The "Sputnik" is one of the smallest, but also the most famous coaches of Switzerland. From 1966 to 1969, the main workshop in Chur built 120 coaches of this type, which also had a lounge and observation post for the train crew. Later the coaches were officially designated Db. For more than 25 years, the "Sputnik" caboose was the highlight at the end of every "true" Swiss goods train. The caboose's side pulpits were crucial on the steep mountain ramps of the Gotthard and Lötschberg because they provided an optimal view of the goods train running in front, so any technical problem or apparent inconsistency could easily be discovered.
