Welcome to Space Station ASTA DIMMI.
At the edge of the Milky Way, just before routes expanding to the several reaches of the universe, and a main route to the Andromeda Galaxy, home the Nebula Xeviors--
There is a space station. Most popular for it's train routes, which travel on light beams for fast transportation from Galaxy to Galaxy, and the containments within them.
Asta Dimmi's popularity has lead to it being a sort of representative for the Milky Way, even though it was constructed by the Andromedorian Nebula Xeviors.
Acting as the most popular of waypoints through both exiting and entering it's galaxy, it has high traffic. Carrying four light routes, all passenger. And it doesn't stop there, several light routes connect to all four. Much how all rails in a county called the United States, on a planet called Earth in the home galaxy of Asta Dimmi, happen to all compress to a city called Chicago.
While the space station may be a waypoint at the edge of the Galaxy, it is not exclusively for passengers. In the orbs it contains observatories, for both leisurely and security purposes, depending on the level one is at inside them.
The center of the station contains a docking bay, and several laboratories contained within for research and testing.
The cones at the edges of the station act purely as observatories for security only.
The ring where the trains dock are obvious, for travelers. Located within are a series of shops, restaurants, and the like as any train station would have.
And lastly there is the half-ring, the biggest part of the station. Here contains hotels, residency, acts as an observatory of it's own of the entire structure of the station, gardens, you can think of all the possibilities for one living on the station.

Yes, it is far more than a train stop. It is a fully operational, but miniature, city if one would so consider it.
But is certainly nothing in compare to the city that is home to those who built it... I wonder what that looks like?
