Lnbeck-Bnchener Eisenbahn 2-6-0 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class T12/ T74 1316 (Locobase 15583)

Data from Albert Geiseler's Dampfmaschinen und Lokomotiven website entry at [link], last accessed 11 November 2013.

Among the last of the more than 1,000 T12's to be produced, this sextet had larger fireboxes and slightly smaller boilers.

Five of the Lnbeck-Bnchener-Eisenbahn locomotives were fitted with a streamliner casing in 1936. Numbered 138-142, the class retained its shrouding until 1948.
