Changing the Boarding Station
If you can't board at the reserved station, you can change it instead of canceling. Even if the ticket is transferred, the boarding station can be changed. Log in to the IRCTC website, select 'Boarding Point Change' under Transaction Type, enter PNR and train numbers, and the captcha. Tick 'Conditions' and submit. Enter the OTP sent to your registered mobile number, choose the new boarding station, and submit. Offline tickets cannot have their boarding station changed.
