The $3.50 go-anywhere ticket to fight climate change

Austria is launching a new transport pass, Klimaticket. It gives passengers unlimited rides on trains, buses, trams and metro lines that costs about $3.50 (3 euro) a day.

(CNN) — You wake up in suburban Innsbruck, the snowcapped peaks of the Austrian Tyrol glistening in the distance. After breakfast you hop a tram to Innsbruck Hauptbahnhof, the city's main railway station and climb aboard an Austrian Railways ÖBB Railjet bound for Vienna.

After more than four hours crossing some of the prettiest scenery in central Europe, you arrive beneath the undulating zig-zagged roof of Wien Hauptbahnhof, from where you head down into the curving tunnels of Südtiroler Platz metro station.

After rumbling through six stops of the city's U1 metro line, you reach Praterstern, not far from the shores of the Danube River. From there, it's a short stroll to catch a regional train on the S4 line, heading north a further nine stops to Korneuburg.
