I visited Valencia on a train from Madrid in the 80's. They worked fine then. The Roman aqueduct there is very well built and can still be used today if needed. 3 blocks up the Avenida was a nice restaurant. Ate lunch, walked around the aqueduct and took the train back. Check it out. It still looks good as new!
I visited Valencia in 1964 and 1965 as a sailor in the sixth fleet. I was paid roughly $180.00 a month and could go ashore and live it up. That was when a dollar still had some value.
