Month: 2025-11 — OpenRailAssociation/osrd delivered two key improvements plus maintenance work that strengthen planning usability and code quality. Key features delivered: (1) Operational Studies Default Stop Time Enhancement – set the default stop time for train run sections to 2 minutes, improving planning usability and accuracy. (2) Train Run Maintenance and Reliability Improvements – code cleanup removing an unused constant in osrdToNge and upgrade of the NGE package, with end-to-end test adjustments to accommodate the new version. Impact: improved operator decision support, more stable tests, and a cleaner codebase that enables faster iteration on future enhancements. Skills demonstrated: frontend development discipline, code refactoring, dependency upgrades, end-to-end testing, and cross-team collaboration with clear ownership through signed-off commits.

In August 2025, OpenRailAssociation/osrd delivered key round-trip timetable enhancements, strengthened the NGE-OSRD data flow, and implemented UI synchronization, resulting in improved data integrity, user experience, and developer productivity.

Month: 2025-07 — Focused on cleaning up the OpenRailAssociation osrd-website content and developer documentation to improve governance clarity and reduce maintenance overhead. Delivered a streamlined site with updated governance notes, copyright adjustments, removal of the cspell config, and refreshed README/CONTRIBUTING files.

June 2025 (OpenRailAssociation/osrd) delivered data-model and import robustness improvements for trainrun properties. Implemented a modular refactor of trainrun property generation by extracting path and schedule generation into a dedicated function, improving data reliability and maintainability. Extended NGE import to support forward and backward trainrun directions via a TRAINRUN_DIRECTIONS enum, with corresponding updates to path/schedule generation and labeling. Fixed labeling integrity by ensuring unique IDs for node and trainrun labels, strengthening macro editor data integrity and imported NGE data handling. These changes reduce downstream data issues, enable safer future enhancements, and demonstrate strong engineering discipline across frontend data pipelines.

May 2025 highlights for OpenRailAssociation/osrd: strengthened safety validation and localization quality through targeted test maintenance and a localization fix. Key outcomes include updated ETCS integration tests to reflect correct train behavior under speed restrictions, with refined MRSP and EoA braking curve assertions to ensure safe speed changes, and a French locale fix for the import success message to ensure accurate user-facing text. Impact: higher confidence in safety validation, improved test coverage for speed-related scenarios, and enhanced localization quality for FR users. Technologies/skills demonstrated: integration testing, test maintenance, domain logic validation for MRSP/EoA curves, and internationalization bug fixes.

April 2025 monthly summary for OpenRailAssociation/osrd: Focused on security, reliability, and user experience through targeted front-end upgrades, UI formatting improvements, and core safety logic refinements. Key outcomes include upgrading the NGE library to 2.9.23, standardizing timetable time formatting with extracted utilities for consistent minute rounding, and correcting safety speed calculation to exclude ETCS Level 2 stops with added test coverage. These changes reduce risk, improve user trust, and strengthen maintainability and future scalability.
