Great Luxembourg 0-8-0 Locomotives in Belgium

Class Details by Steve Llanso of Sweat House Media

Class Type 23 (Locobase 20899)

Data from Albert Jacquet, "'Engerth'" Locomotives on French and Belgian Railways", Locomotive Magazine, Volume XXVIII [28] (15 June 1922), p. 174.

This was the first of two batches of "Luxembourg Engerths" supplied to the GLRy. The designs were fitted with larger grates than a typical Engerth coupled-tender. The firebox sat entirely behind and above the driving axles. A large dome sat over the first and second axles. Like most Engerths, the Crampton-type boiler included a round-topped firebox.

Locobase 20900 describes the careers of all fourteen "Luxembourg Engerths".
