O scale
O scale is a scale commonly used for toy trains and model railroading. Originally introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s...

, to describe a "compromise" form of modelling that strives for realism while accepting the compromises in scale associated with toy train
Toy train
A toy train is a toy that represents a train. It is distinguished from a model train by an emphasis on low cost and durability, rather than scale modeling. A toy train can be as simple as a pull toy that does not even run on track, or it might be operated by clockwork or a battery...

 toy train track sits much higher than finescale track.

The compromises that were traditionally made in manufacturing these trains have led to three approaches to model railroading in these two scales.

The traditional toy train layout makes little, if any, effort at realism and often makes use of unpainted plastic

 brand, and other toys, making little or no effort to disguise their origin. In some cases, the buildings, vehicles, and figures on the layout may not even be the same scale as the train, or each other. Roads, grass, and roadbed may be painted onto the table surface, or may be represented with low-pile carpet.

Scale modeling also occurs in O and S scales, just like in HO
HO scale
HO or H0 is the most popular scale of model railway in the world.According to the NMRA standard S-1.2 predominantly used in North America, in HO scale, represents 1 real foot ; this ratio works out to about 1:87.1. According to the MOROP standard NEM 010 predominantly used in Europe, the scale is...

N scale
N scale is a popular model railway scale/track gauge. Depending upon the manufacturer , the scale ranges from 1:148 to 1:160. In all cases, the gauge is . The term N gauge refers to the track dimensions, but in the UK in particular N gauge refers to a 1:148 scale with track gauge modelling...

 scales, where the modeler tries to create a miniature world that is as realistic as possible. Scale modelers in O and S scales will often avoid, or at least make limited use of, traditional American Flyer and Lionel locomotives and rolling stock since it sometimes was not very true to scale, was lacking in detail, and used oversized knuckle couplers. Scale modelers use O gauge track, but with two rails rather than the three rails used by Lionel, and the trains run on direct current
Direct current
Direct current is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also flow through...

. Numerous standards for track that is more true to scale exist for both O and S scales.

High rail is an in-between approach. High-railers live with the out-of-scale track and will make use of off-the-shelf diecast vehicles that may be slightly out of scale, especially in O scale because true 1:48 scale vehicles are scarce, whereas 1:43 and 1:50 scale diecast vehicles are very common. Some use vintage Lionel and American Flyer trains, while others opt to use modern equivalents built to greater detail. High railers often will repaint and weather their trains, vehicles, and buildings, just as a scale model railroader would. Sometimes they will go to great lengths to try to conceal the middle rail on Lionel track, and will replace the oversized couplers that came with their trains from the factory with scale versions. High railers are less likely to engage in scratch building

Kitbashing

and super-detailing their buildings and structures.

Some manufacturers, particularly in S scale, will offer rolling stock with either scale or high-rail trucks and couplers, in order to cater to all potential markets.
