The ELBE to HAYN series of early, German, steam locomotives were equipped with tenders and operated by the Leipzig–Dresden Railway Company (Leipzig-Dresdner Eisenbahn or LDE).
They were given the names ELBE, BERLIN, MULDE, MEISSEN and HAYN.
The outer firebox was equipped with a semi-circular dome that extended forward over the boiler barrel and acted as a steam collection space.
The steam cylinders were located externally, unlike those on English locomotives, which avoided the need for a cranked axle that would have been expensive and difficult to manufacture.
The steam engine was equipped with inside Borsig double valve gear driven via two eccentric cams.
