A typical view of the Muegeln shed in the 1980s. Although these locomotives were rebuilt in the 1960s and have very few original parts left, they are still the same in principle and construction. They were first built in 1892 and still represent the technology of that time. They have two trucks and a compound steam engine (2 high and 2 low pressure cylinders) using wet steam.
At the time the picture was taken, the trains on this line did not have air brakes. Instead, they still used the original 19th century system where a rope was used to control the brakes (Heberlein brake). When the rope was taut, the brakes were loose. You can see the rope between the cab and the smokestack of the locomotive.
