We have booked the ticket for 5th Jan 2018.As per the schedule the departure time was 23:50 from Haridwar JN. Now as the train is partially cancelled and will leave from lucknow NR at 8.30 instead of Haridwar, Do we need to get in the train on 5th Jan or 6th Jan? Please reply. Also if we cancel the ticket can we get the full refund?
