What if have a booked a train ticket in waitlist and there is a spelling mistake in surname
@Sanjay_laheja Usually these minor mistakes are ignored by the TTE. Unless there is major mistake like gender or major age change or name completely changed, TTE does not bother much. If they point out then you can simply explain politely that this is minor mistake while typing name and to that you will be more careful from next time.
Hope you have a pleasant journey
