You get to sunrise the same way you do in the real world; wait.
Bajor has new game tech.
I know that. The forklift truck only gets me on that one building.
The catwalk then gets me to the sunset side.
However, I have no clue how to get to the opposite
edge of the city in order to watch the sunrise from there.
you don't... go to the edge of the building and watch it... the rendering will disappear from most angles and you get a clear view of it.
