Update 17.09.2026 22:18
New features and improvements:
• The Activity Editor has been updated to version 1.1 and significantly optimized. Map panning and zooming are now much smoother, even for large-scale activities featuring heavy AI traffic, static consists, wait points, events, and other elements.
• Added the ability to launch the external Consist Editor directly from the consist selection menu within the Activity Editor; the list of available consists now automatically refreshes after a consist is created or modified.
• Added full integration with TSRE CZ. The Activity Editor can automatically detect TSRE CZ, launch it directly within the Consist Editor (bypassing the initial loading window), and immediately load the selected consist for editing via the "Edit" button.
• Fixed the height of dynamically generated passengers on platforms. Passengers are now positioned precisely on the actual walking surface of the platform model.
• Fixed passenger generation for AI traffic. The passenger count specified in the activity is now correctly applied to AI trains and their platforms as well.
• Fixed a bug that could cause Open Rails to crash during the dynamic generation of passengers on platforms.
Update 17.09.2026 6:50
New features and improvements:
• Added a brand-new Activity Editor (version 1.0), integrated directly into TrackViewer.
• The editor allows for the creation of complete activities from scratch, including the player's route, timetable, passengers, AI traffic, and static consists.
• Added support for managing events, wait points, speed restrictions, and power-off sections directly on the map. • Support added for loading and editing existing activities without needing the original MSTS Activity Editor.
• The Activity Editor is localized into Czech and Slovak; TrackViewer automatically uses the Windows system language upon first launch.
• Fixed a bug that could cause Open Rails to crash during the dynamic generation of passengers on platforms.
Update: September 14, 2026, 01:47
New features and improvements:
• Added horn echo effect when traveling through tunnels.
• Improved horn sound for external views outside of tunnels.
• Implemented further optimizations to improve smoothness, reduce PC load, and minimize micro-stuttering in complex activities.
• Further optimized the processing of collisions and other dynamic effects.
• Improved particle rendering and behavior under various lighting and weather conditions.
• Improved the platform passenger system and the method of automatic passenger replenishment.
• Expanded support for custom passenger models independent of specific routes.
• Passenger generation now better accounts for the current season.
• Added and clearly organized licensing information for the project and its components.
• Performed additional minor fixes and adjustments to enhance simulation stability.
Update: September 12, 2026, 01:27
New features and improvements:
• Significantly optimized the loading of activities, routes, models, textures, trains, and other simulation elements. • Optimized rendering of tracks, shadows, and precipitation to reduce PC load.
• Added dynamic passenger generation on platforms, supporting Player, AI, and Traffic trains.
• Passengers are placed according to actual platform area, with more natural positioning and orientation.
• Water and snow spray from wheels is now supported for AI and Traffic trains as well.
• Added automatic driving in Timetable mode (activated via Alt+A).
• Improved headlight greetings for oncoming trains; the greeting is now randomized.
Update 05.09.2026 15:07
• Minor performance and rendering optimizations.
• Optimized scene and cab lighting processing.
• Improved cab lighting response when changing lights.
• Fixed and optimized night texture switching and illumination.
Update 04.09.2026 01:18
New Features:
• Improved train behavior in tunnels and handling of individual train cars.
• Adjusted tunnel lighting, shadows, and smooth transitions between lighting conditions.
• Optimized loading and rendering of terrain, models, and distant trains.
• Fixed night textures and lighting effects; added support for MIRROR animations.
• Expanded vehicle lighting behavior and synchronization between the locomotive and the control car.
Fixes:
• Fixed switching between Windowed, Borderless, and Exclusive Fullscreen modes.
• Restored main menu display after ending a run in RunActivity.
