It’s unlikely that Agincourt would have been a section point on the Milwaukee Road or its subsidiary feeder lines. In fact, I have to plead ignorance on the mileage between such points. North Dakota is far more regular this way, with four service points along the Northern Pacific and another four along the Great Northern. Iowa’s railroads run every which way and fan outward. So, for the sake or argument, let’s say there had been a section house here, all of which means we may have enjoyed a roundhouse for at least a little while.

Roundhouses were necessarily radial. But, let’s face it: they’re a lot more interesting and present even more opportunity for adaptive reuse — if it hadn’t burned to the ground, that is.

This wonderful RPPC is too expensive for my wallet [$40], so I’m just going to “borrow” the image and spruce it up a bit. Somewhere in the literature of railroadiana there must be some guidelines for dimensioning a building like this.
