Hornby and Hornby Dublo are both well-known model railway brands, but there are some key differences between them.


Hornby is a British model railway brand that has been in operation since 1920. It is known for producing a wide range of model trains, track systems, accessories, and scenery items.

Hornby’s products are generally made to a scale of 1:76 and use the standard gauge track width of 16.5mm, which is known as “OO” gauge. The company offers a variety of locomotives, rolling stock, and accessories based on both British and international prototypes.

Hornby’s products are widely available and popular among model railway enthusiasts.

Hornby Dublo

Hornby Dublo was a range of model railway products produced by Hornby between 1938 and 1964. It was a larger-scale system with a gauge of 20.3mm, known as “Dublo” gauge.

The Dublo range originally used a three-rail system, with a center rail for power and two outer rails for the trains to run on. The three-rail system made it easier to operate multiple trains on the same track without the need for complex wiring.

However, in the early 1960s, Hornby Dublo switched to a two-rail system, similar to Hornby’s standard OO gauge.

One of the notable differences between Hornby and Hornby Dublo is the scale and gauge. Hornby Dublo was larger than the standard OO gauge and had a slightly different track width.

Another difference is the time period of production, with Hornby Dublo being produced from the late 1930s to the mid-1960s, while Hornby has continued to produce model railway products beyond that time.

It’s worth noting that Hornby Dublo products are now considered vintage and are sought after by collectors. They have a certain nostalgic appeal and can be more difficult to find compared to current Hornby products.
