Berlin’s tramway network stretches to nearly 200 km. But not all of Berlin’s trams are accounted for in this figure. After I visited every single S-Bahn and U-Bahn stop, I went to every single tram stop in Berlin. Part of that included the extended overland tramway.
Three lines, the 87 Woltersdorf Tramway and 88 Schöneiche bei Berlin Tramway both stretch from an S-Bahn station within city limits to reach villages in Brandenburg state. The 89 Strausberg Railway is entirely outside of Berlin but still within the city’s fare network. Of those, only 87 and 88 still use heritage trams on a daily basis.
It’s called a railway because it runs on standard gauge at speeds of up to 80 km/h to suburban stops with raised platforms for boarding. In the last decade, it’s been rated more like a light railway that runs high-capacity trams. The railway joined the Berlin fare network in 2011 and ordered Berlin Flexity trams that augmented service in addition to its Soviet-era Tatra trams.
My only disappointment is that they didn’t run any heritage trams like on lines 87 and 88.
