The train is about 8 hours between the two. I'm now planning a trip to Andalusia in February. I think you could easily spend 8-9 days there, adding Cordoba and/or Cadiz. Weather will almost surely be better in Spain. April in Prague. . . well, Prague is farther north than any US state except Alaska. Posted by Douglas. Curiosity Travels: Battle of the Beautiful Cities: Prague vs. Budapest ; Budapest Local: 5 Reasons Why You Should Choose Budapest Over Prague ; Nomad Epicureans: Prague vs Budapest: Which One to Visit The Sofia, Budapest, Warsaw and Prague metro networks use standard gauge (1435 mm) and receive power from the 3rd rail via a bottom-contact shoe, except in Budapest, which uses top-contact shoes. The trains usually have a flexible formation, of 2 control cars at each end, and a variable number of trailer cars in the middle. There is no high-speed rail line between Prague and Budapest, which is why train still takes more time than a plane. Plane will eat you about three and half hours of time (1,5 hours for early arrival to the airport, 1 hour actual flight time and another 1 hour to get to and from the airport in origin & destination). 6YOf0ck.
