When night is falling, shortly before 6 PM, the Interregio 1157 of the Rhaetian Railway with Ge 4/4 III # 648 is pulling a yellow light trace over the 65 meter high Landwasser viaduct, landmark of the UNESCO World Heritage Albula Bernina. Sadly, the illumination of the bows of the viaduct from below is mostly defect, leaving subtle light on one bow only.
