The history of electric model trains goes back to the 1920s and many of the first and best manufacturers were British. During WWII, most British industries, including toy train manufacturers, turned to war production. However, the hobby was vibrant between world wars and peaked during the 1950s and 1960s. Many of the best known names in the English railway hobby trace their lineage back over 75 years.
Tri-ang Model Railways - In 1946, Rovex Plastics Ltd. was founded and at first made toy cars but began producing plastic electric trains in 1950 with an OO set sold for Christmas. In 1951, the company was bought by Lines Bros., which changed the company name to Tri-ang. In the late 1950s and the 1960s, Tri-ang dominated the market with OO and HO scale trains, even buying up Hornby's Doublo, though they soon sold it. As of 2011, they were still producing model rail trains and accessories.
Bassett-Lowke - Bassett-Lowke began producing toy trains in the early 1900s. It's primary period of electric train vitality was between WWI and WWII and for a brief time in the 1950s. Bassett-Lowke tended to use other manufacturers like the German company Trix, for example, to make their products, and they functioned more as a distribution company. The company fell on hard times in the 1960s and was sold repeatedly over the next few decades. As of 1996, it's been operated by Corgi.
Exley - Edward Exley Ltd. produced a number of coaches and cars for Bassett-Lowke in the 1930s, until WWII. After the war, Exley produced made-to-order locomotives briefly, but discontinued this in the late 1950s. Exley manufactured coaches until 1962 when the factory burnt down, with only minor distribution of outsourced products after that until 1995. In 1999, it was bought by Quintin Lucas. As of 2011, Exley was performing restoration work on their highly valued cars but not producing new products.
