The SBB/CFF/FFS Re 430 369-9 seen at Luzern Hauptbahnhof hauling a freight train

As we climbed from Zürich to Zug along the Zürichsee, we have parted frim the usual main line. Some long tunnels have broken our way but eventually, after following the path of our IC through Zug and Rotkreuz, we have arrived in Luzern. From there, we followed the path of the Zentralbahn to Interlaken.
