Locking solutions for rail vehicles and railway technology

Challenges

Challenges for rail vehicles

The rail sector places some of the highest demands on materials and functionality. The key challenge is fire protection in accordance with EN 45545. Every component, from the seal to the handle, must strictly comply with limit values regarding flammability, smoke emission, and toxicity.

From a mechanical standpoint, locks in outdoor environments are subjected to extreme pressure and suction forces, particularly when passing through tunnels at high speeds. These cyclic loads can cause conventional mechanisms to loosen.

In the passenger compartment, on the other hand, the focus is on protection against vandalism and accident prevention (no sharp edges, flush installation).

In addition, the components must be designed to last 30 years or more, as maintenance intervals are long and downtime in rail operations is extremely costly.

Solutions

Our solutions for rail vehicles

STUV provides solutions specifically validated for rail transport technology.

Our products are made from fire-resistant materials and are certified to the latest fire safety standards.

To withstand the enormous aerodynamic forces encountered outdoors, we use high-strength stainless steel compression latches that ensure a secure mechanical lever that won’t loosen even under the most intense vibrations.

For the interior, we have developed flush-mounted swinghandles that not only blend aesthetically with the modern train design but also leave no surface vulnerable to vandalism.

We place the utmost importance on material quality to minimize wear and tear over decades.

With STUV, vehicle manufacturers and operators can be confident that every detail — from the hinge to the lock — meets the highest safety standards and reduces lifecycle costs thanks to minimal maintenance requirements.
