pandiyammal-24/Railway-Ticket-Reservation-System ? reverse-engineered prompt

Build me a Java console app for a Railway Ticket Reservation System that feels like a small real world booking tool.

It should let a user book and cancel tickets, check seat availability, view active tickets, and see booking history. When seats run out, the system should automatically move passengers into RAC and then into a waiting list, and promote people correctly when a ticket gets cancelled. I want support for multiple trains, simple passenger details, and a clean menu based flow that is easy to use from the terminal.

Please organize it with good object oriented design, use SOLID principles, and include a Singleton style booking manager. Payment should be handled through different methods like UPI, card, and cash in a way that is easy to extend later. Use Java collections sensibly for active tickets, queues for confirmed, RAC, and waiting lists, and a list for history.

Make it run in Java 17, keep the code clean and readable, and look up current Java docs online if you need to.
