Leipzig-Dresdner Eisenbahn 2-4-0 Locomotives in Germany
Class Details by Steve Llanso of Sweat House Media
Class IIb (Locobase 8010)
Data from [
] and from Christian Lindecke's Lokodex website [], both accessed 15 December 2006.
According to the Wikipedia article, Kessler delivered these locomotives in three batches over a two-year period. All had a 4-sided dome and inside motion.
Soon after they took delivery, the Saxon State Railways consortium was formed and the LDE was taken under its control. Whatever antiquated design features the Esslingen engines might have possessed, they proved durable enough to serve as late as 1913.
In 1874, the LDE bought 9 more locomotives with more "modern" boilers; see Locobase 8015.
Class IIb (Locobase 8011)
Data from [] and from Christian Lindecke's Lokodex website [], both accessed 15 December 2006.
Locobase uses the data presented by Lindecke as they more logically describe the set of locomotives described in the Wikipedia entry than do the numbers shown in the latter source. Wikipedia says these had "Crampton" boilers and inside Allan valve gear. Also, the cylinders measured an inch greater in diameter while the stroke was cut by 2".
Most of this class had been retired by the time the DRG was stood up in 1925, but two survived to receive BR 98 7301-BR 98 7302.
