During our last trip to Vienna, we planned a few days in Prague despite all of the post covid travel limitations.  We arrived in Vienna the Thursday before Thanksgiving and had three days of pre-lockdown outings.  A few of which included Christmas markets, Heurigens (local run wineries) and hiking around the Anninger mountain.  As the lockdown went into effect, we decided to go ahead with our plans to go to Prague by train.  I have taken the train a lot in Germany but in Austria I had only ridden the subway.  The train was very comfortable, completely empty and quite affordable.  We spent around 50 euros per first class ticket…
