The EDWARD BURY to PFEIL series of early German locomotives were tender engines operated by the Leipzig–Dresden Railway Company (Leipzig-Dresdner Eisenbahn or LDE).
The four locomotives were delivered to the LDE in 1838 by Edward Bury and Company of Liverpool, England.
The outer firebox was furnished with a dome that projected a long way forward over the boiler barrel and acted as the steam collection space.
The two spring balance safety valves were located on the outer firebox.
Two piston pumps provided boiler feedwater; they were driven via an eccentric cam from one of the axles.
