I was fortunate to spend 10 days in Italy at the end of June and a few days in July. We took trains between the towns along the Cinque Terre, a train from Florence to Naples, and a train from Naples to Sorrento. The train from Florence got up to 189 miles per hour (displayed as close to 300 km/hr) according to the information screen in our car.
I like to build structures so I have thoughts about doing a scene with a station on my base level with buildings lined along very narrow streets terraced on steep hill sides, extending above and below track level several feet. Tile roofs, brilliant colored stucco, green shutters, dinner tables streetside, and even wooden fishing boats lining one road (Manarola, Italy) extending under the tracks angling down to the lower part of the town and eventually seaside. Nice to dream. Lol. But what loco to run?
