If so, I must not be on the same City page as the actual transit system. IMO it might only feature past and current system, and official futur systems, no personnal projects.

@Kalepom the thing is that there have been many cases of people adding invented lines - or even systems - to cities. Maybe we don't have to do anything about this, but perhaps there is a way to allow these kind of contributions as a way of handling this "problem". As you say, if we do this, it should be a different screen and it should be very clear that it's not part of the actual system, but a personal project of a specific user.
