Wikipedia picture of the day on March 13, 2018: RhB Ge 4/4 III with a Regio Express train from St. Moritz to Chur on the Landwasser Viaduct. The locomotive carries advertisement for the UNESCO world heritage Albula and Bernina lines. The stylized viaduct pictured on the locomotive is the very same that it is currently passing over. Also note the two first coaches of a train have panoramic windows. This type of panoramic coach is normally used on the Bernina line, but because there's less traffic on that line during winter the coaches are used on other parts of the network. Wikipedia"
