This train set was manufactured by Marklin and Company in Germany during the 1920's. It is O gauge, which is a size for train sets and tracks. The O gauge size was developed by Marklin and became an international standard for train manufacturers. The train set includes a locomotive, a tender and a caboose. The locomotive and tender are model 1041 which were made with either a four-wheeled or six-wheeled tender. This is the four-wheeled version. The locomotive is powered by a clockwork mechanism. The caboose is model 18080 and features sliding doors. Since thse are all the same size, they could be hooked together as part of one train set. Marklin was the first manufacturer to offer entire layouts that were sold in individual pieces.
