Chicago, IL: B&O's 1883 Depot

I've already documented that B&O originally built the Brookdale Spur in 1874 to access IC's tracks for their passenger trains. I knew Michigan Central wanted B&O out of IC's station because they did not want to share it with a direct competitor to the East. That is why B&O was willing to join the railroads that were building Grand Central Station. From the "conversation" below on a post concerning Beverly Junction Tower B, I learned that B&O built their own station on the lakefront in 1883. It used that station until its first passenger train arrived at Grand Central Station on Dec 1, 1891. [Brandon McShane comment on a post]

This is Tower B, which controlled the B&OCT crossing in the distance.
William Shapotkin This may sound petty -- and yes the above map does say "B&OCT," but it was my understanding that this piece of railroad was actually known as the "B&O Connecting."
Bob Lalich William Shapotkin - you are correct that the short stretch of track between the Rock Island at Beverly Jct and 75th St was built by the B&O Connecting RR. At the time the B&O Connecting was built in 1892, the N-S stem of what was to become the B&OCT, Chicago Central RR, was controlled by the Wisconsin Central, which in turn was controlled by Northern Pacific. This arrangement allowed the B&O to vacate their own downtown station on the IC near what is today the Art Institute in order to become a tenant of newly built Grand Central Station.
Dennis DeBruler Bob Lalich So the B&O shared the IC tracks, but not their station?
Bob Lalich Dennis DeBruler - my documentation states that B&O used IC's station until 1883, when it built its own station on the IC near Monroe.

The B&O Station was to the north of the Interstate Exposition Building (site of the current Art Institute, as seen on this map.

You can see what appears to be a platform to the right of the building with the chimney.

I added a yellow rectangle to highlight the platform roof:

Dennis DeBruler - here is an article in an IC company magazine that mentions the B&O station. I haven't had a chance to dig deeper yet.

According to this map, the B&O depot was next to the Exposition Building.
