ハンガリー共産党
In 1947, the Hungarian State Railways (MÁV) company decided that a railway operated by children would be built. For the railway construction several sites were considered, including the neighbourhood of the Gödöllő Palace, Margaret Island, and the Népliget, but finally in 1948 the Hungarian Communist Party choose the Buda Hills. The construction started on 11 April 1948.
