由Venice St Lucia departure at 8.44pm and arrive Vienna Westbanhof around 8.30am on the next day.

Vienna (Wien Südbahnhof (Bstg. 01-09)) to Praha, 車程若4hrs, direct train by Super City train (SC) or EuroCity (EC).
You can check OBB (the Austria official transportation) http://www.oebb.at/en/index.jsp
