Southeastern Train Crew Communication App HackaBury 2025 | Canterbury Christ Church University
🎯 The Problem Train crew members often face communication gaps during handovers, fault reporting, and service disruptions—especially when Wi-Fi or internet is unavailable. These delays and missed updates can affect safety, efficiency, and the passenger experience.
💡 The Idea Our team proposed an Android app tailored for Southeastern Railway crew members. The goal was to streamline internal reporting and handovers using simple mobile technology, even in low-connectivity environments.
What it does
The Southeastern Relay is a prototype Android app designed to improve communication between train crew members. It includes features for:
Reporting delays and faults
Completing and sharing handover checklists
Logging incidents
Sharing data offline using NFC or Bluetooth when internet is unavailable
Its goal is to make handovers smoother, reduce miscommunication, and ensure essential operational information is shared quickly and securely.
How we built it
We used MIT App Inventor, a visual programming platform that allowed us to:
Build an Android-friendly user interface
Use block-based coding to create logic for checklist forms, fault reporting, and local data saving
Add support for NFC tag writing/reading and basic Bluetooth communication
The app is still in development, but we created a working structure with screens for handovers, fault reports, and delay logs.
Challenges we ran into
Offline communication: Finding reliable ways to transfer data without Wi-Fi was tricky. We explored NFC and Bluetooth as alternatives.
Device limitations: Testing NFC and Bluetooth without having multiple devices was a major limitation.
Time constraints: We had great ideas but limited time to implement all features fully.
New tools: Some of us were using MIT App Inventor for the first time, so there was a learning curve with block programming and components.
Accomplishments that we're proud of
Turning a real-world transport issue into a working app prototype
Designing a user-friendly interface for crew members under pressure
Learning how to build mobile apps with MIT App Inventor
Thinking creatively about low-connectivity solutions like NFC handovers
Collaborating smoothly as a team and supporting each other's ideas
🛠️ My Contribution I played an active role in:
Concept development: Brainstorming key pain points in train operations
Feature design: Suggesting modules like:
Delay reporting
Fault submission
Crew handover checklists
Development: Building the app prototype in MIT App Inventor, focusing on:
User-friendly forms
NFC and Bluetooth sharing for offline handovers
Saving reports locally for upload when back online
Although the app is still in development and not yet tested in real-world conditions, it laid the foundation for a practical digital tool in transport operations.
What we learned
This project taught me:
How to apply Human-Computer Interaction (HCI) principles to transport use cases
How to design for offline-first environments
The importance of simplicity and clarity for fast-paced operational roles
Basic mobile development and block-based logic with MIT App Inventor How to design and prototype an Android app
How to think like end-users (train crew) and prioritize their needs
Basics of NFC and Bluetooth communication on mobile
That simplicity and reliability matter more than complexity in operational tools
The importance of planning features around real limitations (no internet, short handovers)
What's next for The Southeastern Relay
Finish and test the app on real Android devices
Improve the layout and logic for each reporting screen
Add data syncing options when online is available (e.g., upload to Excel or Google Sheets)
Get feedback from actual train staff or operations teams
Explore integration with Southeastern’s existing reporting tools or CRM systems
Possibly rebuild the app using Android Studio or Flutter for more flexibility
