Post World War II, Tatras continued to be built; the factory was nationalised in 1946 after the Communist takeover. Although production of prewar models continued, a new model, the Tatra T600 Tatraplan was designed -- the name celebrating the new Communist planned economy. It went into production in 1947. In 1951, a decision of the state planning department decided that the Tatraplan should henceforth be built at the Skoda plant in Mlada Boleslav, leaving Tatra free to concentrate on trucks. This was quite unpopular with the workforce at both plants, as a result Skoda built Tatraplans for one year only before the model was discontinued in 1952.
