The series premiered in
1949. Stopped in 1963.
This humoristic strip describes a jovial tram
conductor operating at a fictitious line in Copenhagen called
Line 0. We follow the nameless conductor on his daily route
where he efficiently deals with all sorts of occurring events. A
few of the passengers such as certain children are recurring;
two of the most often seen are a couple of twin girls who are
never lost for words.
The series' title is rather untranslatable but it mainly refers
to the route (Linje Nul in Danish) in an affectionate way. The
term can also mean an unsignificant man.
