There’s a train line from Naples to Sorrento and around the famous volcano Mount Vesuvius that’s called the ‘Circumvesuviana’ Line. The trains are rickety but inexpensive and efficient. I’m sure that many people might decry the graffitized cars (and stations, for that matter), but I like the riot of colour. The best artists add a lot of vibrancy to what are otherwise dull places. As I was going to Herculaneum with a small group, we were entertained on the train by a trio of Syrian Christian refugees (father, son, mother). The boy had a drum and was excellent. It was a great day.
