Introduction: The Enduring Appeal of Hornby Model Trains
For generations of railway enthusiasts, Hornby has been synonymous with model railways. From the early electric locomotives of the 1930s to today’s highly detailed digital models, Hornby has produced an extraordinary range of miniature steam engines, diesel locomotives and electric trains.
Hornby OO gauge locomotives are particularly popular with collectors. Combining British railway heritage, mechanical engineering and nostalgia, these miniature engines offer an interesting collecting field, with some rare examples attracting considerable interest from model railway enthusiasts around the world.
Whether you are rediscovering a childhood train set, building a collection of vintage locomotives or searching for a rare limited-edition model, understanding which Hornby engines are particularly desirable can help you identify some genuine collecting opportunities.
In this guide, we explore the history of Hornby OO gauge trains, highlight some of the rarest and most collectible locomotives, and explain what makes certain models more desirable than others.

A Brief History of Hornby OO Gauge Railways
Hornby’s history began with Frank Hornby, the British inventor and entrepreneur who also created Meccano and Dinky Toys.
The first Hornby model railway sets appeared in 1920, initially featuring clockwork-powered locomotives in the larger O gauge.
A major development came in 1938 with the introduction of Hornby Dublo, an electric model railway system using OO gauge. This helped establish the scale as the dominant format for British model railways.
The post-war years saw an enormous expansion in popularity. Hornby Dublo locomotives, coaches and accessories became familiar sights in British homes, while the arrival of Tri-ang Railways in the 1950s introduced another generation to the hobby.
The Tri-ang and Hornby businesses eventually came together, with the Hornby Railways name becoming established in the 1970s.
Over subsequent decades, Hornby expanded its range to include increasingly sophisticated steam engines, diesel locomotives, electric multiple units and high-speed passenger trains.
Today, the company’s historic models remain popular with collectors, while modern releases continue to attract railway enthusiasts.
Understanding OO gauge: OO gauge uses track with a 16.5mm rail spacing and models are generally built to a scale of approximately 1:76. It shares the same track gauge as HO models, although the scales are different.
The Rarest and Most Collectible Hornby Locomotives
Not every old Hornby locomotive is rare, and not every limited-edition model is particularly valuable. However, certain releases stand out because of their production numbers, unusual specifications, historical significance or popularity among collectors.
Here are some particularly interesting models to look out for.
1. Hornby Dublo Gold-Plated Flying Scotsman – Centenary Editions
One of the most unusual and exclusive modern Hornby collectables is the 18-carat gold-plated Flying Scotsman centenary collection.
Produced to celebrate 100 years of the famous locomotive, the collection featured several versions representing important stages in the engine’s history.
The gold-plated models were produced in extremely limited numbers, with just 100 examples of each of five variants.
These models are particularly desirable because of their presentation, limited production and association with one of the world’s most famous steam locomotives.
Collectors should look for:
- The correct Hornby Dublo catalogue reference.
- Original presentation packaging.
- Numbered certificate of authenticity.
- The original commemorative medallion.
- Undamaged gold-plated components.
These are among the first models worth researching if you are interested in exceptionally limited Hornby OO gauge releases.

Hornby produced a special collection of six Hornby Dublo models to commemorate the occasion.
The models featured the locomotives as they appeared at the reunion, complete with commemorative Great Gathering headboards.
The limited production run of 510 models makes this a particularly interesting series for collectors.
Finding individual examples is one thing, but assembling the complete six-locomotive collection is a much more challenging proposition.
3. Tri-ang Hornby Evening Star – Early Ringfield Motor Versions
Evening Star is one of Britain’s most historically significant steam locomotives. It was the final steam locomotive built for British Railways, completed in 1960.
Hornby produced several OO gauge versions of this famous BR Class 9F locomotive.
The early Tri-ang/Hornby examples are particularly interesting to collectors, especially the early 1970s releases featuring the Ringfield tender-drive motor.
Later versions incorporated improvements in detailing, motors and running characteristics.
Collectors often seek:
- Early production examples.
- Original BR lined green livery.
- Correct locomotive numbering.
- Original packaging and paperwork.
- Complete tenders and connecting components.
The combination of historical significance and the model’s place in Hornby’s development makes Evening Star a worthwhile addition to a vintage collection.
4. Hornby Advanced Passenger Train (APT)
The British Rail Advanced Passenger Train was one of the most ambitious railway engineering projects of the twentieth century.
Designed to explore high-speed passenger travel using tilting technology, the experimental train became an icon of British railway innovation.
Hornby’s original 1980s APT models are particularly interesting to collectors.
The early models captured the unusual streamlined appearance of the train and its distinctive tilting design.
Later versions and reissues were also produced, so identifying the original release is important.
Collectors should pay particular attention to:
- Early production examples.
- Complete powered and unpowered units.
- Original packaging.
- Intact couplings and connecting components.
- Complete sets rather than individual sections.
The APT is an excellent example of a model that appeals to both railway enthusiasts and collectors interested in British engineering history.
5. Hornby Dublo Duchess of Atholl
The LMS Princess Coronation Class locomotives were among the most impressive steam engines ever operated on British railways.
Hornby Dublo produced models of these powerful express locomotives, which remain popular with vintage railway collectors.
The Duchess of Atholl is particularly interesting because of its association with the early Hornby Dublo period.
When examining these older models, condition is extremely important. Original motors, wheels, paintwork and tender components can make a significant difference to desirability.
Complete examples with original boxes are generally more attractive than heavily used or incomplete locomotives.
6. Hornby Flying Scotsman – Early and Special Releases
Flying Scotsman is arguably the most recognisable name in British railway history.
The real locomotive entered service in 1923 and became famous for its speed, engineering and long-distance passenger services.
Hornby has produced numerous OO gauge Flying Scotsman models over the years, meaning collectors need to distinguish between ordinary production examples and special releases.
Some particularly interesting versions include:
- Early Hornby and Tri-ang releases.
- LNER apple-green versions.
- BR green versions.
- Special anniversary editions.
- Limited-edition Hornby Dublo centenary models.
- Presentation sets with numbered certificates.
The important thing is not simply finding a Flying Scotsman model, but identifying the precise catalogue number, production period and edition.
7. Hornby Thomas & Friends – Early Incorrect-Face Models
The Hornby Thomas & Friends range has developed its own dedicated collecting community.
Introduced in 1985, the range continued for more than three decades and included numerous characters from the television series.
One particularly interesting collecting area involves early Thomas models produced with incorrect facial details.
Some of these early examples were withdrawn from production, making surviving examples of interest to collectors.
The condition of the face, paintwork and original packaging is particularly important.
Other popular characters include:
- Thomas
- Percy
- Gordon
- James
- Henry
- Toby
Complete early sets and unusual production variations are worth investigating.
8. Hornby InterCity 125 – Original 1980s Releases
The InterCity 125 transformed British passenger rail travel when it entered service in 1976.
Its distinctive streamlined power cars and high-speed performance made it an obvious subject for model railway manufacturers.
Hornby’s original 1980s HST models have developed a following among collectors, particularly examples featuring the original InterCity branding and liveries.
Look for:
- Early InterCity liveries.
- Original power cars and matching coaches.
- Complete train packs.
- Original boxes.
- Special branding and variations.
Although many HST models were produced, certain early versions and complete boxed sets are more interesting than ordinary later releases.
Other Hornby Locomotives Worth Collecting
Beyond the particularly scarce examples above, there are several classic locomotives that deserve a place on a Hornby collector’s watchlist.
| Locomotive | Why collectors like it |
|---|---|
| LNER A4 Mallard | Famous streamlined design and world steam speed record |
| Sir Nigel Gresley | Iconic A4 Pacific with strong historical appeal |
| LMS Black 5 | One of Britain’s most recognisable mixed-traffic steam engines |
| GWR King Class | Large express locomotives with distinctive Great Western heritage |
| Britannia Class | Classic British Railways express steam |
| Class 08 Diesel Shunter | Popular and versatile British diesel locomotive |
| Class 31 Diesel | Classic British diesel with numerous liveries |
| Class 37 Diesel | Highly recognisable locomotive with a substantial following |
| Class 47 Diesel | One of the most widely used British diesel locomotives |
| Class 50 Diesel | Distinctive express passenger diesel with several popular liveries |
| Class 66 Diesel | Modern freight locomotive with numerous operator variations |
These models are not necessarily rare in standard production form. However, unusual liveries, early releases, retailer exclusives and limited editions can make particular examples much more desirable.
A Special Collecting Opportunity: Australian Hornby Models
For Australian collectors, there is another particularly interesting area worth investigating.
Hornby and Tri-ang produced a number of models for overseas markets, including Australian railway subjects.
One especially unusual example is the Victorian Railways double-ended diesel locomotive, numbered 5007.
The Hornby Collector Guide records this model as being released in 1958 and 1959.
It represents the Victorian Railways B Class diesel locomotive and is an interesting piece of Australian model railway history.
Its distinctive double-ended appearance makes it quite different from the familiar British steam and diesel locomotives normally associated with Hornby.
Australian-market models and unusual regional releases can be particularly interesting collecting opportunities because they may be less familiar to overseas collectors.
What Makes a Hornby Locomotive Valuable?
There are several important factors that influence the value of a Hornby OO gauge locomotive.
1. Rarity and Production Numbers
The number of models originally manufactured is an obvious starting point.
A locomotive produced in a run of 100 examples will generally have greater scarcity than one produced in tens of thousands.
However, rarity alone does not guarantee a high selling price. There must also be collector demand.
2. Original Packaging
Original Hornby boxes can make a considerable difference to desirability.
Collectors particularly appreciate:
- Original illustrated boxes.
- Correct internal packaging.
- Original paperwork.
- Certificates for limited editions.
- Matching catalogue numbers.
A locomotive in excellent condition with its original box will generally be more desirable than an identical loose example.
3. Condition and Completeness
Condition is particularly important when dealing with older locomotives.
Check for:
- Missing buffers and handrails.
- Damaged or missing connecting rods.
- Cracked plastic components.
- Repainted bodies.
- Missing tenders.
- Rust or corrosion.
- Damaged wheels.
- Motor condition.
A model that looks excellent but has been repainted or fitted with replacement parts may be less desirable to collectors seeking originality.
4. Unusual Liveries and Variations
Hornby has produced numerous locomotives in different railway company liveries.
Some releases are much scarcer than others.
Collectors should pay attention to differences in:
- Locomotive numbering.
- Nameplates.
- Tender markings.
- Paint colours.
- Transfers and lettering.
- Factory variations.
Small differences can sometimes distinguish an ordinary model from a much more interesting collector’s example.
5. Historical Significance
Models representing famous locomotives often attract consistent interest.
Flying Scotsman, Mallard, Evening Star and the Advanced Passenger Train are excellent examples.
Their appeal extends beyond model railway enthusiasts to people interested in British transport history.
How to Identify an Older Hornby Locomotive
If you have inherited a collection or discovered an old Hornby train set, identifying the locomotive correctly is the first step towards understanding its potential value.
Start by looking for the following:
Catalogue number: Many Hornby models have a catalogue reference printed on the box or included documentation.
Manufacturer markings: Look for Hornby, Tri-ang, Tri-ang Hornby or Hornby Dublo markings.
Motor type: Older locomotives can feature different motor arrangements, which can help establish their production period.
Livery and numbering: Compare the paintwork, locomotive number and nameplates against historical catalogues.
Original box: Packaging can help identify the exact release and production year.
The Hornby Railways Collector Guide is a useful reference for identifying many models released between 1955 and 2011.
Are Hornby OO Gauge Trains a Good Investment?
Hornby locomotives can be an enjoyable collecting area, but buyers should be careful about assuming that every old model will increase in value.
The strongest collector interest tends to concentrate around scarce editions, early production models, unusual variations and complete boxed examples.
A common locomotive in poor condition may have limited resale value, while an unusual limited edition with all its original accessories and paperwork may attract considerable attention.
As with antiques, coins and other collectables, buying the right example at the right price is important.
Researching completed sales rather than relying on advertised asking prices is one of the best ways to understand the current market.
