any one can help me
Not with what you've posted so far. A "project" in IT terms usually means a specific unit of work focused on achieving a single goal (such as update invoices, add a new printer type). This definition is completely at odds with what you posted -- a railway reservation system would be an application (probably with multiple subsystems).
Furthermore, a forum like this is best for focused, specific questions. Even assuming you're wanting to know about railway reservation system applications, that is by far too vast a topic to be discussed, except in very general terms, in a forum like this.
