A garden railroad or garden railway (Railroad in the US, railway elsewhere) is a model railway system set up outdoors in a garden. While G is the most popular scale for garden railroads, 16 mm scale has a dedicated and growing following especially in the UK. Model locomotives in this scale are often live steam scale models of British narrow gauge prototypes. 16 mm scale (which runs on ) track, the same gauge as O gauge is probably now more popular in the UK than G scale. A garden railway's scale tends to be in the range of 1/32 (Gauge 1) to 1/12 (1:12), running on either or 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. For similar reasons, 1/24 scale (1:24) is also called "half-inch scale". Other popular scales are 1:29, 1:20.3 (representing gauge prototypes on 45mm gauge), 16mm (1:19). They are smaller than the Backyard railroad, or what is commonly called a miniature railway, and would not provide a ride-on facility, being intended instead as a display railway. Smaller scales and gauges are used in the garden, but in general garden railway is used to refer to the medium scale sizes which would be impractical to use indoors. ==Function== At its most basic level, it works just like an indoor railway, including turnouts and turntables. However, special considerations must be taken for everything from sunlight and water to dirt and leaves, and even wildlife. The distance covered also means that electrical resistance in and between sections is much higher, and electrical power will tend to drop off at the far end. To eliminate this, some are rigged to use RC car parts such as rechargeable batteries. Others even use live steam and run as a real steam locomotive would. The steam can be generated from a variety of sources, ranging from messy solid pellet (i.e. methenamine) or sterno-type fuel, through clean-burning butane gas, to prototypical coal burners. Live steam is particularly widespread amongst 16mm scale garden railway enthusiasts. Many also have digital audio on board, so they sound like a real train. They can also use Digital Command Control or other similar systems, though dirty outdoor track can cause less of a problem with signal than with simple DC power. This is because DCC puts the full voltage on the rails at all times. There are many benefits of DCC when compared to DC analog systems. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「garden railway」の詳細全文を読む スポンサード リンク
