Among the first Crampton-type locomotives to run in Germany, these engines were based on the FOLKESTONE and featured a similar countershaft drive. That proved to be a weak point for the 8 Wohlert engines, the ENGLAND (ordered from Robert Stephenson), the 2 operated by the Aix-la-Chapelle-Dusseldorf-Ruhort railroad, and the 2 run by the Magdeburg and Halberstadt. Thenceforth direct-drive engines on the French model were preferred.
