#OnlineChart i have a major doubt on this facility can anyone help?
doubt is- so suppose if i have to book ticket in 12466 and seats are vacant then i have to take general ticket from counter and book that vacant seat with help of tt or i can just board the train and then tt will book that seat after payment for me?
