If your ticket is lost, please look into the below conditions.
If the lost ticket is an E-ticket booked through IRCTC website, you can take your ticket print as many you want by simply login to the irctc.co.in website. Once you login, go to booked history page and by using PNR number , you can take printout of your ticket.
If the ticket which you have booked is through agent/application then, you can contact the same from whom you have booked your ticket. Might be they will be able to help you if you can provide the contact number on which you got the SMS.
