This is the second in my museum series, if one could call the Citadella a museum. The Underground Transportation Museum is located in the Deák Metro station, appropriately enough since it only houses the history of the metro (subway) lines in Budapest. I have passed this place thousands of times in the last five years, have been curious about it, but never bothered to go in. There is another transportation museum in Budapest, which is outdoors.
The ticket office directly outside should not be confused as the ticket office for the museum. This is the ticket office for the metro. The museum ticket office is immediately inside, not that it much matters since it looks just like a metro ticket office and the tickets are identical. Entrance for adults is 185 Huf, less than $1.00. Your receipt for entry is an individual ticket for riding the public transport in the city. There is no difference whatsoever. It is not certain if you have regular metro tickets if you could use this in lieu of buying one, but it would make sense. The ticket seller validated the ticket just like one would when going on a bus or tram.
It is basically is the history of the subway (metro) system in Budapest. It is impressive when you find explanations and other information in English in any foreign museum. Though we were not expecting this here, it was a pleasant surprise to discover everything had been translated. After reading all of the information available, goggling at the old subway cars that were on display from different eras, we had only needed one hour for a thorough tour. I ward it three hearts out of four. It is concise, educational, informative, and there was English. Transportation is not in my top ten categories of favorites, but this was well worth an hour and you cannot haggle over the cost of admission. I give it three stars!
