Just got married! Maiden name on passport, Married name on ticket...

I just purchased tickets and by mistake I used my new married name on the train ticket. My maiden name is on my passport and I have booked all other trip tickets in my maiden name (did not have time to have my passport changed to match my new married name).

Do I need to have my ticket changed to match my passport name or will the ticket name matter? And if I need to have it changed how do I do that? The ticket option we have is a "print at the station E-Ticket"
Thanks for any help.
