The base game for City Transport Simulator 2026 requires 20 GB of available storage space on PC according to official developer specifications. Developed and published by ViewApp, the combined bus and tram simulator released on April 14, 2026, through Steam. Players planning to download the title need at least 20 GB of free drive space for the base setup, though additional room is required if you install downloadable expansions such as the Vienna Expansion or vehicle DLC packs.
City Transport Simulator 2026 Download Size and Storage Requirements
Both the minimum and recommended hardware specifications set the local drive requirement at 20 GB. In addition to local drive space, the game utilizes Steam Cloud functionality, which reserves up to 9.54 MB of cloud storage for remote save synchronization.
| Specification Level | Required Storage Space | Steam Cloud Allocation |
|---|---|---|
| Minimum Requirement | 20 GB available space | Up to 9.54 MB |
| Recommended Requirement | 20 GB available space | Up to 9.54 MB |
Because 20 GB reflects the uncompressed install footprint of the base game, your Steam client will download compressed files during the initial installation process before unpacking them onto your drive. Keeping extra overhead space on your drive is advisable to accommodate automatic update patches, hotfixes, and temporary extraction files.
DLC Storage and Additional Content Impact
While the core installation covers 50+ kilometers of routes and more than 80 stations in the base southern German-inspired map, ViewApp offers 14 different add-on packages that can expand your total install size. Installing major map expansions and extra vehicles will steadily increase the total amount of disk space occupied by the game folder.
Major downloadable packages available for the game include:
- Map expansions: Vienna Expansion (introduces three real-world routes, night services on line N35, and the Remise Gürtel tram depot) and the Map DLC: Depot + Southern Route.
- Tram additions: Tatra KT4D, Flexity Vienna, StadtRegioTram, E1 Vienna, GT8N Mannheim, and GT6.
- Bus additions: Citybus C2 (featuring the 12m solo bus and the 18m C2G articulated model), MAN New Lion's City, and MAN Lion's City A26 & A47.
- Bundles: Season Pass (which includes the Citybus C2K, C2 12m, C2G 18m, Tatra KT4D, Vienna Bus & Tram map, and Flexity Graz) and the Expert Edition.
If you purchase editions that package these DLCs together or plan to run the complete Season Pass roster, allocate additional drive capacity beyond the base 20 GB requirement.
