Yes, they turned DC Union Station into a shopping mall, but it is a successful shopping and restaurant mall that generates significant revenue to the redevelopment corporation that runs the station. Which gets back into maintaining and improving the station. BTW, the lower level space where the food court is will have a Walgreens opening soon. Might be useful as a place to get needed supplies for those making connections between LD trains at WAS.This is good news, but the 2019 Completion date is optimistic! I wouldn't bet the house on it being completed on time or budget!
And how are the repairs coming along from the earthquake that damaged the Washington Monument and Union Station?
I've always thought that it was too much like a Mall, and had lots of wasted space not used for passenger service that perhaps the remodel will remedy if the announced plans are correct!
As for the earthquake damage, I think they fixed almost all of it a while back. But in the course of repairing the damage to the ceiling in the main hall, they discovered problems with peeling gold leaf and crumbling plaster. So the repair work was expanded for a more extensive repair and renovation, which is still going on. USRC webpage on the main hall repair.
