looking for tram route in germany

[misterchugg]

hello all

i am new here and i was wondering if anybody knew of any tramroutes in the town of mannheim.
the suburb i was born in was called friedrichsfeld.

there used to be a lot of tramlines running all over the countryside connecting small towns and villages.

i am wondering if it is possible to either
A: recreate this or
B: if sombody has already built even a partial route
