I saw a picture online recently that someone else had taken showing the former PRR/GR&I section house near the diamond at Sturgis, MI, had been torched and is now half charred. I'm not sure if MSO used the building for anything. Sad to see another small part of the historic railroad fabric in Sturgis disappear, not to mention the GR&I and PRR in Michigan. I believe the Mendon depot met the same fate well over a decade ago.
Here's a photo of an MSO local passing the section house in the spring of 2007. The diamond with the Old Road is between the section house and warehouse (International Paper) behind.
