Data from Christian Lindecke's [] (visited 27 May 2005). See also "Chemins de fer Prince Henri" in Wikipedia at []; and "Schmalspurbahn Grundhof-Befort" in Wikipedia at [], both last accessed 1 October 2023. Works number was 1848 in 1911.
Single O&K six-coupled tank purchased for the Prinz Heinrich Eisenbahn network. The standard-gauge PHE was formed in the early 1870s to move iron ore from reserves in northern Luxemburg. Wikipedia's CF Prince Henri gives the details of its growth.
A distinctly different part of the PFE was the Grundhof-Befort narrow-gauge railway, which measured just 7 km (4.3 miles). Over so short a distance, its ascent up the Sure Valley to the higher elevations of the southern Ardennes rose 200 metres (656 ft) in a tortured path that included three hairpin turms.
These two N class engines were bespoke power for the GB grade and they served the railway until it closed after World War II.
that eventually wound up in Luxembourg after World War II as CFL 361.
