The narrow-gauge trains in Appenzell set it apart. The picture windows can be opened so you can lean out as you career over green hills and sniff wildflowers and fresh-cut grass. At St. Gallen, the main hub for regional trains, you can transfer to the Gossau–Appenzell–Wasserauen line. To see more of the territory, you may return to St. Gallen by way of Herisau. The Swiss Travel Pass includes St. Gallen and Schaffhausen city transit, as well as overall rail privileges throughout Switzerland.
