📖 About The Project

The Railway Reservation System is a console-based Java application that simulates a real railway ticket reservation platform.

It allows passengers to book tickets, manage waiting lists, cancel reservations, search using PNR numbers, generate reports, and automatically store booking records using Java Serialization.

This project is developed using Core Java only, making it ideal for demonstrating strong Java fundamentals and object-oriented programming skills.
