Prince Heinrich 2-6-2 Locomotives in Luxemburg


Class Details by Steve Llanso of Sweat House Media

Class H / BR 75 6541 / CFL 3302 (Locobase 15326)

Data from Wikipedia's entry on the PH's H, [], last accessed 26 July 2013.

The PH railway in Luxemburg, then under German rule, needed more powerful, and bi-directional, locomotives. These five Prairie tanks provided that increase and were rated at 80 km/h (50 mph). They were among the few standard gauge locomotives to be built specifically for Luxemburg service.

Independent between the two World Wars, the PH superheated the class from 1922 to 1932. The results are shown in the specifications. See Locobase 15327 for the H' of 1913, which were a big bigger and more powerful.

When the Third Reich's DRG began operating the Luxemburg system in 1942, it placed the five Hs in its BauReihe 75 654 class and dispersed them. After World War Two, three were retained by the Soviet Union in Leipzig; these were scrapped in 1946, 1949, and 1955. The two that returned to the Chemins de Fer Luxembourgeois were renumbered and retained until 1954.


Class H' / BR 75 65 / CFL 3401 (Locobase 15327)

Data from Wikipedia's entry on the PH's H', []', last accessed 26 July 2013.

As noted in Locobase 15326, the German-run PH began buying Prairie tanks in 1908 to meet a demand for more power. Five years after that quintet arrived, the PH went to a Belgian builder for ten more based on the H class, but bigger and more powerful and already fitted with superheated boilers.

The takeover of the independent Luxembourg railways by the Third Reich's DRG in 1942 led to the class's redesignation as BauReihe 75 651 and many were sent to other railways in Germany.

After World War II ended and the Chemins de Fer Luxembourgeois stood up, it could count only two of the ten initially. Four more arrived home in 1945-1946, and three more rejoined the CFL in 1950. They were placed on three principal passenger services: LuxemburgvWasserbillig , LuxemburgvTroisvierges, and PetingenvLuxemburg.

All nine remained in service until 1957, when withdrawals began. The last left service in 1959.
