One of the first tramlines between towns jn Germany (as opposed to inner-city lines) was the OEG (Oberrheinische Eisenbahngesellschaft) which ran (and still runs) on a circular track between Mannheim – Weinheim – Heidelberg.  Today it is connected to various other tram systems serving the larger Rhein-Neckar-area.  Locally, it is still affectionally known as OEG = Oh, Ewiges Gewackel, or O, Everlasting jiGgling, even though the carriages are much more comfortable today.  The official name – Linie 5 – has not caught on.

Waiting for the ÖG.

And here she comes. (Yes, this electric train is thought of as female.)
