner. As an industrial partner, FIBRO supports the team with know-how from elastomer and damping technology and has contributed suitable damper elements from the G 2450.20 series for the clutch design. These absorb the energy that occurs on impact and significantly reduce load peaks. The result: Mechanics as well as sensors/electronics are protected and a reproducible, reliable coupling process is made possible. In addition, driving dynamics and component service life benefit from smoother acceleration and braking.

The project shows how industrial solutions can be transferred to innovative applications – even on the scale of a competitor's vehicle. Because the underlying principle is universal: Wherever dynamic loads, shock loads, vibrations and reproducible motion sequences play a role, coordinated damping solutions ensure safety, precision and durability.

Whether mechanical engineering, automation technology or railway technology – controlled force absorption is a decisive factor for system performance. Suspense until the evaluation in June 2026

The European Railway Challenge is currently still ongoing. From 05.–07.06.2026, the projects will be presented and evaluated in Bad Schussenried. We are following the results with great excitement. One thing is already certain: this project is a strong example of how practical engineering expertise, the promotion of young talent and industrial application work together.
