OpenTTD 16.0 reaches release candidate with font and rail pathfinding fixes

OpenTTD 16.0-RC1 marks the transition from feature development to stabilization for the upcoming major release of the open-source transport tycoon simulation. This release candidate includes four specific fixes over the previous beta5: an update to the bundled OpenTTD TTF fonts to version 0.9, corrected rail station coverage area highlighting behavior, a resolved edge case where trains could experience path reservation failures or crashes after uncommanded movement following end-of-line reversals, and a fix for uneven autoroad construction hotspot detection.

The project is now soliciting broader community testing to surface remaining issues before the final 16.0 release. Players are directed to the project's issue tracker for bug reports. The changelog contains the complete list of changes since the prior beta.

What changed in OpenTTD 16.0-RC1

• Font subsystem: Bundled OpenTTD TTF fonts updated to version 0.9, affecting text rendering across the UI.
• Rail station coverage UI: Fixed inconsistent highlighting behavior when displaying the coverage area of rail stations, improving visual feedback for station placement planning.
• Train pathfinding and safety: Resolved a bug where an uncommanded movement step after end-of-line reversal could corrupt path reservations or cause train collisions, addressing a stability and simulation correctness issue.
• Road construction UX: Fixed uneven hotspot detection for autoroad placement, making road building more predictable during player interaction.

Why it matters

OpenTTD remains one of the most prominent open-source game preservation projects, maintaining and extending a classic transport simulation without proprietary dependencies. The 16.0 release cycle demonstrates sustained volunteer-driven maintenance of a mature C++ codebase, offering a model for long-term open-source game stewardship. For Linux distributions and Steam Deck users, the release candidate provides a stable target for packaging and testing ahead of the final version.
