Tri-ang

George and Joseph Lines made wooden toys in the Victorian age, at their company being G & J lines Ltd. Three of Joseph's sons formed Lines Bros Ltd soon after World War I hence the Tri-ang. Rovex Plastics Ltd was founded in 1946 by Alexander Venetzian, who was asked to develop an electric toy train set for Christmas 1950.

Lines Bros were looking to expand into railways and so they purchased Rovex, selling their products under the Tri-ang Railways name from 1951. The success of Tri-ang meant that British competitors Trix and Hornby-Dublo were affected. In 1964, Hornby-Dublo was purchased by Tri-ang, including a large amount of stock and the combined toy railways was marketed as Triang-Hornby.
