Berlin & Anhalt 2-2-2 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class BEUTH (Locobase 711)

The first of many German "spinning wheels," these Borsig-built engines ran on the relatively flat North German railroads (such as the Berlin-and-Anhalt). They differed in many ways from the earlier BORSIG 4-2-2, especially in frame construction, boiler and firebox, and in the use of a single carrying axle. Later versions had horizontal cylinders and "haystack" (aka "Gothic") firebox, (1847), inside slide valves and Borsig expansion gear operating an auxiliary slide valve over the main valve.

These engines proved reliable and competent, inspiring many similar engines including the OKER (see separate entry) for the Cologne-and-Minden.
