Client: Railway operations domain expert (Germany, Bavaria)

Timeline: Oct – Dec 2020 (2 months)

My role: UX Designer — workshops, user flows, wireframes, interactive prototype

Stack: Figma, Ant Design (as wireframe base)

Emergency passenger transport on railways is managed through fragmented manual processes and outdated software. When a train breaks down, the railway controller (EVU) must call each bus company separately to check availability, while bus drivers call back for location clarification. There's no unified system to track buses, manage replacement routes, or coordinate between the three parties involved.

I facilitated a UX workshop with the client and product team to map scenarios for all 3 user types:

↗ EVU (Railway traffic controller) — desktop app: report issues, request emergency transport, track buses, manage timetables

↗ BCO (Bus Company Owner) — mobile app: check driver availability, send offers, assign vehicles

↗ Bus Driver — mobile app (low-end devices): check issue location, confirm departures/arrivals

We defined 10 key scenarios through sketching and "note and vote" sessions, then built iterative user flows before moving to high-fidelity wireframes based on Ant Design (chosen for open-source dev compatibility).

↗ Validated user flows for all 3 personas — iterated through 2 rounds of feedback

↗ High-fidelity wireframes covering desktop + mobile contexts

↗ Interactive Figma prototype with full scenario coverage

↗ Video walkthroughs (desktop + mobile) for stakeholder presentations

The proof of concept was presented to stakeholders to support the client's funding application for full product development in Bavaria.
