What Lionel is to U.S. model trains, Hornby is to the U.K.’s. Its 1937 “Princess Elizabeth” locomotive is considered the pinnacle of O Gauge trains. Its Hornby-Dublo “Cardiff Castle” is in the Guinness Book of World Records for running 153 miles nonstop. The Hornby-Dublo “Deltic” made news by transporting a 35-pound child on a specially made 00 Gauge trolley. And its “Flying Scotsman” was so popular, it was produced in 18 different versions.

Hornby was not, however, the first toy train in the British Isles. Train sets were first sold in England at the turn of the century, more than two decades after tinplate miniature trains were first produced in Germany and France. A man named W. J. Bassett-Lowke, “the father of British toy trains,” hired German toy train manufacturer Bing to produce sets based on British railways and began selling these imported toys.

Frank Hornby, whose Hornby Series is considered the epitome of British miniature train sets, did not come up with the concept of toy trains, either, nor was he even the first to bring them to Britain. In fact, around the turn of the century, Hornby was more interested in patenting his own invention, a construction toy set, first called Mechanics Made Easy, and then rebranded as Meccano shortly after its launch in 1907.

Meccano was a tremendous success, and it wasn’t long before Hornby’s fascination with cranes and bridge-building turned toward the railroad. In 1915, he produced a railway game called Raylo, not sold under the Hornby name, which used a clockwork locomotive, likely made by Märklin. To play Raylo, players manipulated a series of switches to prevent the engine from running into the siding or off the rails.

When the Hornby Clockwork Train, using the standard O Gauge, was finally introduced in 1920, it was considered revolutionary among toy-train enthusiasts. The Hornby Train Set employed the clever technology of Meccano, designed to be taken apart and put back together. In addition, nearly all toy trains of that era were tinplate, but the Hornby’s locomotive and coal-car were made of nickeled base plates enameled in black, red, or green, with brass trimmings.

Only three of the 120 British railroad companies were represented—London & North-Western Railway (black), Midland Railway (red), and Great Northern Railway (green). Their locomotives all had the same running number, 2710, on brass plates attached to their sides. Only the tender was trademarked with “M Ld L England” on the side for “Meccano Ltd. Liverpool, England.”

The Hornby Series was a huge success, partly because German products were so unpopular after the First World War. Around the same time, Meccano also offered a cheaper version of ...

Even though electric toy trains were produced in Germany and America starting around 1900, companies struggled with safety and the correct voltage for their tracks. So, again, Hornby, which produced an electric toy train in 1925, could be considered a little late to the game, but the company had a trick up its sleeve to one-up competitors.

The Hornby Electric Train Set, the first with a locomotive modeled after a real-life engine, was inspired by the Metropolitan Railway, now called London’s Underground Metropolitan Line, which was the first passenger subway. It had been slowly converted from steam to electric power from 1905 on, which means Hornby was able to launch its first electric toy train based on a real-life electric train rather than a steam engine.

Even so, Hornby’s electric model, which had a tinplate body and used 100 to 240 volts of alternating or direct current, was not considered entirely safe. According to some versions of the history, Parliament and the U.K. Home Office put pressure on Meccano until the company withdrew the high-voltage train set and began offering a low-voltage accumulator version.

In the late ’20s, Hornby was also under pressure to make a train on the half-size H0 scale, which was becoming increasing popular, but the company refused to relent. Two years after Frank Hornby’s death in 1936, though, the company launched its own miniaturized train set called Hornby-Dublo. It had its own scale, but it could run on any H0 Gauge track.

In the mid-’30s, Bassett-Lowke had already experienced great success importing the H0 Gauge Trix Twin Railway from Germany, which had 16.5 mm between the rails, as opposed to 33 mm on the standard O Gauge sets of the time. These electric trains were powered by a center rail that could use right- or left-hand pick-ups, meaning two locomotives could run independently on the same track.

When Meccano, now managed by Hornby’s son, launched it’s smaller-scale train in 1938, it introduced its own proportions. While the wheels ran on 16.5 mm H0 Gauge tracks, the rest of the train set was proportioned at a ratio of 1:76 (4 mm to 1 ft), instead of the 1:87 ratio (3.5 mm to 1 ft) of most H0 train sets.

Meccano made the Hornby-Dublo to be deliberately out of scale, with the wheels closer together than they should be (true scale would have required the rails to be 18.83 mm apart), because actual British train engines at the time were smaller than those in America and the rest of Europe. Otherwise, it would have been difficult to fit all the toy-train mechanics of a British toy locomotive into the existing H0 scale.

Meccano dubbed this new scale as 00 or Double 0, and the trains were named “Dublo,” intended to be pronounced as “Double O.” Because Hornby trains were wildly popular, this peculiar proportion became the standard for toy trains in the United Kingdom. In the United States, 00 Gauge means something different—a train that runs on a 19 mm track.

The company boasted that the Hornby-Dublo let you “lay out a complete model railway on your dining table.” Train fanatics loved the product for its highly detailed diecast locomotives, made using techniques Meccano had perfected in its line of diecast model cars called Dinky Toys. Hornby-Dublo was also praised for its top-notch three-rail track that allowed trains to run smoothly.

The 1958 launch of the English Electric Type 1 Bo-Bo Diesel Electric Locomotive marked two milestones for the Hornby brand—it was its first locomotive made from molded plastic rather than diecast metal, and it was the first inspired by a diesel engine, which fans of steam trains resented.

Another innovation, in 1959, was the introduction of Hornby-Dublo’s first two-rail track line, meant to compete with Rovex’s Tri-ang two-rail line. Unfortunately, enterprise brought about the downfall of the company. To keep fans happy, Meccano had to keep selling the three-rail track at the same time, at great cost.

In 1964, Lines Bros., the corporate parent of Rovex, maker of Hornby competitor Tri-ang Railways, purchased Meccano Ltd.—it wasn’t long before the two separate lines of trains were merged into one, Tri-ang Hornby. However, only two Hornby-Dublo products were fully brought into the line, the Terminus and Through Station Kit and the E3000 Locomotive, using the running number E3001.

By 1971, the Lines Bros. business had disintegrated, and the miniature railroads became Hornby Railways again. In recent decades, the Hornby brand has continued to be known for its accurate train models, and has remained a model-railroad leader in the United Kingdom.
