On the return journey of the Gotthard adventure train from Lavorgo to Erstfeld, the locomotive Ce 6/8 II # 14253 of SBB Historic, built by SLM and MFO in 1919, suffered a step switch failure between Wassen and Gurtnellen and was not able to continue the train. Ae 6/6 # 11411 "Zug" came from Erstfeld as rescue in a remarkably short time. The train is now, less then an hour late, crossing the 127 meter long and 53 meter high Chärstelenbach viaduct between Gurtnellen and Amsteg-Silenen.
