The Waldenburg railway is a narrow-gauge light rail system in the canton of Basel-Landschaft, Switzerland. The 13.1-kilometre long single-track line runs from Liestal, the capital of the canton, to Waldenburg, with stops in Bubendorf, Hölstein, Niederdorf, and Oberdorf. It connects to SBB train services in Liestal railway station. The line was temporarily closed between April 2021 and December 2022 for modernisation and conversion to metre gauge.
Since 2016 the line has been operated by Baselland Transport, and was, with the exception of a few industrial and funicular lines, the only line in Switzerland with a track gauge of 750 mm. It was opened on 1 November 1880 and was operated by steam-hauled trains until 1953, when electric operation began. New rolling stock was introduced from 1985.
