If you know your PNR number then you can make yourself the ticket. Otherwise you can also make SMS of your ticket.

You can travel without e-ticket(but carrying ID is must) also only that Rs. 50 fine will be charged. Just check your name/seat in the chart and board the train. If you have an old E-ticket and you know the PNR number, stations, name of persons then simply copy the old ticket to Microsoft word and edit the contents and take a print out and save Rs. 50. Nobody checks transaction id.
