In the Greater Berlin area, there are three small tram operators east from Berlin, which offer a nice contrast to the urban traffic in the city. The first is the 6 kilometre long
→ Strausberg railway, which is still called "railway", because it has emerged from a freight railway branch line. There is also an interurban tram from Berlin-Friedrichshagen to Rüdersdorf, the
→ Schöneiche-Rüdersdorf tram. The 14 kilometre long line is the only route with metre-gauge tracks in and around Berlin. The third is the
→ Woltersdorf tram, which runs on an approx. 6 kilometre long route from Berlin-Rahnsdorf to the Woltersdorf water lock.
