Chiemseebahn 0-4-0 Locomotives in Germany

Class Tramway (Locobase 5135)

Data (August 2002).

The Chiemseebahn was a narrow-gauge service from the Munich railway station to the port of the Chiemsee canal on the river in order to relieve roadway congestion. This little tramway locomotive (works #1813) was built to pull those 4-5 car trains and ran to a timetable.

When it first entered service, the boiler was pressed to 199.1 psi (14 bar). Compared to the 1957 upgrade shown in the specifications, the original kessel was smaller. Its grate measured 4.63 sq ft (0.43 sq m), its firebox area was 20.66 sq ft (1.92 sq m), and overall heating surface amounted to 253 sq ft (23.53 sq m). 1937 saw the replacement of the original copper firebox with a new one, also copper.

At the turn of the 21st century, the locomotive remained in service for summer use, covering 5,000 km (3,310 mi) per year over the 1.8-km (1.1-mi) track and burning 25 tons of coal.
