Around twenty years ago, a rail car repair company official decided he wanted a caboose for an office. It arrived one afternoon, so we prepared.A section of complete rail was placed, with stops of both ends. There was no immediate access, so we lifted the caboose, then lifted the trucks, placed the entire caboose back on the new rail, and I had the opportunity to look inside. It was complete. Everything was just as it was used during service, but that was soon to change. The final result was a modern office, with little to show it was once a caboose, when you were inside.
I noticed the exact same setup in Penhold, Alberta on the weekend. I suspect there are a few more like this. A caboose would be unique as an office.
