A “G scale neck,” referring to model trains, specifies the gauge, or track width, in relation to the size of rolling stock. In this context, “G scale” designates a large-scale model railway with a gauge typically around 45 mm (1.772 inches), allowing for significantly larger model trains than HO or N scales. The term is often used when discussing the parameters and compatibility of model train equipment.
The advantage of using “G scale” is the ability to create highly detailed models visible from a distance, often employed in garden railways. Its robustness makes it suitable for outdoor layouts, withstanding various weather conditions better than smaller scales. Historically, “G scale” has provided enthusiasts with an accessible entry point into model railroading due to its relatively larger size and ease of handling.
