Eversholt Rail is one of the UK's major rolling stock owners, they own and maintain fleets that move millions of passengers every day. Change requests against those fleets had grown up across email threads, spreadsheets, and bespoke trackers. The work was getting done. The audit position was getting harder. They needed a single portal where engineers, fleet teams, and external partners could raise, assess, approve and track change requests against fleets, units, and components, with the kind of audit trail a regulated operator needs. 300 Train units covered 3 months Delivery window 2 Engineers on the build ## OnTrack, a change request portal on OutSystems. **Flexible change request engine.** Configurable by type, scope and priority. Custom workflows route requests to the right people without reconfiguring the platform. **Fleet & asset metadata layer.** Fleets, units, competencies, roles, and engineers all modelled and connected, so a change request knows what it's actually changing. **SSO and granular permissions.** Identity tied to the existing estate. Access tightly scoped per role and per fleet. **Approval chain with rationale.** Every decision captured with the person, the time, and the reasoning, defensible under regulatory review. **Reporting dashboards.** Fleet insights, asset tracking, embodiment status, surfaced cleanly for both technical and business audiences. **Internal teams + external partners.** Designed to host engineers from across the partner network without compromising on access control. ## Faster change delivery, defensible audit posture. OnTrack runs as the single record of change across the relevant fleets. The team get faster cycles and full visibility. The regulator gets a clean audit record on demand. The platform is designed for ongoing evolution, new fleets, new partners, new change types, without re-engineering. PortalChange managementOutSystemsRegulated More work ## Other things we've shipped.
