I recently booked a train ticket on South Central Railway and have the PNR number. How can I check the current status of my PNR? Are there any online platforms or mobile apps I can use to track the real-time status of my train and its arrival/departure times? Is there a specific website or service provided by South Central Railway for PNR inquiries? What information will I need to provide to check the PNR status, such as the PNR number or other details?
