Nominal size ZZ
The nominal size ZZ belongs to the class of miniature gauges among the model railroad nominal sizes (Sub-Z nominal sizes). From its appearance in 2005 until the introduction of the nominal size T in 2007, it was the smallest available nominal size in the model railway sector that is mass- produced. The standard gauge , with a prototype gauge of 1435 mm, has a model gauge of 4.8 mm and is colloquially referred to as gauge ZZ. The scale is 1: 300.
history

The tracks are made of plastic. The trains are powered by a button cell inside the head car via an axle with traction tires . There is a small switch on the roof.
