What TSW Save Game Manager is

TSW Save Game Manager is a free, open-source Windows utility for maintaining multiple save slots in Train Sim World. It watches the game’s save file and copies it whenever a change is detected. You choose the slot for incoming saves, and a stored copy can later replace the active save file through a manual restore. Each slot keeps the last 15 save files by default, with a setting to change that amount. The application supports manual savegames, not checkpoints. Notes and properties must be entered manually because the save file does not contain that metadata. The latest installer is provided as an MSI through the project’s Releases page, while the GitLab repository contains the source code. An auto-update function alerts users about new versions. The current save is highlighted and the selected slot is preserved between launches. A Windows .NET runtime is required. The project began in 2025 and its README invites donations.
