Hornby Dublo was first introduced in 1938 and continued production until 1964 and was approximately half the size of the O gauge system that Hornby had been manufacturing since 1920. Production of the 3-rail system ceased in 1959 due to poor sales and the established 2-rail system was adopted instead. A feature of the range was the cast metal bodies on the locomotives. The range has remained popular ever since with collectors.
