We caught the overnight train from Barcelona to Granada. In terms of facilities and timeliness, the train is good. However, we ran into some trouble just before boarding. From what we could gather, two of the same tickets had been printed. We were running quite close for time, and having gone through the scanner and handed over our tickets, we were stopped by a woman at the counter who started speaking rapidly in Spanish while brandishing our tickets. We were travelling in a group of seven and half of our number had already gone down the elevator towards the train. We explained that we had limited Spanish, and her response was to speak louder, faster and more aggressively. We tried to find out what was wrong or to ask if anyone could explain but noone was able to explain it to us. Eventually she got a supervisor who was friendlier but who also could not explain. She got visibly frustrated and kept waving the tickets at us and saying "duplicado". We showed her our online booking which showed seven different tickets but she just kept saying the same thing over and over again as it got closer and closer to our train's leaving time. In the end the supervisor waved us on and we got on the train just in time. They checked our tickets again on the train and there were no problems.
The service left a sour taste of what was otherwise a good train service - regularly cleaned toilets, bar cart, four person compartments made up of two comfortable bunk beds, free bottles of water, and a basin in the room.
