If you want to get really technical about it, the train tracks in Chicago are at ground level. You can tell because they're at the same level as the adjacent Chicago River -- look out on the east side from any platform -- and that probably defines ground level. The *streets* in the area, however, are practically all elevated. (Chicago Union Station actually has *two* more basement levels below the track level, which are underground. They recently replaced the heating/cooling equipment in the deepest basement, which must have been a challenge.)Chicago is underground. You have to walk up to street level.
In Los Angeles Union Station, the tracks are actually elevated above the station, which is at ground level.
Syracuse, NY and Rochester, NY both have tracks elevated above street level. In the case of Syracuse street level is ground level. In Rochester, the tracks are elevated about half a story and the streets crossing under them are depressed about half a story...
Reno, Nevada is in a very recently constructed trench which is really very deep below ground level. It's quite the Brutalist monstrosity.
