To cross the Landwasser river, which flows from Davos into the Albula at Filisur, the engineers chose the narrowest part of the valley when building the Albula Railway around 125 years ago. The 65-metre-high and 136-metre-long viaduct made of dark limestone lies in a curve with a radius of 100 meters and a gradient of 2.0 % and leads directly into the Landwasser tunnel. Built in just 1 1/2 years in 1901/1902, the imposing structure has been a UNESCO World Heritage Albula/Bernina site since 2008. The locomotive Ge 4/4 II # 611 "Landquart" of the Rhaetian Railway, pulling freight train 5152 from Samedan to Landquart, with 1700 kW and a maximum speed of 90 km/h was delivered on June 30, 1973 as the first of its series by SLM and BBC, was green with chrome lettering and had round lower lamps on the front. With the delivery of the second series of Ge 4/4 II from 1984/85, the locomotives of the first series also gradually received the new red livery. In 2004, locomotive # 611 was the first of the series to receive rectangular lower headlights with integrated tail lights. From 2007, it was the first of the series to wear an advertising livery for Login, which was changed several times but remained in place until 2024. Now, on the initiative of the "Green and Chrome" foundation, the locomotive was more or less restored to its original condition by the RhB workshop in Landquart and presented in Landquart on april 12th, 2024. The locomotive is still in daily use on the Rhaetian Railway's main network and is also equipped with dual brakes and the new ZSI-127 train protection system.
