Locomotive numbers 1 to 3 on the Lübeck-Büchen railway (Lübeck-Büchener Eisenbahn or LBE) in Germany were streamlined tank locomotives. The locomotives had a 2-4-2T wheel arrangement, a two-cylinder, superheated engine and were capable of push-pull operations. In order to ensure a symmetrical running gear, both carrying axles were built as Bissel bogies, which were fitted with return devices for improved running.
