A 242A1 locomotive and standard gauge track at some model railway scales. This page lists the most relevant model railway scale standards in the world. Most standards are regional, but some have followers in other parts of the world outside their native region, most notably NEM and NMRA.
A more demanding model engineering project, a propane fired 1:8 scale live steam train, running on the Finnish Railway Museum's miniature 7.25" (184 mm) track. Model live steam locomotives predominate as the most popular modelling subject in model engineering. [7] As such they deserve special mention.
Therefore, a model railroad reduces that standard to scale. An HO scale model railroad runs on track that is 1/87 of 4' 8.5", or 0.649" from rail to rail. Today model railroads are more typically referred to using the term scale instead of "gauge" in most usages. Confusion arises from indiscriminate use of "scale" and "gauge" synonymously.
In the late 1950s, Japan was known for producing low cost toys and products for export. The first brass model trains were created during the occupation of Japan by Allied forces. Members of allied forces saw some of the models built by various craftsman and procured photos of American steam locomotive prototypes for these artisans to model ...
A Japanese H0e scale model railroad One of the smallest (Z scale, 1:220) placed on the buffer bar of one of the larger (live steam, 1:8) model locomotives HO scale (1:87) model of a North American center cab switcher shown with a pencil for size Z scale (1:220) scene of a 2-6-0 steam locomotive being turned. A scratch-built Russell snow plow is ...
The burning of the fuel/air mixture in a glow-plug model engine, which requires methanol for the glow plug to work in the first place, and sometimes with the use of nitromethane for greater power output and steadier idle, occurs due to the catalytic reaction of the methanol vapor to the presence of the platinum in the filament, thus causing the ...
Some central units allow connection to a computer, and a program can then fully automatically control all model train movements and accessories. This facility is particularly useful for display layouts. Programs have been developed allowing mobile devices to be used as controllers, which also requires the central unit to be connected to a computer.
These used steel plates about 1–2 in (25.4–50.8 mm) thick. They were mainly used in Britain and continental Europe. On most locomotives, the frames would be situated within the driving wheels ("inside frames"), but some classes of an early steam locomotive and diesel shunters were constructed with "outside frames".
