Railway model

Railway model(Tetsudo Mokei) is a certainScale-GaugebyRailway car-line OfmodelSay


From objects that are sized to be pinched with your fingertips to objects that are a fraction of the actual size and can be towed and straddled by a passenger trolley, general train models that operate like the real thing and the surrounding scenes It is called a "model train".Of course, besides the size, there are also differences between the actual railway and the model railroad.For example, the difference from the actual railway line is that while the curves of many tracks in the model railroad are monocentric curves, in the actual railway lines, transition curves are often inserted before and after the curve.[1]..In addition, in the case of train models, there are differences in the power supply method.

Initially it was an expensive hobby, but as it becomes more popular, small-sized models tend to become more popular, reflecting the housing situation of the common people.Long time agoTinplateMade oftoyAlthough the boundary with was ambiguous, the vehicle and gauge were gradually determined by the scale and gauge.Layout-DioramaThe standard for collecting and running on the railroad tracks to enjoy the scenery of the railroad has come to be set.

A product that is manufactured in 1/3 the size of a real railway at amusement facilities and can be used inside a passenger car (UK:Romney Hythe & Dim Church Railroad, Japan: Shuzenji, IzuRainbow Town) And full-scale prototype mockups of railway vehicles are also models, but these are not generally called railway models.Also,Plastic modelTrain models that cannot run, such as railroad models and figurines, are also distinguished from model railroads.

Unlike other types of models, the special feature of model railroads is that they arelineBecause it is a thing that runs on, it is with a vehicleGaugeIs always paired.ScaleThe size varies depending on the type, but it is summarized to a certain number of scales.This is to make it possible to use ready-made products by setting standards on a scale.

"Scientific pictorial"How to make a model electric locomotive" was written by Ken Kasai on 1/30.35mm gaugeIs adopted. The electric locomotive of this standard won the highest award at the 1927st Model Country Exhibition hosted by Children's Science held at Nihonbashi Mitsukoshi in 1, and attracted attention.Railroad (magazine)』Promoted this gauge[4]..Manufacturers have come to follow suit and release products[16], 35mm gauge became the mainstream of Japanese model railroad standard before the war.A model club called Mitoikai (played 35) was founded, and the venue was rented for frequent public driving.News movieWas taken up by[17].. on the other handO gaugeSome enthusiasts enjoyed producing the 32mm gauge of origin at a scale of 1 / 40-1 / 42, and the finished product was also on sale from Chiyoda Keiki Kosakusho. 1938 "Model Railroad"[Annotation 7]Ichiro Yuyama in the magazine[Annotation 8]Announced "Standard Gauge of Model Railway".In this article, if you use an O gauge with a gauge of 35 mm compared to the 32 mm gauge that goes on a road unique to Japan, you can run on the same track for the American type, British type, and Japanese type (although the scale is adjusted).[Annotation 9]He explained the advantages of the O gauge and recommended 1/45 for the Japanese scale.However, the backlash from 35mm gauge advocates created a conflict between the two, which continued until Japan lost World War II.[18][Annotation 10]..

For model railroads, scales, gauges, and electric ones電流-VoltageThere are various standards such as, and they are commercialized based on those standards.Also, if you make your own, it is often made to meet those standards.

The standard of the model railroad is the manufacturer and the group of lovers of the model railroad (NMRA,MOROPSince it is decided by (etc.), there are differences depending on the country / region, manufacturer, etc., and although there is commonality, they are not completely the same.The standards of each region are generally the same except for the difference between the metric system and the imperial system, but the names and scales may differ from each other.In this paper, we mainly use the names, gauges, and scales that are commonly used in Japan.

The name of the standard is called gauge in Japan and the United Kingdom, and scale in the United States (NMRA standard, etc.).

As a general rule, each standard is realStandard gaugeIt is a reduced gauge of 1435 mm (standard gauge model).In addition, there are narrow gauges that reproduce narrow gauges narrower than standard gauges and broad gauges that reproduce wide gauges.

Initially, it was represented by the distance between the centers of the two rails that make up the railroad track, but now it represents the distance inside the head of the rail.

If you shrink the real thing, you can decide the gauge as you like, but in reality there are a certain numberGaugeIs aggregated in.

Standard gauge and narrow gauge / broad gauge

As a general rule, the standard gauge of the model is the one that is reduced based on the actual standard gauge (1435 mm).Although many narrow gauges are found in the actual products in Japan and South Africa, the models on the market often have standard gauge specifications.In Finland and Ireland, the actual product has a broad gauge, but the models on the market often have standard gauge specifications.

  • Narrow gauge: A general term for standards that model the actual narrow gauge railway (narrow gauge).There are relatively many railroad tracks and vehicles on the market.
  • Broad gauge: A general term for standards that model the actual broad gauge railway (broad gauge).There are only a few railroad tracks and vehicles on the market, and very few enthusiasts adopt it.In addition, the European NEM standard treats broad gauges up to 1700 mm as the same standard as standard gauge.
  • Narrow gauge and broad gauge standard notation
In European style, "XXm","twentieth","XXi (XXf)","XXp".The correspondence between these names and the actual gauge is as shown in the table below, and there is no one-to-one correspondence with the actual gauge.

Course and fine

Meaning "coarse".Since the model railroad was developed from toys, it was one of the indispensable conditions that it was difficult to derail.Therefore, it is expensive compared to the real thingFlangeWith thick tiresTurnoutNeeded a flog with a wide flange way. Since the "course" is not a toy, but emphasizes running performance (practicality), it often becomes the standard for model railroads.
Meaning "fine".After that, some people wanted a "fine" model.A group of models made of wheels and railroad tracks, especially points, as if they were made smaller, is called a fine gauge.A term used in all scale and gauge model railroads.Although it involves precision work, it often comes at the expense of driving performance in lightweight model railroads.It may include work to bring the gauge that is too wide closer to the scale.O gaugeIn the above, groups such as Proto48 are active.HO gaugeThe following is quite difficult, but groups such as Proto87 are studying.

Toy train tin plate

In one field of model railroad,Scale modelIs a term for.Many of the early model railroads were of this type, especially in the United States.Originally a high-class model, around 1936, when the era of mass consumption for Christmas gifts arrived.LionelAfter presenting a system that could be developed, it was popularized as an American standard model at once.Literally "tin plate" is a term that refers to a tin plate model railroad and is synonymous with the word hi-rail.It is a toy model railroad that uses tall hollow rails, and is designed to run high-flange vehicles, and the central three-wire current collection method is the mainstream.Recognized as a hobby not only for young people but also for adults, a large-scale exchange meeting and swap meet will be held for several days.

In the case of O gauge, the scale is about 1/64 to 1/48, but it is not constant.If you make it small, even a large machine can run with a small radius, so some products have a scale of 1/58.Although the tin plate has many O gauges,American flyerThen there is also an S gauge.This has adopted a two-wire system from the beginning.

Similar products in Europe and Japan are sometimes called toy trains or tin plates.In Japan, O gauge and 16 gaugeShortened type (shorty)The product is considered to be applicable.

AC method

Märklin,LionelThe central three-wire system is adopted, but the AC system does not necessarily mean that it is a three-wire system, and although it is a small number, it is an AC two-wire system or a DC three-wire system (described later). There is also a model railroad.1930 eraIs efficientrectifierAnd powerfulpermanent magnet For consumerIt wasn't on the market, soSeries winding motorelectromagnetThe combination with the direction change device (reversing machine) was adopted.InsulationWheelIt is still very popular because you don't have to use.

With the progress of electronics, the number of users who prefer the multiple control method (described later) has increased.Alternating currentThat saidSine waveThe number of AC-driven models that are not is increasing.

DC method

To get direct currentStorage batteryOr smallrectifierNeeded.automotive industryIn the developed United States,Selenium rectifierHas begun to be marketed for consumer use, so the standard "DC 12 V" was established by diverting this.Normally, a DC two-wire system that collects electricity only from the left and right rails is used, but there are a few DC three-wire model railroad models.TricksThen, there is a DC three-wire system "Trix Express" as opposed to a DC two-wire system "Trix International".

In the DC two-wire system, there are many products that move forward mainly when positive electricity is flowing through the rail on the right side when viewed from the vehicle.[30].

The advantage of the DC method was that it was possible to freely choose forward and backward without a mechanical reversing device.AC methodSeries winding motor OfFieldIf the magnetic field was set to a unidirectional magnetic field with an in-vehicle rectifier (this is called Polarized), the direction of travel could be switched with a single switch at hand.Second World WarLater Thepermanent magnet OfFieldAnd this isSequel motorAlthough it is not the most suitable type of motor for driving model vehicles, it has become widely used.

  • Series winding motorAt the start of the motor vehicle電流In proportion to the square oftorqueIs generated, it is easy to reproduce the actual departure (starting) situation, the current value decreases when cruising, the rotation drops on the uphill, the current value rises, and the traction force increases.On the other hand, with a permanent magnetFieldIn the motor with, the magnetArmatureBy sucking, even if you turn the wheelgearBecause the motor does not rotate through, the actual railroad vehicleCoastingI can't reproduce how I do[Annotation 16].

In the current most advanced drive system, the rotation speed of the motor is driven by an acceleration / deceleration curve that imitates the real thing by electronic control, and Bemf (back electromotive force) is measured to keep the rotation speed constant.Also, it is not attracted to permanent magnets.Ironless core type motor (coreless motor)AdoptReverse drive worm gearPush and move in combination with (Free-rolling mechanism ) Motor vehicles have been put into practical use.

The voltage of 12 V is as mentioned above.automotive industryIt was a standard derived from, but when the track becomes longElectric resistanceCan no longer be ignored, and there is a debate about increasing the voltage, which can reduce the current value and reduce the voltage drop.1980 eraIt started in. There was also a move to boost to 24 V, but with the adoption of an efficient motor, that voice disappeared.O gauge,G gaugeThen.LayoutDue to the large scale of the 12 V car, 16-18 V may be adopted in some cases.

Multiple control method

It is a general term for a method of individually controlling a plurality of vehicles on the same track.Not only driving a vehiclehorn,Headlight-taillightBlinking of is also included in this concept.1960 eraFrom around that time, direct current was mixed with alternating current and flowed.frequencyAs a method of identifying byGeneral ElectricAstrack (Automatic Simultaneous Train Controls ,ASTRAC), And although there was a method of flowing alternating current and direct current at the same time,analogThe method was limited to controlling several units at most.There was also a Märklin delta system that used three-wire tracks.デ ジ タ ルIn the formulaHornbyThere were ZERO-1 of Märklin and Märklin Digital of Märklin.There was also a digital type called CTC-16.Both are dedicateddecoderIt was not possible to run on the same track as a conventional vehicle except for some parts.

2000 eraLaterDigital command control(DCC) has become a global standard, and vehicles equipped with connectors that are presumed to be equipped with DCC are becoming widespread in Europe and the United States. In theory, DCC can issue commands to 10 units at the same time when the address length is 1024 bits.

Drive system

When the model railroad appeared, it was designed to be pushed by hand.With the progress of the times, it became possible to drive the royal fern and run on its own by steam, and finally it became possible to control it from the outside by electricity.

It was an evolution to a smaller electric model that could be enjoyed indoors, rather than steam-driven, which had to be left unattended when humans had to ride and control it or start moving.Of course steam driveLive steamAlthough it has evolved specially as a model, the electric model has moved to a smaller size.

Wind-up drive

In the early model railroadMainspringThere was a power thing of the formula.They were called spring motors.It is still used in some tin railroad toys.

Method using steam engine

Initially, there were many things that combined a simple boiler and a single-acting oscillating engine, and once they started running, they continued to run until they ran out of water or fuel.In the meantime, a model that had a structure exactly the same as the real thing and was driven by a vehicle carrying a human became the mainstream.This is the same as the real thing in water supply, bonfire, operation, turbine generator andInjectorSomething to equip has appeared.In addition, a model has also appeared in which an articulated locomotive put into practical use in the United States is connected by the same ball joint air supply / exhaust pipe as the actual one.In addition, a model that uses a steam turbine to generate electricity and runs on an electric motor has also been prototyped.

It was temporarily obsolete due to the spread of electric models that can be easily driven, but the hurdles for realization are lower than before due to the entry of some enthusiastic enthusiasts and new manufacturers supported by them from the mid-1970s. It has become to.In addition, driving events have been held in various places where enthusiasts gather.

In addition,MärklinExisting manufacturers such as are also releasing new products.Advances in electronics have made it possible to radio control small models.1 gaugeThen many people have come to enjoy it. In the 2000sHornbyからOO gaugeThe electric steam locomotive was released, and the finished product that can control the whistle from the outside was also released.They areLive steamCalled,Garden railwayIt is enjoyed as one of the fields.

Method using an electric motor

The electric model started at the same time as the power distribution to the home.At the timePower InputIs because the performance was low for the high price.Alternating currentIn some areas before the start of power distribution to homesDCIt was distributed at.

Electrification was realized by adding a third rail for current collection to the steam engine or spring-type two-wire track that was initially adopted.To adopt the two-wire systemWheels and axlesTheInsulationSince I had to do it, I had to modify the vehicles that I had sold so far, but if I learned from the real thing and collected electricity from the third rail in the center, there would be no inconsistency with the previous products.In Japan, there was no real central three-line railway, so this type of current collection method was disliked as a toy, but in Europe and the United States, it was accepted as being the same as the real one.

at firstSeries winding motorMade by myselfTransformerorResistorWas controlled by.Some resistors used saline solution.SmallmotorAfter it was released as a model, the size of the motor vehicle that houses the motor was decided.In other words, the miniaturization of the model size was also the history of the miniaturization of the motor size.FieldMove the coil to the extension of the shaft, make a double-axis motor and make an axleTrolleyThe ingenuity at this time is remarkable.

The field iselectromagnetThe series-wound motor rotates with both AC and DC, just like the real thing.Locomotive,Electric trainIt had characteristics suitable for driving.At startup電流Starts in proportion to the square oftorqueIs generated, and the current decreases at the same time as the rotation increases.speedGradually according toVoltageIf you raise the value, you will be able to drive realistically.However, in order to reverse the direction of travel, the polarity of the field had to be reversed.Lionel,MärklinEt al. Operate by momentarily interrupting the currentrelayEtc. were developed and put on the market.HoweverTurnoutMay malfunction when passing through, due to the rotation of the motorCentrifugal forceA malfunction prevention device using the above has been developed by some enthusiasts.

1930 eraAt that time, an attempt to drive DC began.In some areas it was distributed by direct current, but in most areas it was distributed by alternating current.The United States of AmericaThen.motorizationByAutomobileSmall forrectifierWas released for consumer use, and the field current was changed.Selenium rectifierIt was devised to rectify with and reverse the polarity of the traveling current to reverse it.In addition, 12 V for automobiles was adopted as the standard voltage.

1940 eraTo become andpermanent magnetWas made into a fieldMagnet motorIs now on the market.It's small and lightweightpower consumptionThere were few, butMinute winding characteristicsIt was a thing that had a given voltage and the number of revolutions was directly proportional.Then, control by voltage control by electronic components is preferable to current control by resistance.this isTransistor controllerPromotes the development ofLeostatWas expelled.

In the magnet motor, cogging (called teething in English), in which the field attracts the armature and makes it difficult to move when stopped, was unavoidable, and the locomotive could not be pushed and moved by hand.If you turn the shaft of the magnet motor by hand, you will feel that it is caught in a specific position as if you were rolling a dice, but if you press the locomotives of Lionel and Märklin that used a series-wound motor by hand, you can press it against the rail. The motor rotates.Also, recently, there is no cogging and you can get more torque with smooth running.Coreless motorAnd cogging, but can produce stronger torqueBrushless motorIs also becoming widespread.

For power transmission from the motor to the wheelsWorm gearIs often used.Spur gear,Bevel gearIs rarely used, but some high-end models are a type of worm gear.Coasting gearThe use of is also permitted.That is one step (less) in the formerpartsIn) bigGear ratioThis is because it is very convenient in terms of space saving and motor arrangement that the motor shaft and the drive shaft are orthogonal to each other.HoweverBraking deviceSince many worm gears used in model railroads cannot be driven in reverse from the viewpoint of safety, they are special.clutchA method of automatically disconnecting gears using the method has also appeared.However, this method was transient and was not a specification of the character reflected in the product.on the other hand,Coasting gearThe problem of reverse drive has been solved in the model using.

A coreless motor, a type of magnet motor, does not have an iron coreMoving coilWith a type motor, if you decelerate it with a spur gear, you can create a motor vehicle that pushes and moves.However, the gears that can be stored in the limited space had a gear ratio of about 1: 4, the traction force was too weak, and the maximum speed was too fast.1984 The coasting gear was developed in Japan, and a motor vehicle with both high efficiency and quietness was realized.

In these electric models, all motor vehicles move in the same way on the same track.[Annotation 17]..But then unsatisfied enthusiasts head for multiple control, which isDigital command controlWas realized as.

Method using internal combustion engine

By some enthusiasts and manufacturersInternal combustion engineA model railroad equipped with is manufactured.It is produced in small numbers but has been handed down by enthusiastic enthusiasts.For internal combustion enginesgasoline engine,Glow engineLike a real gas-electric transmissionGeneratorThings that are driven by an electric motor and propelled by an electric motor,DeceleratorThroughDriving wheelThere is something that drives.AlsoReciprocating enginenot onlygas turbineSome enthusiasts also make things that are powered by.

Sound system

1940 eraMore electricgramophoneConnected to the rail and mounted on the vehiclespeakerThere was a structure that made a sound from.Then improved,1970 eraOf steam locomotivesrodMakes a blast sound in synchronization with the movement ofPFM soundHas appeared.Also, the audio signal from an external sound sourcewirelessIn-vehicleReceiving machineThere was also something that was received by and played back from the speaker.1990 eraThe ones equipped with digital sound sources became widespread. Since the 2000s, in addition to the DCC decoder with sound function, there are also things that use conventional analog controllers such as Quantum Sound and MRC Synchro Sound Box, and output sound from the in-vehicle digital sound source according to the voltage change of the vehicle. It became so.

how to play

There is a way to enjoy putting a train model on a railroad track and running it like a real railroad car.Small models can be easily handled on a table or floor, and these are called "zashiki layout" or "floor layout".Large models can be enjoyed by laying them in the garden like a "garden railway".
Also with a sceneLayout・ Vehicles may be run on the diorama.Although layouts are often produced and owned by enthusiasts themselves, some model stores open the layout diorama provided as part of the service to customers, and the layout is rented for an hour for a fee. To doRental layoutThere is also.
Furthermore, in recent years, it has become possible to enjoy driving while watching the scene from the driver's seat by installing an ultra-small TV camera in the leading vehicle and combining a monitor TV and a controller that receive the video wirelessly. It was.In this case, you can enjoy the scene from inside the layout diorama tunnel.
There are many commercialized vehicles, even if they are Japanese models.There is also a way to enjoy collecting this.There are various ways to collect vehicles depending on the person, and collect vehicles by deciding the theme such as your favorite country, region, age, railway company, model maker, vehicle type, train, type.However, in addition to simply purchasing the finished product and viewing it, in the case of a model railroad, there are cases where the desired vehicle is modified or made by yourself, and there is also a way to enjoy running the collection by creating a layout diorama that matches the theme.
Build a vehicle
Model work is one of the basic ways to enjoy model hobbies, including model railroads.There are many different types of vehicles that can be manufactured in one bite, but the finished vehicle is meticulously processed to make it more suitable for the actual vehicle, vehicle modifications that create different formats and specifications from the original vehicle, brass, etc. It is roughly divided into scratch builds (all self-made) that build vehicles from materials such as plastic and parts.
Make a layout diorama
Another model work for model railroads is the production of a layout diorama with a scene.A group ceremony with members in the model railroad club (Module layout) And split layout diorama.Even long trains, which are difficult for individuals to realize, are relatively easy to realize with this method.
participate to the event
There are ways to enjoy it, such as observing events held by manufacturers and clubs, exchanging impressions about products such as workmanship and usability, and participating in exchange meetings and second-hand markets called swap meet.
Major events in Japan and abroad- International Model Train Convention,Model train show,O scale waistな ど
