 This theme track calls for challenges that enable quick and effective management of construction sites and disruptions in rail traffic. We are looking for ways to guarantee operational safety, optimize information flows, and ensure the reliability of rail traffic even in unforeseen circumstances. Also sought are innovative concepts that lead to improved deployment planning, sustainable performance, and a reduction of noise and CO2 emissions.

 ### 4. Train Stations as Mobility Hubs 🏬🚉🚲
 
 This theme track seeks challenges that improve the function and experience of train stations and their surroundings. We are expecting innovative approaches for barrier-free access, smart space management, and the integration of mobility hubs to increase accessibility and comfort. Furthermore, ideas are sought that support an integrated mobility chain and offer individualized customer services at the station, establishing it as a central service location. "Station as a Service" is more than just a catchphrase here.

+- [One Screen. One Journey. Integrated Station Information incl. Rail Replacement]({{% relref "19-one-screen" %}})
+
 ### 5. Green Digitalization for Environmental Protection and Sustainability 🌳🚞💚
 
 This theme track invites the submission of challenges that address pioneering ideas and challenges in the areas of resilience, decarbonization, energy efficiency and circularity. We are looking for digital solutions that affect all areas of railway operations and logistics.

+# DIRECT – Dynamic Inspector Routing for Efficient Coverage in Trains
+
+## Problem Statement
+Quality inspections in rail operations are currently planned manually, inconsistently, and reactively. This results in inspection gaps, uneven coverage, and limited comparability across regions, fleets, and service providers.
+
+## Proposed Solution
+A standardized, data‑driven approach for dynamic routing and deployment of quality inspectors. The solution ensures that every train is inspected at least once within a defined period, under real operational constraints, with efficient resource use and consistent coverage.
+
+## Required Expert Profiles
+
+- Automated resource and workforce planning
+- Rail operations and planning (timetables, rotations, crew planning)
+- Quality management and inspection processes
+- Optimization, Operations Research, Data Science / Analytics
+- Optional: Software and prototyping expertise (e.g. Python, Jupyter, Excel-based models)

+# Holiday Aware, Data Driven Relief Train Planning
+
+## Problem Statement
+Relief trains are currently planned with limited anticipation of demand peaks caused by holidays and special travel patterns. Planning is largely reactive and relies on historical assumptions, leading to late interventions, inefficient capacity allocation, and missed opportunities to prevent overcrowding.
+
+## Proposed Solution
+A combined, data driven planning approach that integrates holiday calendars, demand patterns, and operational data with passenger flow insights derived from mobile device trajectory data. The solution enables early identification of peak demand situations and supports proactive, evidence based planning and timing of relief trains.
+
+## Required Expert Profiles
+
+- Rail operations and capacity planning
+- Demand forecasting and transport planning
+- Data analytics using mobility data (e.g. passenger counts, mobile‑trajectory‑based passenger counts)
+- Holiday, event, and seasonal demand modeling
+- Optional: Data engineering and prototyping (e.g. Python, Jupyter, dashboarding tools)

+
+## Problem Statement
+In the event of operational disruptions, relevant information is fragmented across multiple systems, channels, and formats. This leads to delayed awareness, inconsistent information levels among stakeholders, and inefficient coordination during incidents.
+
+## Proposed Solution
+A unified, role‑based incident user interface that consolidates all relevant disruption information in real time. OneUI provides fast, reliable, and context‑specific information to the right users, enabling quicker situational awareness, aligned decision‑making, and more effective incident handling.

+# One Screen. One Journey. Integrated Station Information incl. Rail Replacement
+
+## Problem Statement
+At train stations, passengers are confronted with fragmented, inconsistent, and context‑dependent information across multiple screens, signs, and channels. This becomes especially critical during disruptions, when finding rail replacement bus stops quickly and reliably is difficult, causing stress, delays, and missed connections.
+
+## Proposed Solution
+A unified, station‑level information concept that provides multimodal, journey‑centric information on a single screen or coherent set of displays. The solution integrates regular travel information with disruption scenarios, explicitly including rail replacement services as a standard use case—guiding passengers clearly from train to replacement bus within minutes.
