This is quite literally, my favorite place to shoot on the CN Waukesha. When I heard "NS 1056 South, stop indication, South Duplainville", I knew exactly where I had to get to. Some creative driving and a northbound later, here was A446 with one of NS's tough looking ACes on point.
Oh the stories these special buildings could tell. Originally the brains of the rails they monitored, working to insure effecient rail service for our nation! A tribute!
