If the game had the city at decades 1950 through 2030 then we would drive first a few routes, then changed routes and trams, new routes, newer trams. That would make sense of the bogus history. But as it stands, it seems a silly waste of effort better put into QA for those who will stay on as your game players.
If there were certain eras that we went through like in Transport Fever that could have been really cool, but rebuilding the city multiple times over would have been a massive task.
