It so happened that I was traveling from Jaen to Barcelona, but the transfer was in Madrid. Tren was delayed, I had only 15 minutes, I did not know which way to run, the workers reluctantly answered which way to run. To change the tren, it was necessary to leave the arrival zone and enter the departure zone, which means through the control, but seeing that I was in a hurry, they quickly let me through without waiting in line.
And yes, maybe it will be useful and informative for someone, I had two small hand luggage suitcases, and this is already bad, I had to pay extra for a separate suitcase, and it does not matter that it is small. You can have one suitcase of 20 kg, but it is one. And the fact that you have two small suitcases on wheels of hand luggage, one is already considered superfluous and needs to be paid for. Thank God they let me through without paying because I was very late for the trend. I think if there was a lot of time, I would not have been missed and would have been forced to pay.
Perfectly organized space, full information, cleanliness, elevators for people with problems. The winter garden at the train station is simply admirable.
