Mother of God, not museum vehicle?! Naples can suprise! After several visits, I was 100% sure only AnsaldoBreda Sirio trams are in passenger service.

@I.L.
I was just as surprised as you are when ANM announced that the last 10-12 (?) remaining CT139K's would re-enter regular service again in December 2024 on the newly created route 422 (former route 2), after they have been standing still for over 8 years. I believe that this 422 is meant to be some sort of 'heritage line' for both tourists and regular tram passengers, like the small yellow trams in Milan and Lisbon.
