and the scenery through which it passes, called a "layout". Hobbyists, called "railway modellers" or "model railroaders", may maintain models large enough to ride (see '' Live steam, Ridable miniature railway'' and '' Backyard railroad'').
Modellers may collect model trains, building a landscape for the trains to pass through. They may also operate their own railroad in miniature. For some modellers, the goal of building a layout is to eventually run it as if it were a real railroad (if the layout is based on the fancy of the builder) or as the real railroad did (if the layout is based on a prototype). If modellers choose to model a prototype, they may reproduce track-by-track reproductions of the real railroad in miniature, often using prototype track diagrams and historic maps.
Layouts vary from a circle or oval of track to realistic reproductions of real places modelled to scale. Probably the largest model landscape in the UK is in the

Operations form an important aspect of rail transport modelling with many layouts being dedicated to emulating the operational aspects of a working railway. These layouts can become extremely complex with multiple routes, movement patterns and timetabled operation. The British outline model railway of Banbury Connections is one of the world's most complicated model railways.
Model railroad clubs exist where enthusiasts meet. Clubs often display models for the public. One specialist branch concentrates on larger scales and gauges, commonly using track gauges from . Models in these scales are usually hand-built and powered by live steam, or diesel-hydraulic, and the engines are often powerful enough to haul dozens of human passengers.

Scales and gauges
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.
The size of engines depends on the scale and can vary from tall for the largest ridable live steam scales such as 1:4, down to matchbox size for the smallest: Z-scale (1:220) or T scale (1:450). A typical HO (1:87) engine is tall, and long. The most popular scales are: G scale, Gauge 1, O scale, S scale,
HO scale
HO or H0 is a rail transport modelling scale using a 1:87 scale model, scale (3.5 mm to 1 foot). It is the most popular scale of model railway in the world. The rails are spaced apart for modelling standard gauge tracks and trains in ...
(in Britain, the similar OO), TT scale, and N scale (1:160 in the United States, but 1:148 in the UK). HO and OO are the most popular. Popular narrow-gauge scales include Sn3, HOn3 and Nn3, which are the same in scale as S, HO and N except with a narrower spacing between the tracks (in these examples, a scale instead of the standard gauge).
The largest common scale is 1:8, with 1:4 sometimes used for park rides. G scale (Garden, 1:24 scale) is most popular for backyard modelling. It is easier to fit a G scale model into a garden and keep scenery proportional to the trains. Gauge 1 and Gauge 3 are also popular for gardens. O, S, HO, and N scale are more often used indoors.
At first, model railways were not to scale. Aided by trade associations such as the National Model Railroad Association (NMRA) and '' Normen Europäischer Modellbahnen'' (NEM), manufacturers and hobbyists soon arrived at ''

'' standards for interchangeability, such as gauge, but trains were only a rough approximation to the real thing. Official scales for the gauges were drawn up but not at first rigidly followed and not necessarily correctly proportioned for the gauge chosen. 0 (zero) gauge trains, for instance, operate on track too widely spaced in the United States as the scale is accepted as 1:48 whereas in Britain 0 gauge uses a ratio of 43.5:1 or 7 mm/1 foot and the gauge is near to correct. British OO standards operate on track significantly too narrow. The 4 mm/1 foot scale on a gauge corresponds to a track gauge of , (undersized). gauge corresponds to standard gauge in H0 (half-0) 3.5 mm/1 foot or 1:87.1. This arose due to British locomotives and rolling stock being smaller than those found elsewhere, leading to an increase in scale to enable H0 scale mechanisms to be used. Most commercial scales have standards that include wheel

s that are too deep, wheel treads that are too wide, and rail tracks that are too large. In H0 scale, the rail heights are codes 100, 87, 83, 70, 55, 53, and 40 -- the height in thousandths of an inch from base to railhead (so code 100 is a tenth of an inch and represents 156-pound rail).
Later, modellers became dissatisfied with inaccuracies and developed standards in which everything is correctly scaled. These are used by modellers but have not spread to mass-production because the inaccuracies and overscale properties of the commercial scales ensure reliable operation and allow for shortcuts necessary for cost control. The finescale standards include the UK's P4, and the even finer S4, which uses track

scaled from the prototype. This 4 mm:1 ft modelling uses wheels or less wide running on track with a gauge of . Check-rail and wing-rail clearances are similarly accurate.
A compromise of P4 and OO is "EM" which uses a gauge of with more generous tolerances than P4 for check clearances. It gives a better appearance than OO though pointwork is not as close to reality as P4. It suits many where time and improved appearance are important. There is a small following of finescale OO which uses the same 16.5mm gauge as OO, but with the finer scale wheels and smaller clearances as used with EM- it is essentially 'EM-minus-1.7mm.'
Modules
Many groups build modules, which are sections of layouts, and can be joined together to form a larger layout, for meetings or for special occasions. For each kind of module system, there is an interface standard, so that modules made by different participants may be connected, even if they have never been connected before. Many of these module types are listed in the Layout standards organizations section of this article.
Couplers and connectors
In addition to different scales, there are also different types of couplers for connecting cars, which are not compatible with each other.
In HO, the Americans standardized on horn-hook, or X2F couplers. Horn hook couplers have largely given way to a design known as a working knuckle coupler which was popularized by the Kadee Quality Products Co., and which has subsequently been emulated by a number of other manufactures in recent years. Working knuckle couplers are a closer approximation to the "automatic" couplers used on the prototype there and elsewhere. Also in HO, the European manufacturers have standardized, but on a coupler mount, not a coupler: many varieties of coupler can be plugged in (and out) of the NEM coupler box. None of the popular couplers has any resemblance to the prototype three-link chains generally used on the continent.
For British modellers, whose most popular scale is OO, the normal coupler is a tension-lock coupler, which, again has no pretence of replicating the usual prototype three-link chain couplers. Bachmann and more recently Hornby have begun to offer models fitted with NEM coupler pockets. This theoretically enables modellers of British railways to substitute any other NEM362 coupler, though many Bachmann models place the coupler pocket at the wrong height. A fairly common alternative is to use representations of chain couplings as found on the prototype, though these require large radius curves to be used to avoid derailments.
Other scales have similar ranges of non-compatible couplers available. In all scales couplers can be exchanged, with varying degrees of difficulty.

Weathering
''Weathering'' refers to making a model look used and exposed to weather by simulating dirt and wear on real vehicles, structures and equipment.

), sanding, breaking, and even the use of chemicals to cause corrosion. Some processes become very creative depending on the skill of the modeller. For instance several steps may be taken to create a rusting effect to ensure not only proper colouring, but also proper texture and lustre.
Weathering purchased models is common, at the least, weathering aims to reduce the plastic-like finish of scale models. The simulation of grime, rust, dirt, and wear adds realism. Some modellers simulate fuel stains on tanks, or corrosion on battery boxes. In some cases, evidence of accidents or repairs may be added, such as dents or freshly painted replacement parts, and weathered models can be nearly indistinguishable from their prototypes when photographed appropriately.

(AC). Modern Digital Command Control (DCC) systems use alternating current. Other locomotives, particularly large models can use steam. Steam and clockwork driven engines are still sought by collectors.
Clockwork
Most early models for the toy market were powered by clockwork and controlled by levers on the locomotive. Although this made control crude the models were large and robust enough that handling the controls was practical. Various manufacturers introduced slowing and stopping tracks that could trigger levers on the locomotive and allow station stops.
Electricity
;Three-rail
Early electrical models used a three-rail system with the wheels resting on a metal track with metal sleepers that conducted power and a middle rail which provided power to a skid under the locomotive. This made sense at the time as models were metal and conductive. Modern plastics were not available and insulation was a problem. In addition the notion of accurate models had yet to evolve and toy trains and track were crude tinplate. A variation on the three-rail system, Trix Twin, allowed two trains to be independently controlled on one track, before the advent of Digital Command Control.
;Two-rail
As accuracy became important some systems adopted two-rail power in which the

s were isolated from each other and the rails carried the positive and negative supply with the right rail carrying the positive potential.
;Stud contact
Other systems such as Märklin instead used fine metal studs to replace the central rail, allowing existing three-rail models to use more realistic track.
;Overhead line

The electric-outline model would be supplied by the overhead wire and the other model could be supplied by one of the running rails. The other running rail would act as a common return.

Batteries located in the model often power garden railway and larger scale systems because of the difficulty in obtaining reliable power supply through the outdoor rails. The high power consumption and current draw of large scale garden models is more easily and safely met with internal rechargeable batteries. Most large scale battery powered models use radio control.

and low temperature castings. Parts that need machining, such as wheels and couplings are purchased.
Etched kits are still popular, still accompanied by low temperature castings. These kits produce models that are not covered by the major manufacturers or in scales that are not in mass production. Laser machining techniques have extended this ability to thicker materials for scale steam and other locomotive types. Scratch builders may also make silicone rubber moulds of the parts they create, and cast them in various plastic resins (see Resin casting), or plasters. This may be done to save duplication of effort, or to sell to others. Resin "craftsman kits" are also available for a wide range of prototypes.
Control
The first clockwork (spring-drive) and live steam locomotives ran until out of power, with no way for the operator to stop and restart the locomotive or vary its speed. The advent of electric trains, which appeared commercially in the 1890s, allowed control of the speed by varying the current or voltage. As trains began to be powered by
transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer' ...
s and rectifiers more sophisticated throttles appeared, and soon trains powered by AC contained mechanisms to change direction or go into neutral gear when the operator cycled the power. Trains powered by DC can change direction by reversing polarity.
Electricity permits control by dividing the layout into isolated blocks, where trains can be slowed or stopped by lowering or cutting power to a block. Dividing a layout into blocks permits operators to run more than one train with less risk of a fast train catching and hitting a slow train. Blocks can also trigger signals or other accessories, adding realism or whimsy. Three-rail systems often insulate one of the common rails on a section of track, and use a passing train to complete the circuit and activate an accessory.
Many layout builders are choosing digital operation of their layouts rather than the more traditional DC design. Of the several competing systems, the command system offered by the majority of manufacturers in 2020 was a variant of Digital Command Control (DCC). The advantages of DCC are that track voltage is constant (usually in the range of 20 volts AC) and the command throttle sends a signal to small circuit cards, or decoders, hidden inside the piece of equipment which control several functions of an individual locomotive, including speed, direction of travel, lights, smoke and various sound effects. This allows more realistic operation in that the modeller can operate independently several locomotives on the same stretch of track. Several manufacturers also offer software that can provide computer-control of DCC layouts.
In large scales, particularly for garden railways, radio control and DCC in the garden have become popular.

Several organizations exist to set standardizations for connectibility between individual layout sections (commonly called "modules"). This is so several (or hundreds, given enough space and power) people or groups can bring together their own modules, connect them together with as little trouble as possible, and operate their trains. Despite different design and operation philosophies, different organizations have similar goals; standardized ends to facilitate connection with other modules built to the same specifications, standardized electricals, equipment, curve radii.
* ausTRAK, N Scale, two-track main with hidden third track (can be used as NTRAK's third main, as a return/continuous loop, or hidden yard/siding/on-line storage). Australian scenery and rolling stock modelled in Standard Gauge.
* FREMO a European-based organisation focusing on a single-track line, HO Scale. Also sets standards for N Scale modules. Standards are considerably more flexible in module shape than NTRAK, and has expanded over the years to accommodate several scenery variations.
* Free-mo Originally developed by the San Luis Obispo Model Railroad Club in 1995 (California), it has grown across North America and is expanding across the world. The objective of the Free-mo Standard is to provide a platform for prototype modelling in a flexible, modular environment. Free-mo modules not only provide track to operate realistic models, but also emphasize realistic, plausible scenery; realistic, reliable trackwork; and operations. Free-Mo was designed to go beyond the traditional closed-loop set-up in creating a truly universal "free-form" modular design that is operations-oriented and heavily influenced by prototype railroading. This is emphasized in the Free-mo motto, "More than Just a Standard".
* MOROP, European Union of Model Railroad and Railroad Fans, the European standardization organisation.
* NMRA, National Model Railroad Association, the largest organization devoted to the development, promotion, and enjoyment of the hobby of model railroading.
* N-orma, Polish N-scale (1:160) modules organization.
* NTRAK, standardized three-track (heavy operation) mainline with several optional branchlines. Focuses on standard gauge, but also has specifications for

. Due to its popularity, it can be found in regional variations, most notably the imperial-to-metric measurement conversions. Tends to be used more for "unattended display" than "operation".
* oNeTRAK, operationally similar to FREMO, standardises around a single-track mainline, with modules of varying sizes and shapes. Designed with the existing NTRAK spec in mind, is fully compatible with such modules.

underlayment and an interface which depends on using a metal template to locate pegs to mate to 1-inch holes in the adjoining module. The rails of the tracks are positioned in an exact relationship with the pegs. The rails come up to the end of the modules, so that the rails on adjacent modules do not need joiner track, but depend on the accuracy of the placement of the rails to allow trains to pass from one section to another. This style of module allows for very quick set-up, compared with module systems that use joiner tracks.
* sTTandard, Polish TT-scale (1:120) modules organization.
* T-TRAK, is a modular system that uses table-top modules, high, which set on tables, that are not part of the modules, but are often found at sites which members meet. It uses a specific track interface, which has joiners which hold the modules together, which enables quick setting up and taking down.
* Z-Bend Track, uses a double-track mainline running down both sides of a module. Modules can be of any length or width in the middle and any overall shape. The "standard" called Z-Bend Track applies only to the last of the module's interface to other modules, the electrical interface and the module height.
