: Originally designed as a training tool, it accurately simulates complex German railway operations, including various train protection systems like PZB , LZB , and ETCS . Scale and Content :

The base simulation includes over of drivable routes, such as Cologne–Düsseldorf (exclusive to the Aerosoft Edition) and the ICE route Kassel-Göttingen.

It features more than and hundreds of passenger and freight cars.

The simulation is built on a modular system that allows for extensive user expansion. ZUSI 3 - Aerosoft Edition - Just Trains

Zusi 3 is distinguished from other train simulators by its extreme focus on and prototypical accuracy rather than visual flair.

: It simulates realistic driving and braking physics, accounting for tilt, air resistance, and curve resistance. It also includes ZusiDisplay , an integrated application that replicates real locomotive cockpit displays. Core Simulation Features
