Open Rails Project

The Open Rails Project is a volunteer-driven initiative dedicated to preserving and extending the legacy of Microsoft Train Simulator by delivering an open-source railroad simulation platform. Built from the ground up to support the original MSTS content while eliminating the constraints of aging 16-bit code, Open Rails provides enthusiasts and route builders with a 64-bit simulation engine that runs on modern Windows systems and leverages contemporary graphics capabilities. Typical use cases include prototypical operation of both historic steam and modern high-speed passenger consists, accurate timetable running, realistic signalling and dispatching practice, and detailed cab-crew training scenarios. The software accepts existing rolling-stock and route files, yet adds multi-core CPU support, higher frame rates, more precise physics modelling, dynamic braking, advanced adhesion logic, and open data formats that encourage community extensions. Users can create or share activities, timetables, and environments through compatible editors, while content creators benefit from transparent file structures and active wiki documentation. Open Rails is available for free on get.nero.com, where the latest build is delivered through a trusted Windows package source such as winget and can be installed individually or alongside other applications in a single batch operation.
