In Germany, either in autumn or in spring, there is a very large model railroad exhibition organized by three model railway clubs. The clubs are building their modules in the FREMO standard, very similar to those HO scale modular standards which a recommended by the National Model Railroad Association in the United States.
These are unique standards in module construction, DCC wiring, track and scenery. The model railroad modules used in this exhibition contain more than 200 meters of railway tracks. There are more than 100 model trains in DCC mode an the famous, self-controlled model cars. A very special feature of several modules are the frivolous and sexy scenery, for example, the love couple near the nudist beach. This love couple, moving automatically, is one of the famous products made by Viessmann company in 1/87 scale.
