The Size of G Gauge

Why do modelers refer to HO, O, or N scales but G gauge? In all of these other scales, most trains run on a common gauge of track, but all share a common scale or proportion to the prototype. With G gauge trains, only the gauge (width of the track) is common. The scales of the trains themselves can vary from 1:20.3 to 1:32. The reason for this is due to the variances in manufacturing G gauge trains. Some manufacturers make their models a slightly larger scale so the track is more narrow in gauge in relation to the size of the model. G Gauge is among the most popular choices for narrow gauge modeling. Models scaled so that the 45mm gauge is scaled to standard gauge are also called No. 1 scale, or 1:32.

Outdoor Garden Railroads

One of the most popular uses of G gauge trains is outdoor garden railroads. The track and structures are rugged enough to survive outdoor climates all year long. Most modelers keep the trains stored inside for security and protection when not in use, though. Building a garden railroad involves very different construction methods than indoor layouts. Grading the right of way, wiring, and planting scenery all take on new meaning. There are also the problems most indoor railroaders don’t normally worry about, such as erosion and animals. For all of the added challenges, there are many advantages to garden railroading. It combines all of the joys of model trains with the hobby of gardening. For those who enjoy spending time outdoors, a garden railway is a unique home improvement and conversation piece. Of course, G gauge trains are perfectly at home inside as well.

Choosing G Gauge

If you are considering G Gauge trains for your model railroad, there are a few key points you’ll want to keep in mind. For garden railroads, it also helps to do a little more advanced research at a local home and garden center to find out which plant varieties will work best in your climate.
