Выглядит красиво :)

Route 12 will be an interesting one: partially a (former) railway line, partially a real tram line. TT (tram-train) then really applies here.

Unfortunately, the date of operation has been pushed back again. Whether 2023 is still possible remains to be seen; 2024 seems more likely.

For those here who do not know how public transport is organised in and around Paris, I would like to give a brief explanation.

Île-de-France Mobilités is the authority that organises public transport.
They do tenders for routes, or route bundles (in the case of buses).
The winner of the tender receives a contract for several years for the operation.
Autobuses can be changed owners or shifted to another entity very quickly. Double numbering, as seen here in the picture, is also a logical consequence. Both the authority and the executor have their own numbering and this is clearly illustrated here.

Excuse me, Alex, I didn't get it; can you explain please what is the double numbering and where can it be seen?

Sorry, wrong photo.
