Just opened up a scenic trainride at my sim Twilight Gates. It winds through mountains, meadows, forests and caves while giving you a good look at Inksy Jedburgh Designs Castles and Medieval prefabs. Search for Gothic Railway Station in SL and you will find it.
The ride is free, using one of Kitto Floras great train systems, if the train isn't at the station it's probably chugging it's way around the track, typical ride lasts 8 minutes if not stopped. See castles, pirate caves, beautiful meadows, and Gothburgh Village all along the route. Bring friends and you can all chat as you ride, sim is voice enabled.
