We took the high-speed AVE train from Madrid to Seville. 310 k/hr, smooth as silk, utterly quiet, large comfy seats, and with stewardesses serving drinks and snacks. Just one stop, in Cordoba. Reservations are required because these trains are always sold out.
Later, we took the same train north to Cordoba.
Madrid train station. It even has a turtle pond.
Andalusian countryside from the train. It is dry, and 90% olive orchards.
