There are lines in Karlsruhe which use only the tram current (750 Volt
DC), e.g. line S1 from Hochstetten via Karlsruhe to Bad Herrenalb. This
line shares tracks with freight trains between Lepoldshafen Frankfurter
Straße and Welschneureuter Straße. That's similar to the train track in
Waterloo.

It does not share the space but according to your photos at Twitter the
trackbed seems to be paved and cars could use it. A proper light rail
has either ballast or grass between the tracks, i.e. car drivers will
recognize that the cannot use this space.

There is no sharp border between trams and light rails.
