What TSW Save Game Manager is
TSW Save Game Manager is a free, open-source Windows application for maintaining multiple save slots in Train Sim World. It checks the game save file periodically and stores a copy whenever that file changes. Users choose the slot that should receive new saves, and a stored copy can later replace the active save file through manual restoration. Each slot keeps the 15 most recent save files by default, with that amount adjustable. The utility works with manual savegames, not checkpoints. Because save files do not include notes or properties, users enter those details themselves. The latest installer is provided as an MSI through the project Releases page, while the GitLab repository contains the source code. An auto-update feature notifies users about new versions. The current save is highlighted and the selected slot is preserved between launches. A Windows .NET runtime is required, and the README invites donations.
