Data from Albert Geiseler's Dampfmaschinen und Lokomotiven website entry at [], 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.
