## Overview

This is a small Streamlit train-booking demo. A user enters passenger details, journey dates and times, travel preferences, and feedback in a form; on submission, the app displays a booking summary. The sampled source shows no booking validation, persistence, or external services. The README provides no further capability details.

Main entry points: [`app.py`](https://github.com/dinatikone123/streamlit_demo/blob/main/app.py) (Booking Summary)
