The NMRA published alternative, more accurate and realistic standards for track and wheels sheet in S-1.1 These model railway standards are based on the full size prototype standards and the scale model operational reliability is therefore reduced in comparison to the models conforming to the normal NMRA standards.
About 60% of the world's railways have a track gauge of 4 ft 8 + 1 ⁄ 2 in (1,435 mm) known as "standard gauge", but there are also narrow-gauge railways where the track gauge is less than standard and broad-gauge railways where the gauge is wider. In a similar manner, a scale model railway may have several track gauges in one scale.
Timesaver is a well-known [1] model railroad switching puzzle (U.K. English: shunting puzzle) created by John Allen. [2] It consists of a specific track layout, a set of initial conditions, a defined goal, and rules which must be obeyed while performing the shunting operations.
In the early 1990s, the Atlas Tool Co. changed its name to Atlas Model Railroad Company, Inc. In 1997 Atlas O, LLC was established as a separate business entity dedicated to producing multiple lines of O scale model railroad products including track, freight cars, locomotives and accessories, co-founded and led by James J. Weaver.
The standards were later published in Model Railway News by the Model Railway Study Group in August 1966. Just as in the prototype railway, on a model the wheel-rail interface is the fundamental aspect of reliable operation. So as well as a track gauge, P4 also specifies the wheel profile and track parameters to use, which are largely a scaled ...
A 242A1 locomotive and standard gauge track at some model railway scales The words scale and gauge seem at first interchangeable but their meanings are different. Scale is the model's measurement as a proportion to the original, while gauge is the measurement between the rails.

T-TRAK (all letters capitalized) is a modular model railroad system based on standards for module size, track placement, track interface, and electrical connections. The standards allow for a wide range of flexibility in design yet still maintain interoperability with all modules built per the standards.
