Updates/Add-ons: For the most current experience, check for the Line Network Overhaul 2021, which adds plethora of events for 2024 and 2025. 2. Check Prerequisites
ALU is a freeware map but often relies on existing assets from other maps to load textures and objects:
Hamburg Day & Night: This payware add-on is frequently cited as a mandatory requirement for textures and objects.
4GB Patch: It is highly recommended to apply the 4GB Patch to your Omsi.exe to prevent memory-related crashes in high-detail areas like Laurenzbach. 3. Installation Steps
Follow these steps to ensure files are placed in the correct directories:
Backup: Create a backup of your OMSI 2 folder before starting.
Clear Old Versions: If you have an older version of ALU installed, navigate to OMSI 2\maps\ and delete the existing Ahlheim_Laurenzbach Updated folder.

Tip: When prompted, select "Overwrite everything" to ensure all updated assets are correctly applied.
Remove Chrono Events: Per the manual, you may need to navigate to OMSI 2\maps\Ahlheim_Laurenzbach Updated\chrono and remove specific old event folders to avoid conflicts with the 2021 overhaul. 4. First Launch
Load Without Buses: When starting the map for the first time, select the option "Load map without buses" in the OMSI 2 menu.
