Märklin, in Germany, has produced several different lines of trains that can be considered 1 gauge. Their first production took place in the late 1800s, with a line of "tinplate" type trains. This line was discontinued in favour of their more popular 0 gauge trains. In the late 1960s, Märklin re-entered the large scale market with a modest range of 1 gauge trains. Based upon one drive mechanism made of metal, Märklin produced both a German Class 80 0-6-0T steam locomotive in two different liveries and a 0-Co-0 diesel based upon a Henschel design. This early range included two-axle passenger cars, two-axle box cars and tank cars, all made of plastic. The tank cars could hold liquids and the box car and passenger car had operating doors. This range continued in production for a number of years, but was gradually replaced with more accurate locomotives and larger cars. The range expanded to include a Class 38 4-6-0, a Class 78 4-6-4T and a Class 212 Bo-Bo diesel. In the late 1980s the Märklin 1 gauge line included a large number of freight car designs in different liveries and a range of three axle passenger cars. The earlier passenger cars and box cars were retained, while the tank cars were discontinued.
