About Zusi 3: Aerosoft Edition
Zusi 3: Aerosoft Edition is a PC train simulation in which you operate trains from the driver's cab. It recreates railway operations with authentic driving and braking behaviour, prototypical signalling and timetables, and train protection systems including PZB and LZB. The professional version of Zusi 3 is also used by railway companies to train engine drivers.
Routes and timetables
The game includes 10 routes from different eras, including Cologne–Düsseldorf, developed for the Aerosoft Edition. Together they provide more than 500 kilometres of track. You drive according to predefined timetables, where hundreds of trains can operate at once and affect one another; an autopilot controls every train except yours. You can preview each train, with an overview of its timetable and vehicles.
Tracks are built in modules that can be combined into larger networks within a timetable scenario. The game also supports interfaces for geodata to help create realistic, precise tracks.
Driving and systems
You control vehicles with a keyboard and mouse or driver’s desk hardware. Adjustable assistance lets beginners and experienced players set the protection systems less strictly to make learning easier. Driving and braking dynamics account for tilt, air resistance and curve resistance, and the simulation covers various drive types and brake systems.
The train protection systems include:
- Indusi I54 and I60, I60R, PZB60 (ÖBB), PZB90 1.5 and 2.0, PZ80 and PR80R
- LZB/I80 with and without PZB90, CIR-ELKE, and LZB with complete and divided block control
- GNT/ZUB122 and 262 with tilting technique
- ETCS (European Train Control System)
The simulation also includes various Sifa systems, door protection systems and surround sound. Its signalling follows the original systems and includes all German signal systems. Track routes are reproduced with precise alignment, including superelevation at points.
Editors and expansions
You can extend the simulation with additional routes, vehicles, timetables and other content. The included editors let you create your own timetable scenarios, vehicles and tracks, as well as other additions to Zusi, and share them with the community.
