Naw . . . this is the kind i'm talking about:
I don't think you could have fit the kind of stove you show into a caboose--leastways, not and be able to walk past in the winter without burning yourself. The kind i'm showing here is what we had in our "cabin." Originally, it was a milk shed, and that's railroad, too. Dairy farmers would deliver milk to the milk shed, and stack up the milk cans in them . . .
The milk train would come through first thing in the morning, and pick up the milk cans. They were still doing that when i was a boy, and my grandmother would get a can of milk off the train a couple of days a week. Later, of course, diesel trucks took over that operation.
As you can see, there ain't much to a milk shed . . .
My grandfather bought one from some farmers after the milk trains stopped running, and hauled it up to the lake. We used it for a few years, and then my grandfather build another large room on one side, and the milk shed became the kitchen for our cozy little house in the woods.
