Bavarian State 0-4-6 Locomotives in Germany

Class Details by Steve Llanso of Sweat House Media

Class Phonix (Locobase 5917)

Data from Christian Lindecke's website [] (visited 28 November 2003) (translated by Google). A failure that did not rise again. The Google translation is a little sketchy on some details, but apparently the locomotive was laid out with the boiler poised over the two couple axles and the firebox supported by a tender with a frame that extended well forward.

The result rode badly and the frame proved far too weak to resist stresses that strained the boiler. Phonix was soon converted to a standard B V. It was scrapped in 1878.
