Locomotive No.18 'Gündlischwand' rolls into Breitlauenen to cross an uphill train, and to pick up a couple of passengers. SPB trains generally run with the pantograph lowered in the downhill direction. No.18 was built for the Wengernalp Railway in 1910, where it worked until 1964 when it was transferred to SPB.
