Sanzin, "Die Lokomotiven auf der Intertionalen Austellung" in Mailand 1906, 29.. 5/6 gekuppelte Verbund-Guterszuglokomotive, Bauart de Glehn, der Reichsbahnen in Elsass-Lothringen ...", Zeitschrift des Oesterreichischen Ingenieur- und Architeckten-Vereines Nr. 10 (9 March 1907), p. 170-171. (Thanks to Alexander Blessing for his 7 May 2023 email noting the correct wheelbase and suppying figures for the tender capacity.) Works number were 5397-5400, 5501 in 1904; 5701-5706 in 1907; 5798-5800, 5901-5907. 5946-5955 in 1908, 5987-5993 in 1909, 6205-6212 in 1910.
This class of "decks" was the first with the wheel arrangement to enter German service. They were de Glehn compounds with Belpaire fireboxes and used larger-diameter Serve tubes that had internal fins to substantially increase heating surface area. The E-L classed them as C33 but when the Prussian State Railways took over the system a year after service entry, the class was redesignated G-8, then G-11 in 1912. They were credited with a 605-ton tonnage rating up a 1.2% grade at 20 km/h, and pulled 356 trailing tons at 40 km/h. Thirteen were rebuilt as T 19 simple-expansion 2-10-2 tank engines; see Locobase 14220. The class was not taken into the DRG.
