REA Transfer

I keep posting photos of passenger trains where I mention pulling off the head end cars and taking them to the mail docks.

I earlier posted a picture of those docks in Kansas City [link] and while browsing though my slides I found this clear shot of the Railway Express Agency warehouse off the Union and LaSalle Street Station's lead tracks south of Chicago's loop. It's a bit hard to see but there are 2 SW's shuffling cars back there in the shadows.
