Yeah the green roof would replace the ugly
gravel roof portion above the stationhouse, and tidy up all of the mechanical equipment in that area.
Supposedly it will also include a 3rd platform on the east side that will turn this from a 3-track station into a 4-track station. A 4th mainline track is needed through this area once South Shore starts running their West Lake trains to Dyer.
Overall this is a much-needed investment in a crumbling area of Grant Park. Hopefully they can do Congress Plaza next... for such an important part of the cityscape and a historically important site of protest, it's really in terrible condition.
