The EDWARD BURY to PFEIL series of early German locomotives were tender engines operated by the Leipzig-Dresden Railway (Leipzig-Dresdner Eisenbahn or LDE).

. They were given the names EDWARD BURY, DRACHE, ADLER and PFEIL.
The locomotives were retired between 1847 and 1854.
was rivetted from several sections. 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.
The steam cylinder was based on English construction principles and located inside under the level of the axles which meant it required an expensive and heavy cranked axle. The engine drove the second coupled axle. The steam engine was probably fitted with a simple Stephenson valve gear
without a steam expansion stage, which would not have permitted any control of steam admission.
The locomotives did not have their own braking equipment. Braking could only be achieved using a hand-operated screw brake on the tender.

Stephenson valve gear
The Stephenson valve gear or Stephenson link or shifting link is a simple design of valve gear that was widely used throughout the world for all kinds of steam engine. It is named after Robert Stephenson but was actually invented by his employees....
