Rokal TT History
by R. O'ConnorTT-Gauge is smaller than the more common HO-scale size, but is larger than N-Scale and Z. TT-Gauge is considered to have been established by Mr. Hal Joyce, of Indiana, USA. Mr. Joyce's firm, H.P. Products, manufactured TT-Gauge trains from about 1946 until about 1965. Rokal's production roughly followed this general pattern, starting production in about 1947 and ceasing production in late 1969 upon the death of the owner of the company, Robert Karmann. Other manufacturers were involved in TT-Gauge production, notably Kemtron, a U.S. manufacturer of metal locomotive kits. However, TT-Gauge was very popular in the Eastern Block of Europe, especially in the former East Germany. The firm Zeuke, and later the firm Berliner, manufactured TT, continuing production up until the reunification of the two Germanys. Production of the Berliner line of product continues today with the firm Tillig. Recently, the Austrian firm of Roco has announced some new TT items.
TT-Gauge was popular because of its small size. In 1960, Arnold Rapido, of Germany, and Lone Star, of Great Britain, introduced an even smaller size. Originally called "OOO-Gauge", this smaller size would become the very popular N-Scale. In 1972, Märklin, of Germany, would introduce an even smaller modeling scale, Z-Scale. Z is the smallest commercially produced model train scale in the world.
TT-Scale retains some degree of popularity in the world. In particular, it remains very popular in eastern Europe, but there are enthusiasts throughout the world. Rokal was very oriented toward exporting its products from Germany, and this site is a long term result. Rokal is now part of history, yet its legacy continues.
