The railway administration reserves seats, berths and compartments in accordance with the rules and conditions published in the coaching tariff, said IRCTC (Indian Railway Catering and Tourism Corporation) on its official website- irctc.co.in.
A passenger seeking reservation of berth or seats can purchase tickets either from the railway reservation offices/authorised travel agency or may buy an online ticket via IRCTC's official website or mobile app.
Passengers booking a ticket are assigned a specific status which can be waiting (WL), RAC (Reservation Against Cancellation), or confirmed (full berth).
