I've been booking train passage for a Spanish trip fast approaching. Half of the carriers state the electronic ticket works. Others state print at home for a paper ticket.
It has me confused. Is an e-ticket sufficient for all trains? Ouigo and Renfe. Renfe states e-tickets. Ouigo states print at home.
Do I really need a paper ticket?
I believe this falls into the "better to have it and not need it" category...
I'd follow the advice of the operator on which you book. I've taken Renfe trains loads of times with e-tickets, no problem. I've never taken Ouigo but would do what their instructions say.
