Wyoming Yard was the heart of the Pere Marquette, at the convergence of lines connecting Grand Rapids with Chicago, Detroit and Petoskey. Saginaw, with its lines radiating into mid-Michigan and the Thumb, boasted a larger number of the PM's lines, but was well north of the PM's key cross-state artery. With major locomotive and car shops, Wyoming Yard was central to the PM's operations.
In 1911, a 42-stall circular roundhouse was erected at Wyoming Yard. During the modernization program of 1923-25, its stalls were lengthened to accommodate longer locomotives. In 1946, it was joined by a brick diesel house to service the diesel switchers and the soon-to-arrive passenger diesels.
As Wyoming became less important to the C&O and later the Chessie System, the need for the roundhouse diminished. Wyoming was no longer the site of major locomotive repairs, and fewer locally-originating trains reduced the need to store diesels there. In the mid-1970s, the first few stalls were demolished, with the first 18 stalls gone by 1981. When this photo was taken in 1982, only an electrical equipment shop remained in the old structure, and that only occupied five stalls. Shortly after this photo was taken in 1982, work began to demolish the last remnants of the building.
