I have a trip coming up where I will travel to Madrid and then take a train to Barcelona. I have 2 checked bag sized luggage and 2 carry-ons.

After doing some research, I have been told that Iryo or Renfe Ave are the best options to take. My question is, is there one better than the other when it comes to luggage allowance? Will they allow the 2 big bags on the train?
