While hardly a Calatrava "Oriente Station"masterpiece, the transparent Alsop-ish atrium and green roof (crosses fingers they do it) are huge improvements... hard to tell the true scale of the atrium since renderings exaggerate, but it looks like it has the potential to create some real urban drama for passengers and a sense of arrival worthy of Union's important role in the city's circulatory system.
My only disappointment is... I thought the newly completed eastern GO train parking lot would replace those west of Union (not supplement)... freeing up the possibility of more significant (new) north/south connections over the rail corridor.
