The origins of the Appenzeller Bahnen company lies in a number of formerly independent companies and railway lines:[1]

The Appenzellerbahn and Santisbahn merged in 1947, retaining the Appenzellerbahn (AB) identity. The St. Gallen–Gais–Appenzell-Bahn and Altstätten-Gais-Bahn merged in 1948, under the name St. Gallen–Gais–Appenzell–Altstätten-Bahn (SGA).[1]

The Appenzeller Bahnen company was formed in 1988, with the merger of the Appenzellerbahn and the St. Gallen–Gais–Appenzell–Altstätten-Bahn. In 2006, the Appenzeller Bahnen company merged with the Rorschach–Heiden-Bergbahn, the Rheineck–Walzenhausen-Bergbahn and the Trogenerbahn companies. In legal terms, this merger took the form of the Appenzeller Bahnen company acquiring the other companies.[1]


Map of Appenzell Railways lines

Today, the company operates the following railway lines:[2][3]

The St. Gallen–Gais–Appenzell, Gossau–Appenzell–Wasserauen and Altstätten–Gais lines form a connected network of 1,000 mm or 3 ft 3 38 in metre gauge lines, all electrified at 1500 V DC. Until 2018, the St. Gallen–Trogen line was also of metre gauge, but ran independently.

From 2016 to 2018, the Appenzellerbahnen undertook a large construction project to connect the Appenzell-St. Gallen and St. Gallen-Trogen lines. The three points of incompatibility were electrification (the St. Gallen-Trogen line was 1000 V DC with a brief stretch at 600 V DC shared with the St. Gallen trolleybus system), different (but physically adjacent) termini in St. Gallen, and maximal grades (the rack railway approach to St. Gallen from Appenzell was too steep for adhesion-based St. Gallen-Trogen rolling stock). So the new project re-electrified the St. Gallen-Trogen line at 1500 V DC and constructed a new tunnel through St. Gallen. The old alignment through St. Gallen closed in April 2018, and the system began through-running in October of the same year.[4][5]

The Rheineck–Walzenhausen and Rorschach–Heiden lines are geographically separate from the rest of the network, and are of respectively 1,200 mm (3 ft 11 14 in) and standard (1,435 mm or 4 ft 8 12 in) gauges. The St. Gallen–Gais–Appenzell, Altstaetten–Gais, Rheineck–Walzenhausen and Rorschach–Heiden lines all have rack railway sections, whilst the Gossau–Appenzell–Wasserauen and St. Gallen–Trogen lines are adhesion only.[2][3]

The company also operates a bus service from Teufen, on the St. Gallen–Gais–Appenzell line, to Speicher, on the St. Gallen–Trogen line. Night bus services are operated over the routes of the St. Gallen–Gais–Appenzell and St. Gallen–Trogen lines.[2]
