Data from "Baureihe 92 6877-6878 " in Albert Gieseler's Dampfmaschinen und Lokomotiven website at [], last accessed 22 December 2023(Thanks to Ivo Rutishauser for his 19 December 2023 email providing the correct spelling of the LBR's name.) Works numbers were 21757-21758 in 1930
This was a relatively massive tank locomotive, one of the heaviest on the rails and endowed with sizable heating surface and superheater areas. Like most Dt of their size, the two Henschels applied themselves to shunting (switiching) operating in the Luebeck and Luebeck-Moesling marshalling yards.
When one takes into account the usual German practice of measuring evaporative heating surface from the inside (fire) diameters, the tube heating surface area came to 105.3 sq m (1,029 sq ft) plus firebox heating surface area equalling 142.3 (1,133 sq ft). Locobase uses the outside (water) diameters to provide a superheater ratio with those countries that used the larger measurements.
Reclassified as BR 92 series locomotives in 1938, the pair was reassigned to Weimar-Blankenhainer and renumbered Eb 97-98 (also 92 0097-92 0098. After World War II ended, the two engines remained in East Germany and fell into the Deutchses Reichbahn's 92 6877-6878 classification.
In 1964-1965, they moved to two private operators. 6877 wound up on the Kalikombinat [Potash Combine], Werra, Sollstedt/Thüringen as their "7". 6878 in river and harbor service at the inland ports of the Oder and the harbor railway at Frankfurt an der Oder itself.
