Rokal began manufacturing its model train line in the late 1940’s, probably around 1948. Initial model train development was under the direction of Eugen Englehard, who left the company in the very late 1940’s. Development continued under the direction of Heinz Thieme.
At that time, TT-Scale was in its infancy, yet to be discovered by model railroad enthusiasts around the world. Even the Rokal company itself was a bit reluctant about its role in the model train world. The words describing the Rokal factory in the Company's catalogs always were just a bit evasive. "Covering an area of almost 24 acres, ROKAL employs over 2,000, in extensive and modern facilities, in which ROKAL TT gauge model trains are produced as a part of widely diversified metal products". This is technically accurate, but the key phrase here is "...part of widely diversified metal products", since the Rokal factory also produced plumbing fixtures, automobile carburetors, and architectural hardware such as door handles. In short, metal castings.
The electric train business was a sideline for Rokal, more the hobby of the owner, Robert Karmann. Yet, the nature of this manufacture did not detract from the quality of their electric train products. The existence of a profitable manufacturing facility insured that Rokal trains would be produced to high standards of quality materials.
