Should I print my tickets?

It is not obligatory to print out the E-tickets sent to you by Rail Ninja in PDF format, yet you must have the ticket in any form, be it a printed E-ticket or a downloaded version of it on your phone/tablet/etc, so that you can show the ticket to the car attendant when asked. We recommend to print out the E-tickets as it is more convenient to have all necessary train information at hand. Note that in this case, it is best to have the tickets printed out beforehand as it most likely won't be possible to print out your ticket directly on European train stations.
