## The Museum

Note: This is a private museum and not open to the public.

It is in seven main areas:

Background

Many years ago, when I taught a "Basics of Model Railroading" class at a community college, I always took with me a "track board" (a framed piece of homasote 48" by 18") to demonstrate the various scales and gauges of the model railway hobby. On one side there was the range of popular gauges, and on the other a display of various track formations, mostly in H0 scale.

It was not until I was wondering what to do to decorate a long basement wall, that the flash idea occurred to me to expand on this nugget of model railway history to illustrate more makes, more time periods, and gauges that had not been represented before.

So that is how this museum came about. It is devoted to a representative display of toy train and model railway track as it has evolved and diversified from over 100 years ago. It may well be unique in its theme. It has been designed to include all gauges from Standard Gauge/Gauge 2 all the way through N to T. It includes all major manufacturers and a selection of secondary ones, and a cross-section of all types of trackwork and track formations produced over the years.

Gauge 2
Standard/Wide Gauge

Notes:
1. The four major makes of Standard/ Wide Gauge track (Lionel, Ives, American Flyer and Dorfan) were all interchangeable as to length, and curve. Eight pieces form a circle with a diameter (at the outside rail) of 42".
2. Lionel had patented the name of this gauge-width (2 and 1/8") as "Standard Gauge", which obliged its competitors to refer to theirs as "Wide Gauge".
3. Lionel, Ives and Dorfan all followed the 2-1 track pin arrangement, whereas AF favoured 3-0.)
Gauge 1
Modern Gauge 1 and Notes on G Scale vs. Scale 1

G Scale started out as a generic description of narrow gauge Scale 2 (1:27 or 1:28, technically Gauge 2n) trains; as opposed to Scale 1 (1:32) trains, both running on a 45mm gauge (Gauge 1) track. (The difference in scale [where it is being observed] is or should be readily noticed in the size of the track ties as between that made, for example, by LGB for Scale 2, and that by Märklin-Maxi for Scale 1.)

There has been a real resurgence in popularity of Gauge 1 for "large" trains, and some real confusion has been created by popularly referring to both the true Scale 1 trains and all the variety of narrow-gauge scale trains running on 45mm track, as "G scale". The emergence of F Scale that seeks to define an exact modelling ratio of 1:20.32 (or 15mm to the foot) for one specifically-defined scale of narrow gauge trains running on 45mm (Gauge 1) track, identified as Fn3 Scale; is a step to refine the labelling of this generic conglomeration of "large scale" trains on 45mm track. Confusing? Yes - there are as many as six or seven scales ranging from 1:32 to 1:13.7 using 45mm gauge track.

Note: the meaning of "G" has been variously ascribed to "Garden"; or "Grosse [Bahnen]" as in German for "large [trains]"). The "F" of F Scale stands for Fifteen mm to the foot, and other refining scales for trains using 45mm track are sure to emerge.
Gauge 0

Gauge 0 - European

Bassett-Lowke (UK)

Biller Bahn (Germany)

Bing Germany)

Bral (Italy)

Bral was started in 1902  by Roberto Braglia in Milan, Italy, as a toy factory, and in the 1930s it produced a successful Italian version of Meccano.
In 1947 Bral introduced a range of 0 gauge trains, using 20 V AC four-wheeled motors. For an example of a turnout, see under the "Other Toy Train Track Images" page. The track is distinguishable by a unique track connector design of a moveable latch;  and also by an unconventional third rail design (see the  "Track Identification" page). The track's identification is by research from Tony Penn, HRCA (UK).

Bub or Karl Bub (Germany)

Chad Valley was one of the UK's leading toymakers for most of the 20th century. Chad Valley had a Gauge 0 system in the 1930s with distinctively green-painted track bases and ties for its inexpensive clockwork trains in competition with Mettoy and the higher-priced Hornby range. In particular, some accessories, such as bridges and stations, were often to be found on Hornby layouts.  Chad Valley also offered a "set" oval without other track formations - see left.

Faller (Germany)

Faller is a German toy company founded in Stuttgart in 1946 by brothers Edwin and Hermann Faller. Faller now specializes in making scenery, plastic model kits and other accessories for model railroads but briefly experimented with Gauge 0.

Fleischmann (Germany)

Fleischmann was founded in Nürnberg, Germany in 1887 by Jean Fleischmann, as a toy company. the firm specialized in toy boats in the 1920s and 1930s. Fleischmann went into Gauge 0 production in 1949, but abandoned it soon after introducing its H0 trains in 1952.

Hornby (UK)

Hornby ("Hornby Series"): Gauge 0 clockwork tableau. 1930s. A Hornby electric train was the dearest wish (after a cricket bat) of every English boy of that generation. Hornby was the pre-eminent popular UK toy train make of that era. Shown here is a clockwork oval with 1 ft radius curves and with two sidings. Note however that the turnouts (points) and the curves in the sidings (spurs) are 2 ft radius. Also shown are No. 1. and No. 2 bufferstops, the standard half-straight track level (grade) - crossing, two turntables - the smaller one dating from the 1920s before the advent of larger locomotives added to the Hornby range. Also a cross-over for Hornby's double-track system that permitted an oval layout to be built with ready-made double track units of straights and curves. Hornby, unlike Märklin and Lionel, the other two popular pre-WWII manufacturers of 0 Gauge trains, never made remote-controlled turnouts (points).

JEP (France)

Mamod (UK)

Märklin (Germany)

Mettoy (UK)

The Mettoy (Metal Toy) company was founded in 1933 in Nottingham, UK. The firm is most famous for its line of die-cast toy motor vehicles of their Corgi Toys branch created in 1956, but during the 1930s the company made a variety of low cost toy trains powered by clockwork motors to compete with Hornby.

Paya (Spain)

Pionér Expressen (Denmark)

Pionér Expressen made trains in  H0 and 0 gauges. Founded  in 1948 by Knut Petersen in Copenhagen, and production was until 1965. Commemorated in a Danish postage stamp series, see my Postage Stamps - Railways and Traction. (Scroll to Denmark.) It would appear that track was made with and without red-painted ties (sleepers). See also Other Toy Train Track Images. Donated by Gilbert (Gilly) Lambert, Fla USA, identified by Paul Chapman, UK.

Lionel

LIONEL TRACK and CURVES
The Lionel design of its traditional Gauge 0 track (except for its O27 range), both pre- and post-WWII,  provides for curled tie-flanges for its slide-on track connectors (see my "Track Identification" page). The track has no camber, and Lionel (like Hornby) stamped its name consistently on the tie-edge.

The overall design is very similar to that of, and is interchangeable with, Hornby, except that
(a) Lionel favoured the 3-0 track pin arrangement, and
(b) Hornby only offered 24" and 48" diameters, whereas Lionel (its O27 range aside) offered 31", 42", 54" and 72" diameters.

Lionel T Rail
(Information courtesy Cary Coverdill. I am indebted to Cary for drawing this remarkable track to my attention.)
This track straddles the toy train era and the model railway world. It is pre-WWII, made between 1936 and 1942. While not true 'scale' track (the ties/sleepers are too large and widely spaced) the rails are roughly shaped as North American prototype railroads use, and the sections of track are joined by the use of fishplates, nuts and bolts - similar to the 40 foot long sections used for decades by the prototype.  The only diameter of curve was 72" (O72), including turnouts, to allow for operation of the near-scale, and 'true' scale prewar models Lionel built.  These included the M10000 articulated streamliners, the similarly-constructed Hiawatha, and of course the flagship of the entire Lionel production history: The model 700E Scale Hudson, and the small fleet of true scale freight cars that went with it. This trackwork is highly sought after by collectors and afficionado Lionel trains operators alike. The only components available are: 15" straight, O-72 curve (16 sections per full circle), a 90 degree crossing, plus manually and remote control O-72 turnouts.  Extremely pricey in today's market, curve pieces sell for \$18 and up, with straights commonly selling for close to \$30. A full set of connecting hardware (original, like new) consisting of one under-rail clip (center rail - like modern O-scale or HO), two fishplates and four each nuts and bolts sells for over \$10, but the look, the very rigid nature of the track, and the die-cast ties (painted black) all give a fantastic appearance - indeed the Cadillac of "toy train" track. (Some turnouts are illustrated in Other Toy Train Track Images ).

027 and Super-O
Notes:
1. These are of the same gauge width as Gauge 0, but 027 or 0-27 came to be a generic term in North America for a more affordable range of Gauge 0 clockwork and electric trains. Its major manufacturer was Louis Marx & Company who started to produce cheaper Lionel-style clockwork and electric trains during the Great Depression and after WWII. Its track was lighter (with a rail height of approximately 7mm, as opposed to approximately 9mm for Gauge 0), and since eight of its curves formed a 27 inch diameter circle, it became identified as "027" track. (Somewhat confusingly, Marx also produced 042 curves in this light range.) Its introduction forced Lionel to compete with a similar inexpensive range, producing O27, and also O42 and O54 in this lighter track.
2. The same phenomenon occurred in the same time period in the UK, with competition from such firms as Chad Valley and Mettoy, which likewise forced Hornby to compete in the same range with its "M" series, although Hornby did not reduce its standard Gauge 0 rail height. (It has never been determined what "M" stood for.)
3. The "027" designation, however, did not migrate to Europe, nor is it appropriate to describe the earliest Gauge 0 track in that way, even though rail heights at the time of the development of Gauge 0 were in the same rail height range as 027.
4. The post-WWII Lionel "Super-O" range (see below for an example of its track) gets included in this "027" category because of its similar lesser rail height, but correspondent Cary Coverdill advises: "While it is true that the cross-section of Super-O is more like 0-27 than 'full height' 0-gauge, the diameter of all Super-O curves was 36". My suggestion would be to indicate this distinction between 0-27 and Super-O.")
5. Throughout all of these web pages, I refer to "number" gauges with Arab numerals (00, 0, 1, 2 etc.), but it should be noted that Lionel refers to Gauge 0 with O as a letter rather than a number, therefore also O27, O31, O42, O54, O72, Super-O and so forth. (Info courtesy Cary Coverdill.)
Gauge 0 - Envoi
There is no doubt that Gauge 0 dominated the toy train era of living memory, and for those who recall it so fondly today, it was in fact a synonymous term for that era: Gauge 0 = toy trains, and Gauge 0 remains the embodiment of magic of that age for generations of youngsters.

The pieces displayed here may also answer, we hope, some questions of those who collect, have inherited, or simply stumble across something that was stashed away in an attic for years and years, waiting to be rediscovered ...

Gauge S

EM GAUGE (18 mm) P4 GAUGE (18.83 mm)

The UK equivalent of H0 scale (1:87) in popular use today (British H0 is largely defunct) is 00 scale (1:76), whereas H0 gauge, to correspond to its 1:87 ratio, is 16.5 mm. The result is that British prototype stock running on H0 gauge is slightly but noticeably under-gauged. The equivalent correct gauge is 18 mm, or more precisely, 18.83 mm.

Today, other fine scale track options are also available.

The Transition from Toy Trains to Railway Modelling

As a gross oversimplification, this could be defined as having occurred with the appearance of Gauges 00/H0. Certainly scale modelling existed before WWII, but it was a close-knit fraternity that “scratch-built” its models, and/or obtained its materials and parts from specialty houses such as Bassett-Lowke in the UK.

The end of WWII saw the disappearance of tinplate and cast metal as the media of choice; giving way to brass and plastic moulding. The latter improved in its detailing by leaps and bounds to the state of the art today, followed closely by the emergence of nickel silver as the standard metal for all model track.

With respect to track, the key transition from toy trains to railway modelling was the appearance of flexible lengths of track that allowed the modeller to break away from the geometric uniformity of sectional or “snap track” track lengths. Not that the latter died out, in fact sectional or “snap” track, usually now offered with moulded track bases, remains strongly on the market today (with an eye to beginners), but flexible lengths enable a modeller to a closer representation of  reality. Modellers are still beholden however to the track formations (points, crossings, slips) that a particular manufacturer has to offer, unless they take the plunge to hand-build their own track and create their own “special work” formations.

HORNBY-DUBLO

WRENN

TRIANG (TRIANG-ROVEX and TRIANG-HORNBY)

TRIANG-ROVEX, TRIANG-HORNBY
Quick history:
Rovex Plastics Limited  was set up in 1946 and initially made model cars, but moved into the model train market to supply trains to the UK department chain Marks & Spencer. It was acquired in 1951 by Lines Brothers Ltd., who moved the Rovex plant to a new factory at Margate, Kent, UK, in 1954, and the updated product was sold under the Triang name (three Lines [brothers] = a triangle, hence Tri-ang). Triang trains had already appeared in hobby shops in 1953, and with the move to Margate, proved strong competition to Hornby-Dublo and Trix Twin. In 1964, Meccano Ltd. ceased production of Hornby-Dublo and was acquired by Triang, with the range now being marketed as Triang-Hornby. In 1971, Lines Bros. went into receivership. The former Triang-Hornby was sold to Dunbee-Combex-Marx (DCM), and became Hornby Railways in 1972. DCM in turn was liquidated in 1980, and Hornby Railways became Hornby Hobbies, surviving into a renewed sound financial footing by 1986.

GRAHAM-FARISH

Graham-Farish Formoway and Liveway track
This UK manufacturer entered the model railway market in the late 1940s, offering in the 1960s a popular and complete system of 00 flexible track and track formations that filled for the serious modeller a real vacuum between the early 1950s Wrenn fibre-based track and the subsequent emergence of Peco as a predominant supplier of trackwork in most major scales.
Note: Not in the museum, but illustrated here from the GF 1965 Handbook.

PECO

As Peco is still being made, it is not really a "museum" item, but it has been included to bring the evolution and development of H0/00 (16.5mm) track since the end of WWII up-to-date. It is still considered today as the premier ready-to-lay track throughout the model railway world. During the 1960s Peco emerged as the versatile track of choice with Code 100 silver nickel rail, and a setrack (sectional track) system (ST) for those not yet ready to make the leap to flextrack. It has since branched out to offer its track in Code 75 fine scale, and also in Code 83 for North American modellers.

HORNBY RAILWAYS

The Tri-ang Group was disbanded and sold in 1971, and the system which had been known as Triang-Hornby was renamed Hornby Railways in 1972, with production continuing at the former Lines Bros. Margate, UK factory. The specification of a large part of the range was upgraded to make it more attractive to adult enthusiasts, and improvements were carried out to provide finer scale wheels, wire handrails on locomotives, better paint finishes on plastic bodies and the high definition printing of logos. All Hornby manufacturing was moved to China in 1995.

GAUGE 00 (16.5mm) - TRIX

Three major makes went through definable "generations" of track designs. They were Trix, Märklin and Triang-Rovex/Hornby.
Of these, Trix was arguably the most complicated, not only because of the longevity of the production period, but also because there were two companies involved - Trix-Twin in the UK, and Trix Express in Germany. For a history of the Trix Company, see under Toy Train Manufacturer Histories.

There were three major generations of Trix 3-rail track:
Generation 1 (UK and Germany)
The original bakelite based tinplate rail track from 1935 to the mid 1950s. The turnouts for this were:
Pre-war: full length rail with a single external solenoid actuator for the remotes and large extension for the operating lever and solenoid which became an obstacle to compact track arrangements.
Post-war (UK only) 3/4 length straight/full curve with a double coiled internal solenoid for the remote actuator. Much smaller design could handle back-to-back arrangements.
Generation 2 (UK and Germany)
A fibre based track, tinplate rails with a blackened centre rail. Presumably an attempt to disguise the fact there was a third rail present. Mid 1950s to mid 1960s. The turnouts for these also had two versions:
a.) The earlier one had a full straight with a 4/5 curve - good only for Trix rolling stock
b.) A later "Universal" version was introduced (in the UK only) that could accommodate any kind of rolling stock, from the original coarse Trix wheels to fine-scale.
Generation 3 (Germany, but see Note 5)
A very high quality plastic based track with nickel silver rails. It also had a blackened centre rail. This was introduced in the mid-1960s to succeed Generation 2 and remained available until around 1998.
Notes:

1. Essentially, what is identified as Trix Express was made in Germany, and what is identified as Trix Twin was made in the UK. The occasional piece of Trix Express track with “Made in England” molded in has been found but appears to be an exception.
2. The original bakelite track was made by both Trix Express and Trix Twin, but all the pre-WWII points were the same, either one fat solenoid or a manual lever (Bing-style) perpendicular to the track. There was a Trix Express version with the track indicator illuminated internally, mostly sold in America.
3. Electrically-operated points with the solenoids were made both in Germany by Trix Express, and by Trix Twin in the UK. There was a post-WWII Trix Twin version with a three-quarter straight track length. Other than two small terminals the appearance of manual vs remote was identical.
4. With the introduction of Generation 2 came the “lollipop” connector. Again Generation 2 was made by Trix Express in Germany and by Trix Twin in the UK. The earlier non-universal version points designs were very similar with the exception that Trix UK used the same grey plastic cover for manuals and remotes, Trix Express used a smaller cover for the manuals, and the remotes had a rotating direction indicator. The later “Universal” points were only made by Trix UK.
5. With the introduction of Generation 3 came the “fishtail” connector, and since Trix Twin had already gone out of business by then, it was made only by Trix Express, except that it was also sold by Trix Twin in the UK as Trix “Supertrack” from 1964 to 1973 (which is when Trix Twin went out of business). One interesting point is that plastic inserts were offered to convert these points and crossovers to accept scale wheel flanges. NOT universal – it was one or the other. These conversion kits are VERY rare.
6. Trix made track interfaces that would allow one to connect Generation 2 track (lollipop) with Generation 3 (fishtail) track. There were also ramped transition rails to connect Generation 1 Bakelite to Generation 2 fibre-based track.
7. With the introduction of 2-rail in 1967, the “Twin” concept of two trains running independently was still possible by using overhead catenary as a second power source, but Trix had lost the uniqueness of twin running from the track. In fact any other manufacturer with a catenary option (such as Märklin) could offer the same.

GAUGE H0 - CENTRAL EUROPE

MÄRKLIN
Over its long period of manufacturing H0 scale trains, Märklin has offered three major generations of track design, namely M (for Metall [metal]), K (for Kunststoff [plastic]), and C (for Click [as in together]). Märklin introduced its H0 scale trains in 1935, and with it came its first version of M track (Version A) , the original 3600 - 3700 series, with a solid metal base, two outer running rails of one electrical polarity, and a centre pick-up rail for the other.  (This version is compatible [except for a slight difference in track-base height], with Hornby-Dublo 3-rail track.)
The second version (Version B) of M track was offered in 1953 at the same time as the firm's major design change to stud contact pick-up or electrification. Märklin had reportedly acquired the rights for its "Modell Gleis" [model track] from the French firm of Vollard & Brun in the early 1950s, who produced track consisting of plastic ties embedded in a metal roadbed. Märklin copied and improved it, at the same time converting the method of current pick-up design to stud contact operation. This was a seminal marketing decision on the part of Märklin as the hobby generally was moving to electric 2-rail operation at the time.
Note on 2-rail versus 3-rail and stud contact operation:
The major advantage of 2-rail operation is of course prototypical appearance, and Märklin sought to address that issue (indeed arguably, successfully) by its introduction of a largely invisible and unique stud-contact system of power supply. In offering stud contact pick-up, Märklin sought to retain the major advantages of this amended form of 3-rail operation in that it does not require the necessary wiring for reverse loops and also retained the option of train-activated accessory operation by means of short isolated running track lengths wired to the accessory and "tripped" by the passing of the train wheels.
Version B of the M track was however expensive because of its production requirements and did not sell well, whereupon Märklin produced its more economical 5100-5200 Version C of M track in 1956.
In 1969, Märklin introduced its K track, its aim to have its track design be closer to those being marketed by competing manufacturers of the day, but M track continued to be available until 1990.
In 1996, Märklin reverted to offering a track with (this time) a molded track base - C track.
Note: A converter track was offered from M track to K track.

GAUGE H0 - NORTH AMERICAN

In the years following WWII, the model railroad hobby in H0 gauge exploded. The initial common track makes were Tyco, Atlas, AHM (Associated Hobby Manufacturers) and Shinohara. Brass rail was initially favoured for its electrical conductivity, but its chronic tarnishing led to its replacement by nickel silver. In many respects, the market was also an international one, and the various manufacturers’ offerings were more or less interchangeable, as Code 100 (0.100” rail height) was standard until the later appearance of Codes 83, 75 and 70.

For those who preferred to build their own track, there was Tru-Scale, or individual track components from a specialty house for total hand-laid assembly. Notwithstanding the fundamental change to layout design made possible with flexible track lengths, sectional or “snap” track (now enhanced with sturdy molded track bases) remains a strong segment of the market, especially for beginners.

Represented Makes and Gauges

Preamble:
Scale and Gauge
Scale is the proportion of the model to the prototype. (The prototype standard gauge is 1,435 mm or 4ft 8.5in.) Scale is usually represented as a ratio, e.g. 1:87, so that 1 inch of model represents 87 inches of the prototype. Scale is also sometimes expressed as millimetres to the foot, e.g. 4 mm scale, meaning that 1ft of prototype is represented as 4 millimetres of model.
Gauge is the width between the rails, measured from inside edge to inside edge, or from centre-top to centre-top of rail.
Manufactured "narrow-gauge" track, (i.e., representing a prototype track of less than the 4ft 8.5in prototype standard gauge width (not to be confused with Lionel's toy train "Standard Gauge") is usually produced in a "lower" readily available gauge with broader ties in order to conform to scale. For instance, Scale 1 narrow gauge would be represented by a Gauge 0 track with larger ties that conforms to Scale 1, than that of Gauge 0 track. Common prototype narrow gauges are 3ft, 3ft 6 in, and 1m.

Important Note: The relationship between scale and gauge was the most significant defining distinction between the toy train era and its evolution into "railway modelling" or "model railways" that took centre-stage after WWII. The "toy train" era, that is to say the age of mostly tinplate-manufactured toy trains in all gauges produced before WWII (other than the beginnings of model trains produced and marketed by emerging specialty firms such as Bassett-Lowke in the UK), did not concern itself with the niceties of scale - its products were really defined only by gauge. The first efforts in the non-specialty market to start to define scale came with the advent of Märklin and Hornby-Dublo 00 trains in the 1930s. References to scale below in the larger gauges are therefore generally qualified as "Modern Day".

"G Scale"
G Scale started out as a generic description of narrow gauge Scale 2 (1:27 or 1:28, technically Gauge 2n) trains; as opposed to Scale 1 (1:32) trains, both running on a 45mm gauge (Gauge 1) track. (The difference in scale [where it is being observed] is or should be readily noticed in the size of the track ties as between that made, for example, by LGB for Scale 2, and that by Märklin-Maxi for Scale 1.)

There has been a real resurgence in popularity of Gauge 1 for "large" trains, and some real confusion has been created by popularly referring to both the true Scale 1 trains and all the variety of narrow-gauge scale trains running on 45mm track, as "G scale". The emergence of F Scale that seeks to define an exact modelling ratio of 1:20.32 (or 15mm to the foot) for one specifically-defined scale of narrow gauge trains running on 45mm (Gauge 1) track, identified as Fn3 Scale; is a step to refine the labelling of this generic conglomeration of "large scale" trains on 45mm track. Confusing? Yes - there are as many as six or seven scales ranging from 1:32 to 1:13.7 using 45mm gauge track.
Note: the meaning of "G" has been variously ascribed to "Garden"; or "Grosse [Bahnen]" as in German for "large [trains]"). The "F" of F Scale stands for Fifteen mm to the foot, and other refining scales for trains using 45mm track are sure to emerge.

Successive Track Series
Some manufacturers have brought out successive series of tracks:
Lionel 0 [traditional tinplate {compatible with Hornby Series}, Super 0 and Fastrack];
Hornby Gauge 0 [Meccano and Hornby Series];
Trix 00 [bakelite, fibre base, plastic base];
Triang-Rovex/Hornby 00 [Standard, Series 3, Super 4, System 6];
Märklin H0 [M track, K track, C track];
Triang-Rovex TT [Type A and Type B].
Several H0 makes such as Fleischmann [Profi], Roco, Bachmann [EZ track], Lifelike and Atlas offer track with pre-molded track bases..

Code
Where encountered in describing model track, "Code" refers to the height of the rail. For instance "Code 100" is rail 0.100 of an inch high, and has been the traditional standard in H0 Scale. H0 fine-scale variations are Peco and Atlas Code 83 (0.083) and Shinohara Code 70 (0.070). N scale has been traditionally Code 80, but Code 55 and Code 40 are now on the market.

Miscellaneous
Not all items are positively identified. There are some "mystery" pieces, as not all manufacturers identified their track in the tinplate years.

Quoted diameters of track circles with the exhibit images vary from inside-to-inside rail to centre to outside-to outside rail.

Represented Track Formations:
Notes:

1. Track bases and/or ties. These are tinplate, bakelite, plastic, rubber compound, milled wood or fibre according to age, gauge size and manufacturer. The rails themselves are usually tinplate, brass, steel, steel alloy, nickel silver.

2. Turnout operation. Pre-WWII turnouts are mostly hand-operated (exceptions are Lionel and Märklin), post-war turnouts and slips may be hand- or electrically-operated, and hand-operated formaitons are commonly convertible by means of an add-on switch machine by various manufacturers.

3. Frog number. Today's model railway turnouts are usually referred to as a # 4, 5, 6, 8, 10 and so forth (known as the frog number). The frog number of a turnout is an expression of the degree of the diverging route's radius sharpness. For instance, in HO scale, the converging inside rails of a #6 turnout where they meet (at the "frog") measure 6 inches from the frog to the toe of the turnout. In N scale, the equivalent for a #4 turnout is approximately 2.2 inches, for a #6, 3.27 inches, and for a #8, 4.36 inches.
A #4 turnout is therefore "sharper" (has a tighter radius) than a #6; a #6 is "sharper" than a #8; and a #8 is "sharper" than a #10.

4. Turnout anatomy. The "toe" of a turnout is where the rails of the turnout diverge (the switchstand end!).
The "heel" of a turnout is the other end of the turnout where the two tracks have diverged.
