Zeuke (Zeuke & Wegwerth, Berliner TT Bahnen, Berliner TT Bahnen Zeuke GmbH, Tillig Modellbahnen GmbH)

Werner Zeuke began making model railways in Berlin-Köpenick in the mid-1940s, initially producing 0 gauge trains. In 1947, he formed Zeuke & Wegwerth KG with Helmut Wegwerth as a fellow partner. The firm expanded from its early railway products and, in 1957, presented a complete TT system at the Leipzig Spring Fair. Its first TT models included a BR 23 steam locomotive and a V 200 diesel, alongside rolling stock and railway accessories. TT uses 1:120 scale and 12 mm track gauge.

The TT range grew during the 1960s. Zeuke moved production to a new Berlin facility in the middle of that decade, and its models reached West German customers through the Quelle mail-order catalogue. In 1972 the East German state nationalised the company, which became VEB Berliner TT-Bahnen (BTTB); production continued under that name. After German reunification, the business returned to private ownership as Berliner TT-Bahnen Zeuke GmbH. The company became insolvent in 1993, after which Hans-Jürgen Tillig took over its remaining assets and continued TT production through his firm. The Zeuke business therefore gave way to successor operations rather than ending with the 1993 insolvency.
