Understanding Model Railway Eras: The Complete Guide
If you've spent any time browsing model railway products, you'll have noticed a small "Era" number attached to almost everything — a locomotive, a coach, even a signal box kit. This number is one of the most useful tools available to modellers, and understanding it properly will help you build a more accurate, coherent layout. This guide explains where the Era system came from, what each Era means, and how to use it with confidence.
What is the Era system?
The Era system is a numbered timeline used by British model railway manufacturers and retailers to describe which period of railway history a model represents. Each Era corresponds to a distinct chapter in British railway history — a change of ownership, a new corporate livery, a shift in locomotive numbering, or a major reorganisation — making it easy to identify, at a glance, whether two models are appropriate to run together.
The concept didn't originate in Britain. It traces back to a European "Epoch" system used by model railway associations across the continent to describe broad periods of railway history, dividing the story of European railways into a small number of major chapters. The system was brought to the UK market by Bachmann, which adapted the idea and originally defined 9 Eras tailored specifically to British railway history. Hornby later extended and refined this into an 11-Era system, splitting the modern privatisation period into finer detail. Hornby's 11-Era version has since become the standard most widely used across the hobby today — by manufacturers, retailers, and modellers alike. Model Rail Database uses Hornby's 11-Era system, as it offers the most granular and widely recognised framework for the modern hobby.

A note on overlapping dates
Look closely at the official date ranges above and you'll notice something that catches many people out: several eras overlap. Era 5 (1956–1968) overlaps with Era 6 (1957–1971), which overlaps with Era 7 (1971–1986); Era 8 (1982–1997) overlaps with both Era 7 and Era 9 (1996–2008); and Era 10 (2006–2017) and Era 11 (2014 onwards) overlap with their neighbours in the same way.
This is not an error — it's by design. A livery change or corporate rebrand didn't happen to every locomotive and coach on the network overnight. New liveries were rolled out gradually, sometimes over many years, while older stock continued running in its previous colours long after a "new" era had technically begun. The overlapping ranges reflect this reality, capturing the years during which two eras' liveries could genuinely be seen running side by side.
Because of this, Era numbers are best treated as a helpful guide for planning a coherent layout — not a strict rulebook. Heritage railways, preserved stock, and vehicles slow to be repainted all legitimately mix eras in real life, and there's nothing stopping you doing the same on your layout.
The 11 Eras (Hornby system)
Era 1: Pioneering (1804–1869)
The birth of the railway, from the first steam locomotive-hauled journeys through to the "Railway Mania" of the mid-19th century, when dozens of competing lines were built at a rapid pace. This era covers pioneering locomotives and the earliest, most experimental years of rail travel, before liveries and operating practices had standardised. Ready-to-run models of this period are rare, so many modellers of this era work with kits or scratch-built stock.
Era 2: Pre-Grouping (1870–1922)
The late-Victorian and Edwardian "golden age" of the railways, when the network reached its greatest extent and was operated by well over a hundred independent companies, each running its own distinctive, often ornate livery — the Great Western Railway, London and North Western Railway, London, Brighton and South Coast Railway, Caledonian Railway, and Great Central Railway among them. This colourful diversity makes Era 2 a popular choice for modellers who want strong regional character.
Era 3: Grouping — The Big Four (1923–1947)
On 1 January 1923, the Railways Act 1921 consolidated around 120 independent companies into four large regional groups: the Great Western Railway (GWR), London, Midland and Scottish Railway (LMS), London and North Eastern Railway (LNER), and Southern Railway (SR). This era spans the classic age of express steam — famous names like Flying Scotsman and Mallard belong here — through to the disruption of the Second World War. It remains one of the best-supported eras for ready-to-run models.
Era 4: British Railways – Early Emblem (1948–1956)
The Transport Act 1947 brought the "Big Four" together under state ownership, and British Railways came into being on 1 January 1948. This era is identified by the first British Railways emblem — a lion standing on a wheel, informally known as the "cycling lion" — along with "blood and custard" (crimson and cream) coaching stock. Steam remained dominant throughout.
Era 5: British Railways – Late Crest (1956–1968)
Marked by the introduction of British Railways' second emblem in 1956: a heraldic crest featuring a lion rampant holding a wheel, nicknamed the "ferret and dartboard" by enthusiasts. This era covers the 1955 Modernisation Plan, the rapid introduction of diesel and electric traction, and the final years of mainline steam, which ended in 1968. Often called the "Transition Era," it's one of the most popular periods to model, thanks to the striking contrast of steam and early diesel types working alongside one another.
Era 6: British Rail – Blue, Pre-TOPS (1957–1971)
In 1965, British Railways rebranded as British Rail, adopting corporate Rail Blue livery and the now-iconic double-arrow logo. This era is described as "Pre-TOPS" because the new blue livery began appearing on locomotives and stock before the computerised renumbering system (TOPS, see Era 7) was introduced — so locomotives in this period still carried their earlier numbering.
Era 7: British Rail – Blue, TOPS (1971–1986)
From 1971, British Rail introduced the Total Operations Processing System (TOPS), a computerised system that gave every locomotive and multiple unit a standardised class and number (for example, Class 87). Visually, this era continues the corporate blue and blue/grey liveries of Era 6, but with the new TOPS numbering applied. This period also saw the introduction of the High Speed Train (HST/InterCity 125) from 1976.
Era 8: British Rail – Sectorisation (1982–1997)
From 1982, British Rail reorganised around distinct business sectors rather than geographical regions, each with its own branding. Passenger sectors included InterCity, Network SouthEast (launched 1986, in its instantly recognisable red, white and blue livery), and Regional Railways (from 1989); freight was split into sectors including Trainload Freight and Railfreight Distribution, the latter known for its bold triple-grey livery. The variety and colour of sector liveries make this a popular and visually rewarding era to model.
Era 9: Privatisation (1996–2008)
Under the Railways Act 1993, British Rail was broken up and privatised: infrastructure passed to Railtrack (later Network Rail), passenger services were split among competing franchised Train Operating Companies, and rolling stock was owned separately by leasing companies. This era covers the first wave of privatised operators, along with the opening of the Channel Tunnel and the arrival of new high-speed multiple units.
Era 10: Network Franchising (2006–2017)
As passenger franchising matured, competitive tendering brought new operators, liveries and investment to the network, alongside major infrastructure renewal projects and the completion of High Speed 1. This era reflects a period of consolidation and modernisation within the privatised railway.
Era 11: Present Day (2014 onwards)
The current era, covering the growth of open-access operators, the introduction of new Hitachi bi-mode trains (Class 800/802/803), and the various changes in franchise management — including government intervention when franchises have failed. Any new-to-market model representing the present-day railway falls under Era 11.
A note on "Era 12"
Following the rollout of a new unified Great British Railways (GBR) brand and livery, some corners of the hobby have begun informally referring to a new "Era 12" to describe this next chapter of the railway. At the time of writing, this hasn't been formally adopted by Hornby or Bachmann — GBR-liveried models are still being catalogued under Era 11, Present Day. We're keeping an eye on this and will update our era guide promptly if and when Era 12 becomes official.
How to use Era numbers when buying models
Era numbers appear throughout model railway packaging, product listings, and retailer search filters, making it easy to build up a fleet of locomotives, coaches and wagons that all belong to a consistent period.
Some models are valid across more than one era — for example, a wagon design that remained in service, largely unchanged, through several livery changes. These are shown with a range or a pair of era numbers, such as "Era 2–3" (valid throughout both eras) or "Era 5/6" (typically used for two adjacent eras where the model was seen running in both).
Ultimately, the Era system is there to help you plan and buy with confidence — not to police your layout. Many modellers deliberately mix eras to represent heritage railways, preserved locomotives visiting the mainline, or stock that was simply slow to be repainted. As Bachmann puts it: it's your railway, run it your way.
A quick comparison: Hornby vs Bachmann
Because Bachmann's original 9-Era system is still in occasional use, it's worth knowing how it differs from the 11-Era Hornby system used throughout this site:
| Hornby (11 eras) | Bachmann (9 eras) | |
|---|---|---|
| Era 1 | Pioneering, 1804–1869 | 1804–1875 |
| Era 2 | Pre-Grouping, 1870–1922 | 1875–1922 |
| Eras 9–11 | Split into three: Privatisation (1996–2008), Network Franchising (2006–2017), Present Day (2014 on) | Combined into one: Post Privatisation, 1995 onwards |
The two systems agree closely from Era 3 through Era 8. The main practical difference is at the modern end of the timeline, where Hornby's finer-grained Eras 9–11 offer more precision than Bachmann's single "Era 9 onwards."
