Re 620 # 077 (Re 6/6 # 11677) "Neuhausen am Rheinfall) and Re 420 # 247 (Re 4/4 II # 11247) of the SBB in multiple control (common called as Re 10/10) are pulling the Holcim gravel train 67787 from Hüntwangen via Bülach-Regensdorf-Brugg-Rotkreuz-Erstfeld-Gotthard mountain line to Bodio, over the 150 meter long Reuss bridge between Oberrüti and Rotkreuz. The river Reuss has an extraordinary amount of water (approx 400 m3/second), near the maximum that can/should be discharged in a controlled manner from Lake Lucerne (Vierwaldstättersee), which is in high flood after the heavy rains of the previous week.
