The History of Hornby Trains: From Clockwork Railways to a British Collecting Classic
Follow the story of Hornby trains from their clockwork beginnings in 1920 through Hornby Dublo, Tri-ang Hornby and Hornby Railways, with advice for vintage collectors.
A Hornby train set is more than a locomotive and a loop of track. For generations, it has been the beginning of a miniature world: a station waiting for passengers, a goods yard with wagons to shunt, and a railway that grows a little further with every birthday or Christmas.
The history of Hornby trains follows a remarkable journey through British toy-making. It begins with Frank Hornby and his Meccano business in Liverpool, moves from clockwork tinplate to electric model railways, and takes in Hornby Dublo, the Tri-ang years and the familiar Hornby Railways name.
Frank Hornby: the Meccano connection
Before Hornby became synonymous with model trains, Frank Hornby had established his reputation with Meccano. His construction system encouraged children to understand machinery by building it themselves, using reusable metal components joined with nuts and bolts.
That practical approach carried into the early Hornby trains. Rather than beginning as finely detailed miniatures intended mainly for display, they were robust mechanical toys with an unmistakable connection to the workshop.
The Hornby name had appeared on an educational Meccano product before the railway range arrived. However, 1920 is the key starting point for the Hornby trains story and the date around which the brand marked its centenary in 2020.
1920: the first Hornby clockwork trains
The first Hornby trains appeared in 1920. They were O-gauge models powered by clockwork, with metal pressings held together using Meccano nuts and bolts. An owner could dismantle and reassemble the early locomotive, making the connection with the construction system especially clear.
The initial locomotive was an 0-4-0, a wheel arrangement with four coupled driving wheels and no separate leading or trailing wheels. It was the foundation of a range that soon expanded beyond a simple train running round a track.
Locomotives, coaches, wagons and accessories allowed owners to create a recognisable railway scene. Stations and lineside details gave the trains somewhere to go, while additional rolling stock introduced new possibilities for play.
For collectors today, early O-gauge Hornby has a distinctive presence. Its size, metal construction and period decoration connect it closely with the tinplate toy tradition.

The 1920s: electricity and a railway community
Electric Hornby trains joined the range in 1925. This broadened the possibilities beyond winding a spring motor and watching the train run until its stored energy was spent.
Electrical systems evolved during the early years, so an old electric locomotive should never be assumed suitable for a modern controller or household supply. Identification and an appropriate safety assessment matter far more than simply seeing whether it still runs.
The growing hobby also acquired a community of its own. In 1928, the company established a membership scheme called the Hornby Railway Company. Its name captured an important part of the appeal: a child was not merely playing with a train but imagining themselves in charge of a railway.
1938: Hornby Dublo brings the railway indoors
Hornby Dublo was launched in 1938. The new OO-gauge range offered a substantially smaller alternative to O gauge, making a model railway more manageable in the home.
Instead of the earlier pressed-metal approach, the first Dublo locomotives had cast-metal bodies. Early subjects included the LNER A4 Pacific Sir Nigel Gresley and an N2 tank locomotive. Both clockwork and electric versions were available before the Second World War.
This was an important change in the character of the hobby. Smaller trains made it easier to imagine a more extensive railway within a limited space, while recognisable locomotive types strengthened the link with the real railway.
For anyone new to collecting, the names can be confusing. O gauge and OO gauge are not interchangeable systems, and the historic Hornby Dublo range should not be treated as simply another name for every later Hornby OO model.
Wartime interruption and the post-war return
The Second World War interrupted Hornby train production. Hornby Dublo returned after the war, but without its pre-war clockwork range.
The post-war electric railway became a familiar part of the Hornby story. Locomotives, coaches, wagons and buildings could be brought together into a layout that was gradually expanded and refined.
For many collectors, this period has a particular emotional pull. A locomotive may recall a family layout, a favourite catalogue page or a set carefully put away between visits. That personal connection helps explain why well-used models can be treasured alongside fine boxed examples.
Three-rail and two-rail Hornby Dublo
One of the most recognisable features of early electric Hornby Dublo is its three-rail track. In addition to the two running rails, a central conductor rail supplied power.
Hornby Dublo introduced a two-rail system in 1959 as competition within the model railway market intensified. The distinction remains important when identifying a locomotive or buying components for an existing collection.
A model’s gauge alone does not establish electrical compatibility. Check whether it belongs to the two-rail or three-rail system, whether it has been converted, and what controller and track it requires. Body appearance and a familiar brand name are not enough.
Tri-ang competition and the changing market
By the late 1950s and early 1960s, Hornby faced strong competition from Tri-ang Railways. Tri-ang used plastic-bodied models and manufactured at a purpose-built factory in Margate, Kent.
The competing ranges reflected a changing market. Price, production methods and the expectations of railway modellers all mattered. Hornby Dublo continued to develop, but Meccano Ltd faced financial difficulties.
In 1964, Lines Bros, the group behind Tri-ang, acquired Meccano Ltd. The Tri-ang Hornby name followed in 1965. For collectors, this is a significant dividing line: the history of the Hornby name continued, but it was no longer simply the history of the original Liverpool-made range.
The Tri-ang Hornby years
The combined name brought together two familiar railway brands. Production associated with the continuing range centred on Margate, and the models reflected both contemporary railway changes and an interest in earlier locomotive liveries.
Diesels in British Rail blue shared the wider story with steam locomotives recalling the railways of previous decades. Familiar subjects such as Flying Scotsman and Evening Star helped connect the model railway with engines enthusiasts recognised.
Some former Hornby Dublo tooling passed to G&R Wrenn, creating another branch of the collecting story. A Wrenn model may therefore have a connection with an earlier Dublo design without being an original Hornby Dublo issue.
Boxes, catalogues, markings and production details become particularly useful when researching these overlapping histories.
1972: the Hornby Railways name
Following the break-up of the Lines Bros group, the railway range adopted the Hornby Railways name in 1972. Production continued at Margate.
The range increasingly addressed the interests of adult enthusiasts as well as younger train-set owners. Improvements included finer wheels, separate wire handrails on locomotives, better paint finishes and more detailed decoration.
This direction helps explain Hornby’s broad appeal. A first train set could introduce the hobby, while additional locomotives, rolling stock and scenic details allowed a railway to become a longer-term project.
From British production to a modern model railway brand
During the 1990s, Hornby transferred manufacturing from Britain to the Far East. This marked a major change from the Margate manufacturing era, and the later introduction of more finely detailed locomotives helped refresh the range’s appeal to railway modellers.
Margate nevertheless remained an important part of Hornby’s identity. Following a temporary relocation, the company’s offices returned to its historic Margate site in 2019. In 2020, Hornby celebrated a century since the introduction of its first clockwork trains.
Why Hornby’s different eras still matter
Hornby’s history is not one unchanging product range. It includes large clockwork tinplate trains, Liverpool-made Dublo, the Tri-ang Hornby period and later Hornby Railways models.
Each era offers a different collecting experience. Early O gauge has the visual impact of a substantial mechanical toy. Dublo attracts interest through its cast-metal construction and distinctive railway systems. Tri-ang Hornby and later models can recall the colourful catalogues and expanding home layouts of another generation.
Choosing a period or theme makes a collection easier to understand. You might focus on a locomotive class, a railway company, original train sets or the accessories that brought a miniature station to life.
What to check when buying vintage Hornby trains
Start with identification. Look for maker’s marks, catalogue numbers, gauge, power system and the correct packaging. Similar-looking locomotives can belong to different production periods or have replacement bodies and mechanisms.
Condition should be described specifically. Check for missing couplings, damaged buffers, corrosion, cracks, paint loss and signs of repair. On clockwork models, ask about the mechanism and winding key. On electric models, an untested description should not be interpreted as a promise of working order.
Original boxes, instructions and accessories can add historical interest, but a box should match the model. Repainting, replacement parts and conversions are not automatically problems for a running collection, provided they are disclosed.
There is no single value for an old Hornby train. Rarity, version, condition, originality, completeness and demand all play a part. Compare genuinely similar sold examples rather than assuming that age or an ambitious asking price proves value.
A small railway with a long history
Hornby’s lasting appeal comes from its ability to make a railway feel personal. A locomotive is an object to admire, but it is also the beginning of a journey, a timetable, a landscape and a story.
From the clockwork trains of 1920 to the development of more detailed model railways, the brand’s history reflects changing materials, manufacturing and ambitions. For collectors, understanding those changes makes each surviving model more interesting.
