I think manual label placement is necessary in terminal stations like Budapest-Keleti. Even if all the tracks within the polygon are considered part of the station, they’re clearly arranged to serve a passenger facility at the end of the tracks. An automatically-placed label in the center of the area would be misleading to railroad passengers and workers alike.
At several major stations in North American cities, the tracks are tucked away in a vast basement, with a street-level entrance building integrated into the urban fabric above. For Grand Central Terminal in New York, the label is currently placed over the center of the station building, from the passenger’s perspective. Automatic label placement would probably put Grand Central somewhere along 46th Street, which would look bizarre to New York commuters, as well as confusing to tourists looking to marvel at the architecture. Besides, Grand Central is Mile 0 for various railroads heading north out of the city—it only makes sense to put the label near where the tracks start.
