So for a while, I've been noticing that St Charles Air Line (which Amtrak's City of New Orleans and Illini services use to access the former Illinois Central) via google maps has been downgraded from being double tracked to have a single track, with something similar happened around the 21st Street Crossing where trains from Union Station join the former Alton Railroad to travel down to Joliet and St Louis...but mostly the St Charles Air Line downgrade has been more of a source of confusion. And all I have to ask is this:
WHY?!
WHY?!
