Nurem-Furth 2-2-2 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class ADLER (Locobase 665)

The first engine run in Germany, the Adler was a small example of the Patentee type; cost was 1,750 pounds sterling. It went into sevice with Bavaria's Nuremburg-Furth railway on 7 December 1835.

The boiler had 62 copper tubes and valve motion was shifting eccentrics. The drivers were flangeless and the cylinders lay inside of the wooden frame. The original remained in service until 1857. See also Christian Lindecke [] (13 Dec 2003).
