Which app is used for booking railway tickets in Pakistan?

For booking railway tickets in Pakistan, the official and most reliable application is the Pakistan Railways Official app. This application is directly provided by Pakistan Railways, the national railway operator, ensuring that users have access to accurate schedules, real-time seat availability, and secure booking services. Using the official app guarantees that tickets are valid and recognized by the railway authority. Options B, 'Book Karu', C, 'Ticket Shop App', and D, 'Rail App', are generic names that do not represent the official booking platform for Pakistan Railways. While third-party apps might exist, the official app is always the authoritative source for such services.
