The Museum of Transportation commemorates the 125th anniversary of electric transport with a very special one-track 122-year-old but functional tram. This exhibition is part of the one related to the technological history of Dualism, entitled Free to Go. The visitors will learn about so-called under-wire electric supply called Budapest System, how trams improved and the first HÉV trains.

The first tram began its first journey at half past two on a Monday, on 28 November 1887 in Budapest. Before that one, however, a HÉV (Local Train) steam railway started off from Közvágóhíd to Soroksár. With these two trains, public transportation in Budapest began. Electric transportation was soon popular. By 1898 superseded horse carriages. Two companies operated electric cars in Budapest, with their own rail track systems.

By the turn of the century, more trams ran in the small narrow streets of Budapest than in Veress Pál or Papnövelde Streets. In order to make tram transportation safe, a number of plans were devised. The most interesting in terms of technicality, the one designed by Károly Zipernowsky is the most interesting. It was a one-track design, he called  Vertical Track Train. To support the patent documents, the first tram was produced in 1890 in the GANZ Factory, on the scale of M=1:5. It was a functional tram, with a track of 10 meters.

Restorers of the Museum of Transportation restored this model for the 125th anniversary. The Zipernowsky train is considered an artefact, with technological solutions of over 120 years of age. Because of these, we only start its engine at hours and dates announced previously. We show video recordings of the model in operation in opening hours of the museum.
