Made by Ernst Paul Lehmann Patentwerk in Nuremberg, Germany, since 1968 [1] and by Märklin since 2007, it is the most popular garden railway model in Europe, although there are also many models of U.S. and Canadian prototypes.

The 45 mm gauge originated from 1 gauge or "gauge one" which was first used in Europe and Britain and used to model standard gauge trains in the scale of 1:32. LGB were first to adopt the term G scale and used the gauge of 45 mm (1.772 in) to model 1,000 mm gauge European trains in 1:22.5 scale.
A garden railway's scale is usually in the range of 1/32 to 1/12 (1:12), running on either 45 mm (1.772 in) or 32 mm (1.26 in) gauge track. 1/32 scale (1:32) is also called "three-eighths scale" meaning 3/8 of an inch on the model represents one foot on the real thing.

When a train is braking, the low adhesion manifests as wheel slip where the wheelset is rotating at a lower velocity (speed) than the forward speed of the train. The most extreme example of this is where the wheel stops rotating altogether (wheel slide) while the train is still moving and can result in a “ wheel flat ” caused by the softer ...
