This version adds several MSTS compatibility features, such as refilling steam locomotive tenders from water troughs between the rails, support for speed limits in temporary restricted speed zones in activities, better brake functionality, improved sound handling, better handling of cab lighting in tunnels (night mode switching), and more.
There are also numerous improvements and additions to features specific to Open Rails, many persistent bugs fixed, and overall underlying improvements to the application code to allow for future development.
If you haven’t tried Open Rails, or if v1.0 wasn’t quite close enough to an MSTS replacement for running trains, it’s well worth trying out this latest version.
Note: Currently, there is an alternative route editor in independent development, but there is no replacement for the Activity Editor or other MSTS built-in editors yet. Open Rails provides an vastly improved environment to operate trains in. Creating and editing MSTS content still requires the original MSTS toolset or other third-party tools.
