Kerry Doyle: That strikes me as an IC architectural style.

Dennis DeBruler commented on Kerry's comment
Indeed, this must have been an IC+GM&O Depot. The side with the semaphores and ironman for train orders was along the IC.

Everett Lueck: AT that time the depot was in the southeast quadrant of the crossing, with the interlocking tower in the southwest quadrant. When the new depot was built in the northwest quadrant, it incorporated the interlocking plant as well.
