I’m told by reliable authorities that our part of Iowa is Milwaukee Road country. Technically, that’s the Chicago, Milwaukee, St Paul & Pacific railway in its current iteration, shown here in a route map from earlier in the company’s history. That has implications for Agincourt in how directly the city is connected to the mainlines; whether it’s a spur or loop.
It also narrows the types of depots built along its route, varying with time and community size. I’d like it to have been something like this one from Pulaski, Iowa, date unknown. I’m fairly certain this was a Milwaukee Road station, because I found another preserved example from LaMotte, IA from circa 1911 that is damned close to being a twin to Pulaski.
The door and adjacent window are reversed, the brackets are a bit different, and the siding runs opposite, but this is substantially the same. That difference in siding looks like a change in style from the 1880s to post-1900. Chances are very good that Agincourt’s earlier depots — I have no idea how many there may have been — might have been built on this pattern.
