The Achensee Railway (German: Achenseebahn, pronounced [ˈaːxn̩zeːˌbaːn]] ⓘ) is a 6.78 kilometres (4.21 mi) long metre gauge railway running between Jenbach (47°23′19″N 11°46′41″E / 47.3886°N 11.7781°E / 47.3886; 11.7781 (Jenbach station)) and Seespitz (47°25′33″N 11°43′47″E / 47.4258°N 11.7298°E / 47.4258; 11.7298 (Seespitz station)) on Lake Achen in Tyrol (Austria).

Within its length it rises some 440 metres (1,444 ft) in height, with the steeper sections using the Riggenbach rack system.

Despite concerns by villagers in the area, the proposal was supported by the monastery at Fiecht, which owned the Achensee and ran steam boats on the lake.

In 1950, the Tirolean Water Company (TIWAG) acquired a majority of the shares in the railway, passing them to the villages of Achenkirch, Maurach and Eben in 1979.

[4] From 2022, the Achenseebahn Infrastruktur- und Betriebs- GmbH, founded on 2 March 2021 as the successor company, is to be in charge of operations.

The Riggenbach rack system is installed between Jenbach and Eben, from which point the line descends gently to Achensee Schiffstation.

[8] Upwards trains propel to Eben, where the engine runs round and hauls the coaches to the Achensee terminal.
