The "chameleon crocodile" Ge 6/6 I # 415 of the Rhaetian Railway sticks its nose out of the 450-meter-long Wiesen I tunnel into the only about 10-meter-wide gorge of the Brüggentobelbach stream, which here plunges down into the Landwasser. The spot is called Bärentritt and is located between Davos Wiesen and Davos Monstein in the Zügenschlucht gorge. The locomotive pulls the nostalgia train Zügenschlucht 7822 from Filisur to Davos Platz, which runs twice a day in summer, with open observation cars as well as beautiful historic passenger cars. "Rhaetian Crocodile" or "C-C" Ge 6/6 I # 415 (built in 1929) had to be completely rewired after a cable fire. It was also rust repaired and repainted in the original brown. A special paint was sprayed over it, which will be removed after about a year (solvent-based liquid rubber in pearl / metallic effect, also called Chameleon or Flip Flop paint). The action was apparently initiated and paid for by two well-known model train manufacturers. About Chameleon sprayed paint: When moving around, chameleon paint will change colour. The light reflection on chameleon spray paint gives the multi-coloured changing special effect.
