The Study Collection was added a new unit called Mobileum in 2008. The collection is to be found on 500 m2 with interactive material, including 130 giant equipments and further 150 small items about the most important stages of machine development in the past 150 years. Steam engines Hungary made engines and also pumps and turbines: all are ready to operate.  The visitors to the machine hall may 'discover' themselves how the really old machines worked.
