Each year around Midsummer's Eve, as part of a Europe-wide initiative, museums in Hungary keep their doors open late into the evening and offer special programmes for visitors.
The Transportation Museum is hosting a parade of classic and antique cars for the fourth time for this year's Night of Museums.
If the weather is good, a hot air balloon demonstration will take place behind the Petőfi Hall, a short walk from the museum.
On display will be a prototype for a new Hungarian-made environmentally-friendly hybrid car that has caused a stir in the automotive industry.
Visitors can watch as experts start up an aircraft engine, and they can see police dogs prevent a bicycle and a car theft.
The museum will run special shuttle buses from 7pm. An old omnibus will take visitors to the Hungarian Railway History Park, and an IK 620 open-top city tour bus will go to the Ferihegy Airport Memorial Park.
At "Call the Engine Doctor", one of the museum's restoration exports will tell visitors about maintaining a scale model of a 424 steam locomotive, one of many that are part of the museum's permanent collection.
