An online railway ticket booking system in ASP.NET is a web-based application that allows users to book train tickets through the internet. The system can be developed using the ASP.NET framework and can include features such as search for trains, seat availability, fare calculation, booking, and payment. Users can also check their booking status and cancel tickets if needed. The system can be integrated with the railway’s database to provide real-time information to the users. It should also have a user-friendly interface and be secure to protect sensitive information such as payment details.

Programming languages:

• Front End: ASP.NET
