wagons that could act as a car or train. The name Duplo was brought back in 1979, along with a new reworked logo. Some brick sets were sold inside a plush version of the rabbit from the logo, that zipped closed. In 1983, other Duplo figures appeared, often called Duplo people. These figures have a moveable head, arms, and legs and look like large Lego minifigures, but cannot be taken apart, making them safer for small children. Also in 1983, set number 2700 was introduced with a model of a steam engine with two train cars. In 1986, a Duplo doll house with sliding doors was introduced. This included a Duplo people mother, father, and smaller child. In 1992, Duplo Toolo was introduced, which was a range of construction sets using screw drivers and was aimed at children between the ages of three and six. 1993 brought a grey rail train system with a stop and start track. Later, two more train systems arrived. In 2005, Lego started selling Duplo trains themed as Thomas the Tank Engine. In 1995, Duplo Primo was launched, which was a line aimed at children aged between 6 and 24 months. Most of the products in this line were not construction toys. Duplo Primo was later renamed Lego Primo. The name Duplo was dropped again in favour of Explore in 2002. The new brand name was used to emphasise the relationship between the bricks and the child's learning. Explore introduced four different ways of exploring play: explore being me; explore together; explore imagination and explore logic. In the 2004 spring catalog, there was a reminder that Duplo was now called Explore, but that fall the well-known Duplo name was back yet again with a new rabbit logo designed to match the new elephant logo for the Lego Quatro range. Lego have made Duplo sets licensed with Bob the Builder and Thomas & Friends characters. Those Duplo ranges have been discontinued, but Duplo sets now include farm, zoo, town, castle, and pirate lines. A doll house and princess castle are available as of 2008. Some Duplo sets have cars, trucks, and buildings which cannot be disassembled. Some DUPLO sets do not include building manuals. Production Lego Duplo is manufactured at a factory in Nyíregyháza, Hungary. Over 90% of all Duplo elements are manufactured at the plant, alongside traditional Lego bricks.
