Coming from a place with pitiful public transport (looking at you Seattle), it took me all of 10 seconds to develop eternal love for Berlin‘s comprehensive public transportation. It only took a few seconds longer for me to have strong opinions on what is and what is not acceptable when riding public transportation in Berlin.
The thing is, everyone rides public transport in Berlin. Unlike more elitist systems in places like New York City, the young, the old, the poor, the well-off, the tourists, and the locals all ride the rails around this massive city. You really don’t need car as you can usually get within a block or two of where you want to go with its elaborate system of buses, trams, U-Bahns (underground), S-Bahns (above ground rail), regional trains, and even ferries. Run by BVG (with some assistance by Deutsche Bahn), it is truly a marvel.
