The Museum of Transport (Közlekedési múzeum) in the city park is very easy to reach by public transport. There are trains, buses, cars and models, and outside is a 424 steam engine. They often have special shows at weekends.
Kossuth Múzeumhajó is an old steamboat made in 1913 in the Ganz Danubius Works and served as a ”farmer’s boat”- picking up farmers and their produce in south Hungary and bringing them to the Central market hall in Budapest. Today the boat is also a restaurant, but everybody is welcome to enter and look around. The boat is right next the Széchenyi Chain Bridge on the Pest side.

Földalatti Vasút Múzeum is the underground museum at Deák Ferenc Metro stop, it commemorates the first Metro on the continent which opened here in 1896, 1000 years after the arrival by the first Hungarians in 896). There is a reconstruction of an original underground stop with beautiful Zsolnay tiles, and of course the underground carriages, all made of wood!
