Highest speed train brand of Renfe is called AVE (Alta Velocidad de España).
AVE connects to a many large cities in Spain.
This time, I rode AVE from Madrid-Puerta de Atocha to Málaga-María Zambrano at Trista class.
This journey takes about 3 hours with 2 stops (one is for operational stop).
The ticket costs 42.20 EUR for one way and reserved in advance.
