Models of the BR 80
Several manufacturers of H0-gauge model railroad equipment have and still are offering models of the BR 80 with Märklin being the most prolific. Since 1988, when Märklin introduced their Deutsche Bundesbahn BR 80 (3304 and 3604) with road number 80 030, the company has offered this model in seven ever so slightly different versions. It is a nice little model with good detail and suitably delicate valve gear. The 3304 featured electronic reversing and 3604 was for digital operation. A year later they came out with the 3504, which was the same as 3304 except that it featured what is called Five-Star propulsion. You could set acceleration and top speed. In 1990, Märklin came out with Set 2866 (Junkers aircraft transport set) which included a Deutsche Reichsbahn BR 80 with road number 80 007. Set 2666 was the same as 2866 except that it was for digital operation. In 1992 the proven little Lok became 3704 but retained its DB identity and road number 80 030. The last variant was 3704, a DELTA configured version. This one was one used by the Ruhr coal company Ruhrkohle Aktien Gesellschaft (RAG) with road number D-727. From 1985 to 1992, the Märklin Primex program sold item 3190, a much simplified BR 80 with the road number 80 031. This Lok was also part of passenger train set 2750 but, in that case, the road number was changed to 80 030 and the engine was painted silver. I can't offer any explanation for that. Märklin did not offer an DC versions of these Loks.
Roco in Austria sold a DC version and this one carried the number 80 028 in the early 1980s and another detailed version with the numbers 80 018 in 1996 only. In addition, Roco offered what might be called a Junior model, a less detailed version. Trix has a BR 80 albeit a rather simplified one.
