I have booked a train but can not get a boarding from Borivali, however, in the schedule, it shows a stop in Borivali.
Passenger can change the Boarding station online before 24 hours of the scheduled departure of the train. In case a passenger has changed the boarding point he will lose all the rights to board the train from the original boarding point.
You can change the boarding point by following these steps :
Login to your IRCTC account and after that click on “Booking Ticket History(New)”.
You will be redirected to booked tickets page. Select the ticket for which you want to change the boarding.
Now click on “Change Boarding Point” and select the station from which you want to board the train.
